3. Canada Jay (Perisoreus canadensis)

Subject: Canada Jay (Perisoreus canadensis).

Location: Algonquin Provincial Park.

Date: March 2017.

For an Introduction to this series (my Top 20 Nature Photos of 2013-2020) go here.

The Story Behind the Shot: I’ve only visited Algonquin Park in the Winter twice. On this occasion, in March 2017, I was actually searching for this particular bird (one of the rare times that I have a target species in mind, I’ll be recounting another one for my next photo). The Canada Jay had only recently been rebranded as such, the common name used to be the Gray Jay and some people still refer to it as such (after all, common names can sort of be whatever you want them to be). Part of the name-change or name-shift was to do with a campaign by the Canadian Geographic Society to name the Canada Jay (Perisoreus canadensis) as Canada’s National Bird. For more information about this story, see the Canadian Geographic article here: https://www.canadiangeographic.ca/article/meet-our-national-bird-gray-jay. Having read up on this story I wanted to encounter this emblem of our country and was able to catch a glimpse of it in the parking lot of the Spruce Bog trail in Algonquin Park.

The Story Behind the Species: The Canada Jay is a permanent resident of cold northern forests across North America (Cadman et. al. 1987). Algonquin Park is at the southern edge of their range in Ontario (Tozer 2012). Canada Jays are able to live and breed in their northern habitats because of their food-storing abilities. They are highly adaptable birds, feeding on a wide variety of food, obtained in a wide variety of ways. The Cornell All About Birds website sums it up like this: they will “snap up flying insects in the air, wade in shallow water to capture invertebrates and amphibians, kill small mammals, raid the nests of other birds” (https://www.allaboutbirds.org/guide/Canada_Jay/lifehistory). The food they gather in the summer is cached throughout their territories in preparation for the long winter. This food store allows them to start nesting as early as the end of February in Algonquin Park (Tozer 2012). They prefer to nest in spruce forests, and there is some evidence to suggest that the antibacterial properties of some conifers actually work to preserve the food the jays store in them (Tozer 2012).

Amazingly adaptable, clever and curious birds. I certainly support its status as unofficial National Bird of Canada.

2. Moose (Alces alces) Family

Subject: Moose (Alces alces) Mother and Calves.

Location: Algonquin Provincial Park.

Date: July 2016.

For an Introduction to this series (my Top 20 Nature Photos of 2013-2020) go here.

The Story Behind the Shot: For several summers, I have stayed in Algonquin Provincial Park for a week, camping in Pog Lake Campground and exploring various trails and locations along the Highway 60 corridor, attempting to photograph interesting creatures that I encountered. One of the most quintessential Algonquin animals is the Moose, and I didn’t spot one on this trip until we were on our way out of the park, driving down the highway early in the morning. This family group of Moose (a mother and two calves) was an amazing treat to watch as they continued to browse some foliage and walk through the clearing adjacent to the road.

The Story Behind the Species: Moose are large mammals, the largest land mammal that one can encounter in Eastern North America. As such, they have been the subject of plenty of research and interest. For this post I want to focus on their reproductive cycle since the photo I captured features a mother and her two calves. Calves are born in May, after 7 months of growth within the mother. Pregnant Moose will often seek out islands in lakes as the location to give birth as it provides some protection from roaming bears or wolves (Strickland and Rutter 2018). You may be wondering how a mother moose can reach an island that a bear or wolf won’t frequent. Moose are actually quite excellent swimmers, they can feed on underwater plants, can swim to depths of 5.5 m and stay under for more than 30 seconds (Naughton 2012). The two young in my photo are likely twins since they appear to be the same size. Apparently, “twins are not uncommon under good conditions” (Naughton 2012). The young stay with their mother for a full year before they disperse (Strickland and Rutter 2018).

A fascinating animal and one I’m sure I will return to explore further on my blog in the future.

1. The Pale-Painted Sand Wasp (Bembix pallidipicta)

Subject: Pale-Painted Sand Wasp* (Bembix pallidipicta)

*this species doesn’t have a common name, so I created this common name by using the etymology of its scientific name “pallidipicta” which seems to mean “pale-painted”.

Location: Parents’ Farm, Norfolk County.

Date: July 2013.

For an Introduction to this series (my Top 20 Nature Photos of 2013-2020) go here.

The Story Behind the Shot: While growing up, my brother and I discussed several times the idea of a project: to list every single species that occurred on our family’s property. While this project never reached fruition, the idea of it has inspired me throughout my adventures with the creatures in my own backyard and elsewhere. One day several years ago I spent a day just wandering around on my parents’ farm taking photos of every interesting creature that caught my eye. I was amazed to find busy little wasps digging burrows in the sand at the edge of the field. Despite their frenzied activity I managed to capture one at the entrance of its burrow.

The Story Behind the Species: Bembix pallidipicta is one of those Sand Wasps (members of the subfamily Bembicinae) I’ve mentioned once or twice on my blog about a year ago now. The following information on this species is summarized from Evans and O’Neill (2007).

Not all Sand Wasps construct burrows in sand, but B. pallidipicta does, usually selecting large areas of loose sand to begin their burrowing. Nest site selection is fine-tuned in that they require a small amount of moisture in the sand to maintain a fine crust when they tunnel beneath it. The sites where the females emerge and the males mate are often suitable for the females to use for their nest construction, so unless the habitat is disturbed the same site can support a population of sand wasps for multiple generations. B. pallidipicta males gather around sites where adult females will soon emerge, and fly in short hops, which gives the appearance of “aggregations of very small toads” (Evans 1957).

Once their burrow is constructed with a chamber up to 56 cm beneath the surface (the depth is partly determined by the dryness of the sand), the females lay a single egg at one end of the chamber (termed the brood cell). This egg will hatch and the wasp larva will wait within its subterranean chamber for its mother to provide food. B. pallidipicta exhibits what is called “progressive provisioning” which means that the mother brings prey in multiple times to the larva while it is growing and feeding. I’ve always loved this aspect of sand wasps because it’s essentially the same setup as songbirds awaiting worms in their nests. For B. pallidipicta, the prey is all true flies (Order Diptera) of several Brachyceran families, including Flower Flies (Syrphidae), Horse Flies (Tabanidae) and House Flies (Muscidae). When bringing fresh prey to her larva, the mother will push the fragments of partially eaten prey off to the side, and block this debris off with sand. This likely helps prevent parasites or diseases from accumulating within the nest, or it’s possible that it’s a way for the mother wasp to judge how much more prey to provide. Because B. pallidipicta nests in large unrelated groups, females will occasionally steal prey from other females nearby to feed their own offspring. After about 4 days of feeding, the larva pupates and the mother moves on to construct a new nest.

Another view of the same individual Sand Wasp entering its burrow.

My top 20 Nature Photos of 2013-2020 are going to be presented in chronological order of when I took the photos, they aren’t arranged in any other sort of hierarchy. Come back next time for a photo of a much larger animal caring for its young…

My Top 20 Nature Photos of 2013-2020

I think this photo (taken in MacGregor Provincial Park May 2018) of a Snapping Turtle lurking at the air-water interface is pretty neat. But it didn’t make it into my personal top 20 Nature Photo list.

As you may know if you’ve been reading some of my earlier posts this year, I joined the Norfolk Field Naturalists this past Summer. This has meant joining with local nature enthusiasts for hikes (see NFN Fungi Hike posts, part 1, part 2, and part 3) and listening in on monthly presentations beginning in September. The December NFN meeting is going to be a “Members’ Night” in which members of the group can present up to 20 pictures or a short video of trips or observations of their own. I was excited by the prospect of sharing my photos and observations (as indeed I’ve been doing with this blog site).

So… what photos to select for my portion of the slideshow? I decided to present the highlight photos of my own past observations to demonstrate a bit about myself and my experiences.

I realized that I needed to pick out 20 of my top observations/nature photos of all time. At first 20 seemed like a lot… but going through my personal archives of nature photos I soon came to understand that it would actually be quite difficult to decide on which photos to include as I have take quite a few over the past several years.*

*literally thousands of photos of hundreds of species

So, to help narrow my choices down I eliminated this past year, 2021. I did this for a couple of reasons: 

  1. I would like to go over my 2021 nature photos on my blog (and I already have showcased many here), and I wanted to do something different for this presentation, ie. I wanted to review other photos and observations than ones I was already planning to write about.
  2. I believe I have truly improved a lot in my nature photography and I personally think that 2021 contains some of my best photos. If this is true, then this past year of observations might get over-represented in a list of “best nature photos”.

2021 out of the way, I only had about 8 years of nature photos to trawl through for those greatest hits. To decide which photos to include in my list, I considered the following:

  1. First and foremost, they had to be good pictures, high-quality, focused, nice composition. I usually don’t think of my pictures in this way because I’m interested and excited by the organisms involved and not the quality of the photos per se. But for a slideshow I wanted to have only the most crisp clear photos.
  2. Unique or rare organisms or behaviour were preferred. I have taken many pictures of Honeybees (Apis mellifera) and American Red Squirrels (Tamiasciurus hudsonicus) but unless they were doing something interesting or were exceptionally beautiful shots I wanted to compile a list of the more rare (to me) species that I’ve seen and photographed.
  3. Taxonomic Variety. I wanted the photos to reflect my own interests in nature which is pretty wide in scope, encompassing basically all that’s living with a particular emphasis (partly just because I can observe and photograph them more regularly and easily) on Insects and Birds. In other words, I didn’t want the 20 top photos to be a list made up of half Hymenoptera and half Lepidoptera, I wanted to have a good variety of organisms from across the tree of life.

As you can probably tell from the above, the list at the end of the day is quite… arbitrary. It’s my own decision what to include and what not to include, what’s particularly interesting and what organisms are different enough to showcase. I feel like this preamble is more for myself than for anyone else because I think everyone already assumes that a list such as this will be arbitrary but I felt while picking photos I needed to have some sort of guidelines to create a somewhat representative list. Anyway, boring stuff out of the way, next post will be the first of 20 of my top 20 Nature photos taken between 2013 and 2020!

Until then, I will leave you with a few of my photos that didn’t quite make it into my final list:

Blogversary

Happy 2nd Birthday, Norfolk Naturalist!

If you’ve ever spent time around Red-wing Blackbirds then I’m sure you can hear their distinctive ohk-a-lee! call when looking at this picture.

Two years ago today, I published my first blog article on my site: norfolknaturalist.ca. So today, I’m going to celebrate two years of Norfolk Naturalist blogging, by looking back over the past year at what I’ve written on my blog, what I’ve read that is nature-related, and other events and recollections of the past year that are related to the Norfolk Naturalist blog. For last year’s birthday article, go here. So here we go!

Many exciting things occurred over the past year for the Norfolk Naturalist, including an event I attended in December 2020: my first ever zoological conference: Tetzoomcon! I didn’t finish writing up my thoughts on the event until Tetzoomcon 2021 was announced so although the event was in December 2020, the article was posted in August 2021.

Also in December 2020, I published the first article in my Sand Wasps series, the Introduction, and in January of 2021 I published Part 2: the Tribe Alyssontini. I haven’t continued the Sand Wasps series since… my initial impetus to write about Sand Wasps was reading the book The Sand Wasps by Howard Evans and Kevin O’Neill, which I mention in my Introduction article. Basically, it’s a series that I’ll continue when I feel inspired to write more about Sand Wasps.

Sandhill Crane close encounter on the Big Creek trail in Long Point. I would like to do a roundup of top nature photos taken during the last blogging year (especially those that didn’t make it onto my blog this year), but didn’t get that together in time. Perhaps I’ll post a second article later. For now, I’ll post a few of my best sightings interspersed through this article.

In February I wrote an article titled Swimming Squirrels, which was all about a fascinating paper I read in the Canadian Field-Naturalist which described an observation of a Grey Squirrel (Sciurus carolinensis) swimming and catching a fish, behaviour that is surprising to me.

Another unfinished, and barely begun series was started in March with my posting of Natural Curiosities, Part 1: Emu Feathers. I meant to go through various nature objects that I had obtained through the years and describe the organisms they came from or represented, but I only finished the one that’s published. Perhaps the next year of blogging will contain more parts to this series (I certainly have more natural curiosities to describe and write about).

In April I published a Book Review of The Palaeoartist’s Handbook by Mark Witton. Later in the year, I published another book review of Flies: The Natural History and Diversity of Diptera, by Stephen Marshall.

A rather different article was posted in May, in which I examined what the distinction between life and non-life really is and the complexities of the question from a scientific point of view. This article mentions viruses and alludes to being the beginning of yet another series of posts… of which it is the only one so far…

The tail end of June saw the stepping up of my blog-writing. I fell into something of a routine with my writing and found ways to write that felt natural and productive. No longer was I struggling to produce an article per month and for the rest of the year I wrote several articles per month which was a real achievement for myself. First I wrote up my experiences visiting a trail in Long Point, in two parts (Part 1 and Part 2). Then I wrote an article about Wrens (Troglodytes).

After these articles, I proceeded to write and post about the various organisms I had seen and photographed at my parents’ house, and in my own backyard (Diptera, Hymenoptera, and Others) all observed during the month of June.

During July, I went camping at Port Burwell Provincial Park and made several interesting observations there which I wrote up into a post.

The next notable camping trip was to Algonquin Provincial Park, one of my favourite places in the world. While there, I took plenty of photos and saw many wonderful creatures. I wrote up my Algonquin observations into five parts: Part 1, Part 2, Part 3, Part 4, Part 5.

After my long series of Algonquin observation posts, I changed it up a little with a Podcast review of one of my favourite podcasts: The Field Guides. My website was actually mentioned on the podcast in their following episode, which really made my… year, and they added a link to my site on their website which is incredible.

This year, I joined the Norfolk Field Naturalists, an organization of nature enthusiasts in Norfolk County and my first experience with them was a hike in Backus Woods, searching for fungi to photograph. We found plenty, I learned lots, and I wrote up my observations in a series of 3 posts: Part 1, Part 2, Part 3.

Some sort of Polypore mushroom growing out of the side of a tree in Backus Woods.

In addition to hikes with other local naturalists, the group also arranges meetings every month with a presenter. This year, because of the global pandemic, the meetings were done over zoom. So far the presentations have been excellent and interesting, and I might write up more about them in a future article.

Coming up in December is a Members’ Night meeting in which members can submit up to 20 photos of their own for a slideshow. I’ve already submitted my photos and will be blogging about my selection of 20 photos from my personal collection in due time.

Just during November I received the latest issue of the Canadian Field-Naturalist, a science journal that I subscribe to. Within, I was delighted to find that one of the articles mentioned a species that I profiled for my first post on this website (besides my welcome post): the Eastern Band-winged Hover Fly (Ocyptamus fascipennis). I have added an update to this post to reflect this recent interesting note about this species (spoiler alert: it’s possibly migratory).

Nature-related books I’ve read over the past blogging year (from November 30, 2020 to November 30, 2021):

Here’s a quick gallery of the nature-related books that I’ve read over the past year with a short summary of my thoughts on the books. Some of these books have more substantial reviews in the works or already published on my site. The books are presented in no particular order except vaguely chronological of when I started reading them.

The Golden Throng, by Edwin Way Teale:

A book about bees, by Edwin Way Teale, a classic naturalist writer. The book doesn’t go into as much detail as I might prefer, but if you want a book that can ignite curiosity or admiration for bees for someone who isn’t already curious or fascinated then I would recommend this book.

Naked Trees, by John Terpstra:

Excellent poetry about trees, delving into their nature and their interactions with people.

Life through the Ages II, by Mark Witton:

Incredible book, filled with beautiful illustrations of past life and concise descriptions of bygone eras. This book was a wonderful treat in visuals and text. Highly recommended for fans of paleoart or extinct life or the diversity of life (which must include the vast array of extinct organisms).

Behavioral Ecology of the Eastern Red-Backed Salamander, by Robert G. Jaeger, Birgit Gollman, Carl D. Anthony, Caitlin R. Gabor and Nancy R. Kohn:

A fascinating book describing various experiments and research ideas on a single species: the Eastern Red-backed Salamander (Plethodon cinereus) in a specific place: Northeastern United States. I love finding a book like this which contains details about a species that can be found nowhere else.

Half-Earth: Our Planet’s Fight for Life, by E. O. Wilson:

I didn’t love this book. I found it was a bit incohesive and fragmented in tone and content despite being presented as if it was a single argument piece. I disliked some of the inconsistent messaging on science/religion/philosophy of science, but I really enjoyed the discussion of various ecosystems and fascinating organisms that live there. I think Wilson’s writing works best in this book when he’s explaining and refuting the anthropocentric worldview, and I think if it had been more tightly focused on this aspect it could be a more cohesive exploration of the topic.

In the Heart of the Sea, by Nathaniel Philbrick:

This is a history book that recounts the tragedy of the whaleship Essex, which was rammed and sunk by a Sperm Whale in 1820. Not particularly nature-focused, but it does contain some information about Sperm Whales and the whaling industry of the time. Fascinating shipwreck survivor tale.

Parasitism: The Ecology and Evolution of Interspecific Interactions, by Claude Combes:

Composite showing my used copy of Parasitism by Claude Combes front cover and side view. If it weren’t for used copies of books, I wouldn’t be able to buy and read a lot of the books I buy and read (because they’re out of print, prohibitively expensive new, etc etc).

Absolutely incredible book that covers such a broad range of topics that it’s hard to summarize. Describes the process of Parasitism from multiple levels sometimes going very heavily theoretical and sometimes describing particular in-depth case studies of model systems. I learned lots and had a ton of fun reading it.

Dinosaur Facts and Figures: The Theropods and Other Dinosauriformes, by Ruben Molina-Perez, Asier Larramendi, Andrey Atuchin and Sante Mazzei:

Beautifully illustrated dinosaur book with a focus on “records” some of which are bizarrely specific, and some of which are quite fascinating. I think this book is worth it for the illustrations, but there are also a lot of interesting facts as well. I particularly liked the geographical context section because I find that many general dinosaur books don’t give you a good idea of what dinosaurs lived where.

Naturalist, by E. O. Wilson:

Very fascinating look at the journey of a young man growing into a scientist. Interesting to see where different aspects of E. O. Wilson’s philosophy arose from and how they influenced his growth and avenues of research.

After Man: A Zoology of the Future, by Dougal Dixon:

A speculative look at what animals and ecosystems might evolve after another 50 million years. Thought-provoking and very fun way to explore evolutionary ‘rules’ and ideas.

Flies: The Natural History and Diversity of Diptera, by Stephen Marshall:

This book is absolutely incredible, full of amazing photographs and fascinating text. Read my full Review here.

Terns, by David Cabot and Ian Nisbet:

In-depth natural history of British and Irish Tern species, but also covers many other Terns from around the world. Excellent photos and detailed text. I am working on a longer review of this book and will post it here soon.

Days Without Time, by Edwin Way Teale:

The subtitle of this book is “Adventures of a Naturalist” and as such it’s a random collection of chapters, each presenting a different nature encounter of the author. I quite enjoyed this book. Some sections feel a little dated (the book was published in 1948) but the curiosity and sense of wonder that Edwin Way Teale has for nature is something that resonates strongly with me. The final two paragraphs feel like they should be in a banner across the top of my blog:

“The out-of-doors is – as it always has been – everybody’s art gallery, everybody’s concert hall, everybody’s library of poetry written in a universal language. The beauty of nature is every generation’s gift. It is free for the taking, around us always. And each man, according to his character, realizes its possibilities. To dwell with this beauty of the out-of-doors, as much as we can, is the better part of wisdom. Here we feel ourselves losing nervous tension, relaxing like a drought-dried plant in a summer shower. Here the hunger of our eyes for the green of trees and the color of flowers is satisfied. Here the longing of our ears for the sound of wind in the grasses and the lap of waves on sand is gratified. Here there is beauty to lift the heart and calm endurance to speak of courage. And here there is something more, something magical, something that fills a deep need of the human heart.”

Trees of Algonquin Provincial Park:

I read this “book” (it’s a pictorial guide to the trees of Algonquin Park, 40-something pages long) while camping in Algonquin Provincial Park. It brought a greater appreciation for the beautiful trees that surrounded me there.

Cougar: Ecology and Conservation, edited by Maurice Hornocker and Sharon Negri:

This edited volume contains basically all aspects of Cougar ecology and conservation that you could imagine. I particularly found it fascinating to read about Cougars in Central and South America as I’m used to picturing them in the Rocky Mountains of Western North America. As an edited volume, some topics are repetitive and some are not as interesting to myself as others. Overall though, an excellent scientific overview of cougar research published in 2008.

Oakwatch, by Jim Flegg:

Oakwatch describes the species that live in and around oak trees in Britain. Great exploration of the seasonal changes that occur and the trees that tie so many distinct species together. Something to read slowly through the year as the seasons change, which is how I read it.

Grassroot Jungles, by Edwin Way Teale:

A book about insects, with a very relaxed naturalists’ style. I personally prefer the similar book by the same author: Near Horizons: The Story of an Insect Garden for an overview of the insects he has observed in his own backyard. Even so, Grassroot Jungles has the same charm and joy at the everyday wonders that are the Insects all around us.

In Conclusion:

I hope that you enjoyed this look back at the past year at norfolknaturalist.ca! Last year’s blogversary article concluded with a goal that my second anniversary would contain more than 7 posts to summarize and I am happy to say that I have far exceeded that goal! Next year, I hope to stick to my main goal of producing interesting nature articles on various topics that grab my attention, at least once a month. I truly love sharing my fascination with the natural world and hopefully inspiring others to take a closer look and keep learning. If you enjoy my writing and photos and have the means and desire to support me, I now have a donation function set up on my Home page. I really appreciate any level of support, which includes most importantly sharing my website with others who might find it interesting or worth a read.

Here’s to many more years of norfolk naturalist blogging!

book review

Flies: The Natural History and Diversity of Diptera, by Stephen A. Marshall

People are always going on about how Beetles are so diverse, biologists are always explaining to theologians that God must really love Beetles*, and whenever anyone asks “What’s the most diverse group of organisms?” Beetles are always top of the list. UNTIL NOW.

*in case you don’t know the anecdote this is referring to, the earliest source (according to quoteinvestigator.com) runs thus: “There is a story, possibly apocryphal, of the distinguished British biologist, J. B. S. Haldane, who found himself in the company of a group of theologians. On being asked what one could conclude as to the nature of the Creator from a study of his creation, Haldane is said to have answered, “An inordinate fondness for beetles.”” (Hutchinson 1959).

Stephen Marshall proposes in his magnificent volume on the diversity of flies that there are historical reasons why beetles are held up as so diverse when the truth is that they might just be more closely studied than other insect groups… other groups like the order Diptera (true Flies), for instance. And if you read through this 600 page volume loaded with superb photographs and covering every single family of flies in some detail you will come away with the powerful impression that Stephen Marshall is on to something. Flies, a group often neglected because they don’t always photograph well, many look very similar to each other, and a lot of them have distasteful feeding habits, are showcased as the hyper-diverse evolutionary marvel that they are.

Metallic Green Long-legged Fly (Condylostylus sp.), photographed in my backyard, June 2018. I’m just going to post some of the many interesting flies that I’ve photographed myself throughout this article. Stephen Marshall mentions that digital photography is opening up the realms of entomology to amateurs in a way that hadn’t been possible in the past. I wholeheartedly agree!

The book’s first part: “Life Histories, Habits and Habitats of Flies” runs through a sampler of what flies do as larvae and adults. This includes the life cycles of Diptera in general, but elaborates on more specific groups where appropriate. Other sections in this part describe flies interacting with plants, fungi, invertebrates and vertebrates. This entire section comprises about 90 pages and goes into considerable detail on specific guilds* such as the worldwide coastal communities of “wrack flies”, flies that have larvae that feed within decomposing piles of seaweed washed upon shores. Along with the various interactions between flies and invertebrates, this section also includes a discussion of the many human diseases caused or carried by flies such as mosquitoes (Family Culicidae) or house flies (Musca spp.).

*A guild is a group of animals that are united by a common feeding strategy or resource use, but not necessarily united in relatedness. For example, flies from different branches of the Dipteran family tree are considered part of the leaf-mining guild if their larvae produce mines in leaves.

Eutreta novaboracensis, a Fruit Fly of the family Tephritidae, photographed in my backyard, June 2018.

The second part of the book is titled “Diversity” and reading through this catalog of fly families and subfamilies truly does drive home just how incredibly diverse the Order Diptera is. Each chapter covers a large portion of the fly family tree and opens with a diagram of the proposed relationships between the fly groups within. This opening section of each chapter moves from family to family, and describes the basic characteristics of each group detailing subfamilies where possible as well. Within these descriptions are not just lists of characters used to distinguish one family from another but also the basic biology of each group when known. A couple of key things to note here: even when dividing up the flies into smaller and smaller groups it can be hard to generalize because you are still dealing with huge swaths of species in some instances and in others you are simply dealing with species doing very different things despite their close-relatedness. Marshall does a good job of explaining this and I’ll provide an example here from the section on Tipulidae (the Crane Flies, of which there are more than 15 000 described species): “Although most larvae with known biologies are saprophagous and eat microbe-rich organic matter (normally, decaying plant material) in wet environments, some crane flies are predaceous, fungivorous or phytophagous… Some groups have become specialists in extreme environments such as caves, marine intertidal zones and deserts, but most occur in humid forests and wetlands. Most Tipulidae are unknown as larvae.” (Marshall 2012 p. 110).

The above quote demonstrates the way in which Marshall overviews the lifestyles of the fly groups providing tantalizing glimpses of their diverse life histories, but it also provides an example of something that is rife within the 600 page volume: the overwhelming amount of flies or fly habits that are unknown. To demonstrate, here are some quotes from throughout the book (Marshall 2012):

Valeseguya rieki is known only from a single male specimen” (p 136)

“Larvae and larval habitats of the Lygistorrhinidae remain unknown” (p 141)

“Nothing is known of the biology of these obscure little flies [Ohakunea]” (p 141)

“adults of Oreoleptis (and thus the family Oreoleptidae) have yet to be collected in the field” (p 198)

“The 500 or so species of Acroceridae occur in every part of the world, but most are known from only a few specimens” (p 205)

“Essentially nothing is known about the biology of either Apystomyia or Hilarimorpha” (p 235).

“Even though signal flies [Platystomatidae] are usually conspicuous and attractive flies, many species remain undescribed.” (p 332).

“Larvae are unknown for most species in the family [Lonchaeidae] and little is known about behavior” (p 335).

“The biology of most Pallopteridae species remains unknown” (p 339).

“The truth, however, is that we know almost nothing about the life histories of these bizarre flies [Ctenostylidae]” (p 340)

“Nothing is known about the biology of this group [Nothybidae]” (p 348)

“Despite a worldwide distribution, with about 140 known species spread over every zoogeographic region, not much is known about asteiid biology.” (p 363)

“Nothing is known of the biology of the Neotropical dwarf fly genera [Periscelididae]” (p 365)

The quote list above is not comprehensive, but rather a sampling to show some of the many groups of flies that are mysterious despite their ubiquity in some cases. I don’t want the quotes above to be taken as evidence that the book contains little in the way of information on the flies of the world, seeing as so little is known overall. On the contrary, this volume is chock-full of biological details found nowhere else except the specialized literature and I found myself blown away by many intriguing and fascinating descriptions of fly families and subfamilies. Below are a few of the more interesting groups I had never encountered before reading through this book.

Frog midges (Corethrellidae) are attracted to singing frogs where the females feed on the frog’s blood. Some Phorid flies lay their eggs inside ants, where their larvae consume the ant’s head from the inside. After feeding within, the larvae decapitate the ants and pupate within the armored shelter before emerging as adult flies. These flies are known as ant-decapitating flies, and there are more than 300 species of them in the genus Apocephalus. Vermileonidae is a family of flies known as “wormlions” which are essentially the antlions of the diptera, their larvae constructing cone-shaped pits to trap wandering insects for prey. The Fergusoninidae is a family of flies that “develop only in galls induced by a specialized and codependent group of nematodes” (Marshall 2012, p 366).

Probably my personal favourite are the smoke flies. The smoke flies, platypezid Microsania spp., are attracted to fires (even campfires) but are rarely seen elsewhere. The smoke fly swarms are often followed by the predatory empidid dance fly Hormopeza which “seems to be a specialized predator of smoke flies. Like Microsania, the smoke dance flies are rarely seen except when they appear in plumes of smoke.” (p 298). I feel like the smoke flies, a group of species that can be attracted to something as common as a campfire, and yet are known from basically nowhere else (and thus poorly understood biologically) perfectly encapsulate the mystery and wonder of flies that I have gained from reading this book.

All of this fascinating information is found within the comprehensive and authoritative text, and after going through family by family in this fashion, each chapter in the “Diversity” section has a “photographic guide” portion which covers representatives of most subfamilies with further notes on natural history and significance of genera pictured. The scope of the pictures is mind-boggling and further bring home the diversity of flies, as well as their surprising beauty.

Transverse-banded Flower Fly (Eristalis transversa), photographed in my backyard, September 2018.

The final, shortest section covers collecting, preserving and identifying flies, and contains notes for those interested in starting insect collections of their own (as in, pinned specimens) as well as keys for identifying the major fly groups.

I can honestly say that if this book were published with only the text portions I would buy it because the text is just that valuable in overviewing the enormous diversity of the fly families. And I can also say that if this book were published with only the pictures and captions, I would also buy it for the incredible amount of biodiversity on display, captured in wonderful images of flies from around the world.

I cannot recommend this book highly enough. If you are an insect enthusiast, if you are at all interested in the diversity of life and if you enjoy gasping at revelations about the tiny wonders that flit around the world you have to read this book.

Parasitic Plants and other Non-Fungi (NFN Fungi Hike Part 3)

Last August, I went on a hike in Backus Woods with the Norfolk Field Naturalists to identify and photograph fungi. For the first two parts of the observations I made during the hike, see Part 1 and Part 2. My two previous posts covered all of the fungi (and several interesting non-fungi including wood frogs and fungus weevils) that I photographed and described some of their interesting biologies and ecologies. This final post is a roundup of the non-fungi observations I made during the hike.

You would be forgiven for thinking that this next observation also represented the fruiting body of a fungus. Instead, this drooping white organism is actually a plant without chlorophyll (and thus without the colour green and without the ability to capture light from the sun and turn it into sugar). Ghost Pipes (Monotropa uniflora) are parasitic plants, which feed indirectly on the roots of their host trees via underground fungi that attach to the roots in a mycorrhizal relationship (Runtz 2020). The flower heads droop, and give this strange flower its name of “pipe” but when they are pollinated (by bees usually) they will raise their flowers straight upward (Runtz 2020).

Some more traditional plants (you know, ones that are green and perform the magic of photosynthesis) were also spotted along the trails. I learned that the bright red clusters of berries were the ripened fruits of George-Michael-in-the-Banana-Stand (Arisaema triphyllum)*. Besides the red berry clusters, we also saw representatives with green berries that hadn’t ripened yet. Although they may look edible, these red berries contain high levels of oxalic acid and cause painful burning in people that eat them… although apparently white-tailed deer, wild turkeys and wood thrushes will eat them and be fine (Holland 2016).

*more traditionally, the common name is Jack-in-the-Pulpit and most people probably know it by this name, but I couldn’t resist using the new common name proposed by The Field Guides Podcast (for my review of the Field Guides Podcast go here)

Another red-berried plant was a new one for me: Partridgeberry (Mitchella repens). These red berries are edible, but apparently tasteless. The flowers are pollinated by bumblebees and as the name suggests the berries are consumed by ground-birds (such as grouse and turkeys), but also by skunks and white-footed mice (Hayden 2012). You would think that partridges would eat these berries… but we don’t have any partridges in North America, and this species only grows here… so here we have a very useless common name.

Partridgeberry growing and spreading through the leaf litter.

Two other wildflowers added colour and beauty to our hike: Spotted Jewelweed (Impatiens capensis) and Great Blue Lobelia (Lobelia siphilitica). Spotted Jewelweed is pollinated mainly by hummingbirds and bees, while the Great Blue Lobelia is pollinated mostly by bumblebee (Eastman 1995). I unknowingly captured this interaction between Ruby-throated Hummingbirds and Spotted Jewelweed in the past, so I’ve included a picture here.

A few interesting arthropod encounters also enhanced the hike. An American Giant Millipede (of the Narceus americanus complex)* was found in curled defensive posture. 

*the complex refers to the fact that this “species” is actually made up of many species that may be extremely difficult to distinguish

American Giant Millipede in defensive spiral. I didn’t mean to disturb you!

On the way out of Backus Woods, I spotted some speedy insects scurrying across the sands and gravels of the path, those predatory jewels known as Tiger Beetles (Cicindelinae). The two species that I spotted and photographed were the Punctured Tiger Beetle (Cicindela punctulata) and the Big Sand Tiger Beetle (Cicindela formosa). 

I hope you enjoyed this tour through Backus Woods with a focus on Fungi. I know I learned a lot and am excited for future outings with the Norfolk Field Naturalists!

Fantastic Fungi (NFN Fungi Hike, Part 2)

Back in August, I went for a hike with the Norfolk Field Naturalists to search for Fungi to photograph (see Part 1). Along the way, I encountered many organisms both fungal and not-so-fungal.

One non-fungus was photographed perched atop some fungi on a log. The creature was a Marbled Fungus Weevil (Euparius marmoreus), which feeds on polypore fungi (Marshall 2018).

Marbled Fungus Weevil, the only time I used my macro lens on this entire hike.

The next observation brings us back to the focus of the hike: Fungi. This strange spherical object covered in a lacework pattern is the fruiting body of an Earthball (Scleroderma). These fungi actually interconnect with tree roots to form mycorrhizal associations, benefitting the trees and the fungus (Stephenson 2010).

Earthball (Scleroderma), the fruiting body of a mycorrhizal fungus.

Another spherical object caught our eye while hiking through the woods: an Oak apple gall. This particular one was caused by Amphibolips cookii, a Gall Wasp feeding within the bud of a Red Oak (Quercus rubra). The bud developed into this spherical gall, while the larva fed within and then this “oak apple” detached and fell to the forest floor, and I guess the adult wasp has already left this gall behind? I don’t know, it was very difficult to find any information about this species or gall wasps (Cynipidae) in general despite them being fascinating insects (what I did find was a website that contains some information: gallformers.org, a site worth checking out if interested). I have a particular fondness for galls caused by insects… they’re plant growths that create particular species-specific patterns for the insects that inhabit them… what’s not to like?

Oak Apple Gall (caused by Amphibolips cookii).

Further down the trails, we encountered some classically shaped mushrooms unlike the more bizarre (in my opinion) Earthballs (Scleroderma). A member of the genus Oudemansiella and a member of the genus Russula.

Oudemansiella mushroom.

Russula fungi are ectomycorrhizal, meaning that their underground mycelia (the major part of the fungal body) connect with roots of trees and other plants to transfer and exchange nutrients (Stephenson 2010). 

Russula mushroom.

Some of the most common fungi that we spotted were associated (as many fungi are) with dead or dying wood. Fungi that feed on dead or decaying material are known as saprotrophs. Orange Mycena (Mycena leaiana) were spotted multiple times throughout our excursion and I have to say they might be my favourite fungi that we found simply for aesthetic reasons. The beautiful colour of their fruiting bodies really brighten up the dead logs and fallen trees in the forest. 

Another wood-feeding saprotroph we found often is known as the “Oyster Mushroom” (Pleurotus), apparently because of its fishy smell (which I couldn’t detect, perhaps it needs to be cooking?). These are very commonly collected for humans to eat.  As mentioned above, the Oyster Mushrooms feed on decaying and dead wood, but they also feed on microscopic creatures called nematodes. The details of the interaction are incredible. The Pleurotus fungi has special cells among its hyphae (the underground components of the fungal mycelium) which produce a toxin that paralyzes nematodes. After contact, the nematodes continue moving (usually much slowed, and erratically) for 30 seconds to several minutes before succumbing to the paralyzing toxin. The immobilized nematodes are then attractive to fungal growth from the Pleurotus mycelium, which produces hyphae that thread through the material (usually dead wood or soil) to reach the nematodes and enter their bodies. These fungal threads break the nematode down, consuming it while it is still alive but paralyzed. If you’re interested in more of these details, you can read the full paper where it’s described (Barron and Thorn 1987) here: https://cdnsciencepub.com/doi/10.1139/b87-103.

Pleurotus mushroom, unassuming destroyer of wood and nematodes.

There were a couple of other saprotrophic fungi found feeding on logs during the hike. Resinous Polypore (Ischnoderma resinosum) has a strange texture that was unexpected, though appearing like tougher shelf fungi it was actually quite soft and pliable. Our guide likened it to the feel of a donut and I can attest that this assessment is bizarrely valid.

Resinous Polypore, strangely soft and light.

Not all fungi grow on logs however, and there are several interesting groups that are very easy to miss. One colorful but tiny fungus is the Red Chanterelle (Cantharellus cinnabarinus) which grows singly or in clumps and is connected to the root systems of trees in yet another mycorrhizal relationship.

Red Chanterelle peeking out from the leaf litter.

Two representatives of a more bizarre ground-sprouting group would have been easily missed. This group is known as the “Earth-tongues” (Family Geoglossaceae). You can (perhaps unfortunately) see their resemblance to strange tiny tongues protruding from the soil. Our guide was quite excited to have spotted the dark Earth-tongues (identified via iNaturalist as Trichoglossum because of the tiny hairs) because they would be very easy to miss.

That brings us to the end of the fascinating fungi that I spotted on our hike! It is not the end however of the non-fungal sightings. A few more of those to review in the final part of this ‘series’.

Freezing Frogs and Fascinating Fungi (NFN Fungi Hike, Part 1)

I recently joined a local group of nature enthusiasts known as the Norfolk Field Naturalists. My very first outing with the Norfolk Field Naturalists was a hike through the Backus Woods Conservation Area with a local Fungi expert Leanne Lemaich. The hike was rewarding for the opportunity to meet up with others who share my passion for learning about the nature around us, and I learned a lot about the various fungi in the area. I used my camera extensively, capturing fungi and non-fungi (some new ones for me!) as you’ll see below. All in all, it was a great experience despite feeling as though I singlehandedly sponsored the next generation of mosquitoes with most of my blood supply…

Let’s begin with a brief primer on Fungi, because that’s how our hike began as well. Despite being classified so often with plants, fungi are actually more closely related to animals, but in any case they are neither. Unlike plants, fungi can’t produce their own energy, ie. they don’t contain chlorophyll, the pigment that makes leaves green and captures energy from the sun to create sugars/carbons (the incredible process known as photosynthesis). Instead, fungi feed on other organisms just like all animals do. Many fungi feed on dead organisms (termed saprophytic, or saprotrophic), but there are also many that feed on or within living organisms and still others form symbiotic relationships (which can grade into parasitism… the difference between symbiosis and parasitism is actually very grey-shaded). Although most of a fungus is composed of tiny threads that grow and proliferate out of sight, there are extraordinary structures that appear for reproductive purposes and these are collectively called “mushrooms”. I like to think of mushrooms as the equivalent of flowers, because they’re the visible part that facilitates reproduction just like the flowers in plants (via insects/other organisms/wind/rain/other weather processes in both instances). Now that we have a (very) basic idea of what fungi are, we can move onto some of the particular ones I observed and photographed on this hike, as well as many non-fungi spotted along the way!

Our first fungal find was a Bolete (Family Boletaceae), and the first incredible fact that I learned was that this mushroom couldn’t be identified without a… taste test. We hear so often about the dangers of foraging for mushrooms, because there are poisonous lookalikes to edible species and such, that I was very intrigued to learn that some mushrooms are identified by taste. Of course, I will reiterate the warning you will hear literally everywhere mushroom foraging is mentioned (and for good reason): DON’T EAT MUSHROOMS IF YOU’RE UNSURE OF THEIR ID.

Unidentified Bolete emerging from the leaf litter.

Next up was a familiar species even to me, a comparative novice when it comes to fungal identification: Turkey-tail (Trametes versicolor). This common species feeds on dead wood, and contains enzymes able to break down cellulose and lignin at the same time (Stephenson 2010). These are the two main components of plant cell walls, and are notoriously difficult for animals to digest.

Turkey-tail fungus growing out of the side of a log.

Several times during the hike, we came upon Coral fungi, which unsurprisingly resemble underwater corals in their branching structures. Our guide identified some of these as possible Ramaria species, but she also pointed out a false coral (Sebacina schweinitzii).

This next unassuming organism isn’t a fungus, but rather a strange living thing called a slime mould, specifically the Dog-vomit Slime Mould (Fuligo septica). The Dog-vomit Slime Mould is part of a group known as the plasmodial slime moulds, the Myxomycetes. Myxomycetes have a complicated and confusing life cycle. They have two feeding stages: the first consists of single cells which move and feed within their environment like amoebae (Stephenson 2010). These single cells reproduce and form a plasmodium, which is still a mass of what might be termed a single cell because it doesn’t have any cell walls, but it contains many nuclei (Stephenson 2010). In both of these stages, myxomycetes usually feed on bacteria or fungi that they encounter. I believe the Dog-vomit slime mould that I encountered was in this plasmodium stage, possibly preparing for its ‘final form’ which would be the production of fruiting bodies which would disperse tiny spores to start the process all over again (Stephenson 2010). Bizarre organisms… aliens of the forest floor.

Dog-vomit Slime Mould.

We encountered one other species of slime mould during the hike which was much more aesthetically pleasing than the one named after dog-vomit… the Red Raspberry Slime Mould (Tubifera ferruginosa).

Red Raspberry Slime Mould. For scale, note the blurry Harvestman (Opilione) to the right of the Slime Mould fruiting bodies.

While stepping through the undergrowth to approach some fungi, I disturbed some hopping amphibians at my feet. At first glance, we thought they were regular toads (ie. Eastern American Toads: Anaxyrus americanus) and some of them were, but one stood out as something distinctively different. This frog was one that I had never seen before, though I had heard its strange “quacking” calls during hikes in the past: a Wood Frog (Lithobates sylvaticus). Part of the reason I haven’t seen them is their superb camouflage, which consists of not only a generalized leaf-litter brown pattern. Wood Frogs also exhibit background matching: changing their skin to match their surroundings. While in breeding ponds in the Spring they are darker (and thus match the water more closely), and assume a lighter coloration when among the generally lighter leaf litter of their environment for the rest of the year (Wells 2007).

Wood Frog among the leaf litter. Pretty well camouflaged, I must say.

One of the facts that always comes to the fore of my mind when I think of Wood Frogs is not their strange call, or their camouflage, but the fact that they can tolerate being frozen. Wood Frogs, at the onset of winter, have physiological mechanisms that promote ice formation between their cells, and prevent ice formation within their cells. What this response amounts to is well described by Bernd Heinrich in Winter World: “the frog is frozen solid except for the insides of its cells. Its heart stops. No more blood flows. It no longer breathes. By most definitions, it is dead.” (Heinrich 2003, p 174). The incredible part of the story is that the Wood Frog is not dead, but rather will await the arrival of spring beneath the leaf litter and revive during warmer temperatures. They can in fact revive from frozen to active within a single day (Harding and Mifsud 2017). As Heinrich says, Wood Frogs are “biological marvels that challenge the limits of our beliefs of what seems possible.” (Heinrich 2003 p 175).

Another Wood Frog spotted during the hike.

As I mentioned above, Wood Frogs weren’t the only anurans (frogs and toads) spotted during our hike. On several occasions, we observed American Toads (Anaxyrus americanus) on the forest floor. I don’t have anything particularly interesting to say about toads right now, besides that they are amazing to look at if you take the time. Below are pictures of a particularly large toad (about the size of my fist) and a smaller toad, which was captured from an unusual angle. The angle really makes me reassess toads in general but maybe that’s just me.

For no particular reason, I’m going to pause here for Part 1! Keep an eye out for future parts, because during this hike I spotted many more fungi, and some more non-fungi as well.

Podcast Review

The Field Guides

I’ve started listening to podcasts over the last few years, and I especially enjoy a podcast that has a good balance of entertainment and education. That description is perfect for one of my favourite podcasts: The Field Guides. This podcast first started in September 2015 and now has over 60 episodes released so if you’re just tuning in now you have plenty of excellent content to catch up on. The presenters’ goal is to bring a trail experience every month or so, though that doesn’t always happen which I think we can all understand. Life happens. Even so, they have released quite a few episodes and they’re usually about an hour long each. Some episodes are split into two parts, with each part being about an hour long. Each episode focuses on a nature topic (or the occasional nature location, such as their tour of the Roger Tory Peterson Institute). The topics range from Goldenrod Galls to Bird Banding. Sometimes they focus on a particular species, such as the Purple Pitcher Plant, and sometimes they focus on a broader natural phenomenon such as the relationship between Ants and Plants or Fall Colours.

Here’s a Goldenrod Gall (spherical swelling on the stem), which I photographed in Macgregor Provincial Park, Ontario. The various galls that form on Goldenrod (Solidago) are the topic of the first episode of The Field Guides.

I like that whatever their topic of choice is, Bill and Steve delve into it with real research from papers published in scientific journals or credible book sources. I appreciate the level of detail that is provided on each given topic as it’s not all surface-level same-old natural history facts. This is especially true in some of the two-part episodes as the extended time allows for even deeper exploration of a nature topic. With the use of scientific papers and research, there can be some discussions that are difficult to follow because of scientific jargon or complex topics, but for the most part they bring out the significance of the science and explain in a way that doesn’t leave one struggling to keep up.

Besides discussing a nature topic or species (which would be good enough in my opinion), Bill and Steve also hit the trail in various locations mostly in New York State. There is an episode about Spruce Grouse where they traveled to Algonquin Provincial Park in Ontario which was especially exciting to me as I love Algonquin Provincial Park. This was the only location familiar to myself, but if you’re in New York state I’m sure you’ll recognize many of the trail locations they visit. Despite walking around through leaf litter and beside streams, the audio experience of the hiking enhances the listening experience rather than detracting from it. Rare is it that the sound of wind on the microphones or crunching footsteps overpowers the discussion or intrudes in any sort of negative way. Instead, the sounds of birdsong (some recognized by me, some unfamiliar) and the calls of amphibians add a lot to the ambience.

I have never photographed a Spruce Grouse, but here’s a relative I photographed in Algonquin Park: a Ruffed Grouse (Bonasa umbellus).

As I mentioned at the beginning of this post, for a podcast to be especially enjoyable for me, it needs an entertainment factor. In this case, The Field Guides Podcast delivers with sarcasm throughout (often by Steve, but Bill gives his fair share as well), and humorous anecdotes or comments. I think one of my favourite jokes was the two of them coming up with alternative common names for Jack-in-the-Pulpit because common names can be whatever you want them to be. Some of their excellent suggestions were “Ripley-in-the-Power-Loader” and “George-Michael-in-the-Banana-Stand”. I will mention here that their humour is enjoyable for an adult audience, as there are occasional jokes and comments that are inappropriate (or indecipherable) for younger audiences. They even have a two-part episode which has the Explicit tag called “Eat Sh*t and Live, Bill”, all about coprophagy (animals/plants eating poop). The episode was fascinating, but just in case any teachers wanted to play this podcast for younger students it does contain some adult humour.

In summary, The Field Guides is a must-listen if you’re interested in Nature and Science. I have spent many hours of enjoyment laughing at the jokes and sarcasm and learning a lot about the animals and plants and nature phenomena that are all around us. Give it a listen!
