Blogversary

Happy 3rd Birthday, Norfolk Naturalist!

3 Years of Blogging at norfolknaturalist.ca have passed and it’s time to look back at the past year of my naturalist adventures and reading/writing. Let’s go!

Look closely and you’ll see one of my most amazing bird sightings this year, a stealthy American Bittern (Botaurus lentiginosus) in Long Point, May 2022.

Starting off this past year of blogging was my introduction to a series of posts highlighting my Top 20 Nature Photos 2013-2020. I explain in that post why I chose that date range and how I chose the photos. When posting the first one, I ended up writing more than I expected about the species, in this case the Pale-painted Sand wasp (Bembix pallidipicta). I wrote several more entries in this series through the following months: (Moose (Alces alces) family, Canada Jay (Perisoreus canadensis), Common Five-lined Skink (Plestiodon fasciatus), and in September I published entry 5: Robber Fly (Neoitamus orphne) hunting Queen Ant (Formica novaeboracensis). I was originally planning to post them all in a row for my first 20 posts of this past blogging year… but oh well. I promise I am still working on the other 15 posts and I think the wait will be worth it for the species to get their proper spotlight.

A close encounter with the Heron I usually see, the Great Blue (Ardea herodias).

In March of this year, I reposted my original blogpost (Cryptic Caterpillars) from my tumblr blog (anorfolknaturalist.tumblr.com) because I hadn’t finished any other blogposts for the month and I also want to repost all of my original tumblr blogposts on this website, with occasional minor edits and updating. I reposted another tumblr post in May (MacGregor Point Observations (May 2018)) And in October, I reposted yet another, this time with a Halloween theme: Eaters of the Dead.

In April I was amazed and delighted to find that Ravens were nesting on my parents’ property (specifically on their silo), so I wrote a post about my observations and their significance.

Great Egret (Ardea alba), in Long Point, September 2022.

In June I went to see Jurassic World: Dominion, the latest film in the Jurassic Saga. I wouldn’t say it’s a great film, but I did really enjoy it, especially with the theatre experience. I wrote a blogpost about my personal interactions with the Jurassic books/films/videogames and some paleontological things because they were on my mind a lot at the time. You will see that some of the books I read over the blogging year (overviewed below) were also inspired by my dinosaur obsession which comes and goes quite often.

Some of my most exciting observations this year were of birds that I encountered in Long Point. And some of the most exciting birds were members of the Heron Family (Ardeidae). Usually I see and take photos of Great Blue Herons (Ardea herodias) which is great but it was amazing to encounter several other members of this charismatic group of birds this year. My close encounter with a Green Heron (Butorides virescens) was so striking that I wrote it up into a blogpost: A Green Heron Stalks the Shallows.

Two other blogposts feature some of my Long Point observations. One is sort of a tour through a variety of observations I made during March 2022: Bullfrogs and Buffleheads. Another is more like the Green Heron post mentioned above, as it focuses on a specific bird that caught my attention. In this case, it was the Green-winged Teal (Anas carolinensis): The Teal Tale Teale Told.

During August, we took a trip to one of my favourite places: Algonquin Provincial Park. While there, I made some nature observations and took some photos, sharing them in my blogpost here: Algonquin in August.

And that wraps up my writing this year. Below, we will take a tour through the books I read this past year (that are nature/science related) and discuss them briefly.

Nature’s Year: Changing Seasons in Central and Eastern Ontario, by Drew Monkman:


Although the book is not directly focused on my local area (Norfolk County falls outside of the books focal range), the close proximity of the areas documented mean that many of the natural phenomena described within are of relevance to the seasons around me as well. I really appreciated the layout of the book. Each month is divided into sections based on organism type: “Plants and Fungi”, “Reptiles and Amphibians”, “Mammals” and so on. Beneath each of these sub-headings, interesting happenings are described, some in point-form and others in detail (full page or two). It was great to witness the natural events mentioned in the book, to read along as each month progressed as I did in 2021. Reading the book through the year prepares your mind to see the natural events it describes. An advantage of the layout is that it also works well as a reference because you can flip to a certain month and type of organism to see what notable species or events are occurring.


Biodiversity in Dead Wood, edited by Jogeir N. Stokland, Juha Siitonen, and Bengt Gunnar Jonsson:


A new favourite book of mine, this volume opened up the mysterious biome of decaying wood and explored the diversity of life within, from bacteria to birds. The interactions of organisms with each other and their environment is the heart of ecology and it’s clear from my reading that species are interconnected in fascinating and complex ways.


Spider Communication: Mechanisms and Ecological Significance, edited by Peter N. Witt and Jerome S. Rovner:


The title of this book drew me to it as I am always fascinated by animal behaviour and Spiders seem to me unlikely subjects of a volume dedicated to communication. Reading the book offers a new perspective on spider interactions with each other through their silk and body movements and even acoustics! They also communicate with predators and prey,

Hedgehog (Collins New Naturalist), by Pat Morris:


I didn’t really know anything about Hedgehogs before reading this book. And there was no need, as this volume summarizes in entertaining fashion most anything anyone would want to know about British Hedgehogs.


The Encyclopedia of Animals: A Complete Visual Guide, edited by George Mckay:


I read through this book slowly, as it is not really meant to be read straight through. This book serves best as a flip-through book, showcasing the diversity of animals around the world. The illustrations are at times a bit strange (I believe many are stock illustrations) and don’t seem to match with the animal they depict, but others are quite beautiful and the diversity they portray is fun to look at. The text is very cursory as would be expected with a popular “flip-through” tome like this. My major gripe with this book is something I used to harp on about all the time growing up as an insect enthusiast: Invertebrates are barely represented. Mammals get the majority of pages devoted to them, and Birds are close behind. Mammals and Birds are fascinating, and far more diverse than one would assume if you have only watched nature documentaries (which focus on the same set of species rather than showcasing the variety that are actually out there). Even still, they are a fraction of the diversity of the animal kingdom, which is more appropriately ruled in species numbers by the Arthropods or Mollusks. Despite this (a very common problem in overview books) I really had fun slowly reading through this book, taking in a page or so of variety a day. I wouldn’t say it is the best or most comprehensive of animal encyclopedias, but it serves as a good introduction as long as one is well aware of the classic hairy or feathered vertebrate bias.


British Tits (Collins New Naturalist), by Christopher M. Perrins:


British Tits have always struck me as beautiful chickadees, which indeed they are. I was always jealous of Britain having the wonderful cheery birds I know from my backyard, but with more vibrant colour. Tits are fascinating birds, with life histories and behaviour to match their beautiful exteriors. This book was an excellent overview of the species of Parulidae that occur in the British Isles.

Dinopedia, by Darren Naish:

A compact and great little book filled with tidbits about the history of dinosaur research, some of the paleontologists who conducted said research or influenced the field of dinosaur study, and brief summaries on dinosaur groups. My personal tastes lie with this last group of entries, but each entry was interesting in its own way, supplying concise facts and summaries and highlighting areas of interest within the world of dinosaur research. I greatly enjoyed the illustrations by the author which really enhance the book.

Reef Life: A Guide to Tropical Marine Life, by Brandon Cole and Scott Michael:


A delightful photo-focused tour through the world of coral reefs and tropical sea life. The focus is on fishes, while smaller sections describe and display some representative invertebrates. Styled something like a field guide, but with plenty of ecological and biological information throughout, this book gives a taste of the diversity of coral reefs and the interconnected lives of the species that create and depend on them.

Bat Ecology, edited by Thomas H. Kunz and M. Brock Fenton:


Bats are fascinating, and I learned a lot about them from this book. Because of the book’s focus on Ecology, there was no real overview of Bats as a group which would have been nice for myself to have some sort of general idea before diving into specifics. Not a fault of the book, just something to note if you’re unfamiliar with bats from a scientific point of view. The chapters are each written by different authors and cover a wide range of topics, and as such there were excellent and enjoyable chapters (for myself the chapter on Roosting sites and the chapter on Pollination were particularly fascinating) and some chapters that were less so. Not a fault of the book, but my personal point of view and knowledge base left me struggling through the chapters on Sperm Competition and Patterns of Range Size. Those two chapters in particular felt like specific scientific studies rather than reviews of a subject area which the other chapters felt like. So, while mixed, the interest I have in Bats has certainly been increased and I have certainly learned a lot about some of the diverse ecologies that bats have around the world, while still wanting more.

This Day: New and Collected Sabbath Poems 1979-2012, by Wendell Berry:

In the preface, Wendell Berry remarks that the poems should be read outside in similar circumstances to when they were written. And I originally envisioned doing so. When I began to read them in very different circumstances, I found that instead of diminishing the power of the poetry by contrast, the poetry brought the beauty and wonder of nature into my less-than-ideal setting (usually indoors in winter or at work).

Owls of the Eastern Ice: A Quest to Find and Protect the World’s Largest Owl, by Jonathan C. Slaght:


Although I will always want a book like this to have more focus on the animals themselves (in this case Blakiston’s Fish Owls) I thought this was a very interesting listen (I had the audiobook). Lots of adventures and misadventures in the Russian wilderness, as well as strange and intriguing people that the author encounters. And there was quite a bit about how the field research actually worked and the sorts of things I really was looking for: info and descriptions of the wildlife encounters including the focal species. Overall, a good read about an animal I didn’t know much about before and the efforts to research and protect it.

Dinosaurs Rediscovered: The Scientific Revolution in Paleontology, by Michael J. Benton:

I picked up this book from the library, inspired by my recent viewing of Jurassic World: Dominion, and found this book to be a mixed bag. I enjoyed some of the stories behind discoveries or changes in perspective on dinosaurs and their world… but I found other such stories to be irrelevant or out of place. In general, the flow of the book was a bit haphazard. The information within sated my appetite for dinosaurian (and some non-dinosaur) biology and ecology temporarily and I enjoyed the illustrations and figures.

Ant Ecology, edited by Lori Lach, Catherine L. Parr, and Kirsti L. Abbott:


Because this is an edited multiauthored volume, it becomes difficult to review the whole, as chapters are written with different topics and by different people. Overall, this was an interesting look at more recent ant research (20 years more recent than my other source for ant knowledge: The Ants by E. O. Wilson, written in 1990). There is a heavy conservation and practical (invasive ecology) focus to the book which may attract workers in these fields.

The Amber Forest: A Reconstruction of a Vanished World, by George Poinar Jr. and Roberta Poinar:


Fascinating gallery of ancient organisms preserved in amber of a particular age and location. Mostly insects and other arthropods which is fine by me, I enjoyed the overview of insect relationships and such that were covered alongside the representatives of the different groups found in amber. The format was a little strange and took some getting used to, I feel like there could have been a better way to present the images and the text but I don’t know, felt a little awkward flipping back and forth throughout reading. All in all, very interesting especially if you like insects and fossils.

A Naturalist At Large, by Bernd Heinrich:


A fun tour through various natural history topics. Bernd Heinrich is curious about the nature he observes and doesn’t take things for granted and by doing so, he discovers by bits and pieces, fascinating natural history stories. I especially liked the chapters focused on birds or insects, perhaps due to my own interests and knowledge but I think perhaps it is because those were Bernd Heinrich’s research focuses as well and his insight there was thus enhanced.

Biology and Conservation of Wild Canids, edited by D. W. Macdonald and C. Sillero-Zubiri:


A great review of Canid Conservation around the world. The case studies were interesting snapshots of species under investigation from Grey Wolves of Isle Royale, in Lake Superior, to the Blanford’s Fox in the deserts of the Middle East. While not comprehensive on the biology/ecology of canids (some species didn’t even get a case study chapter such as Bush Dogs), this was an excellent primer on the diversity of species and challenges in the canid research world.

Are We Smart Enough to Know How Smart Animals Are?, by Frans de Waal:


A book aimed at tearing down the division between human and “animal” cognition. Presents a wide array of anecdotes and experiments that demonstrate that human thinking is a matter of degree and not a separate category altogether from the millions of other species on this planet. I was a bit disappointed that the author focused mainly on chimpanzee research (his own specialty) but this served to really break down the idea that human thinking is a different sort from other species as chimpanzees display many of our ways of thinking that humans previously considered unique to our species. I would have loved to read more about cognition in diverse species and phyla, the one section on invertebrates was intriguing but all too short, but all in all the book presents its arguments well, and discusses the history of thinking about animal thinking in an interesting and thought-provoking way.

That concludes my writing and reading overview for the past blogging year! Stay tuned for more nature sightings, observations, photos and natural history!

5. Robber Fly Hunting Queen Ant

Subject: Underworld Robber Fly (Neoitamus orphne) and New York Carpenter Ant Queen (Camponotus novaeboracensis).

Location: Algonquin Provincial Park.

Date: July 2017.

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

The Story Behind the Shot: Every ant colony, each civilization in the soil, has to begin with a single type of individual: an ant queen*. Queens are special individuals, easily separated from the workers by their wings (at this preliminary stage) and their relatively large size. While camping in Algonquin during the summer of 2017, my campsite was in the path of dozens of queen carpenter ants. I watched as several different individuals wandered through the pine needles and discarded their wings. I had also been separately observing a large robber fly that had taken up residence on my camping table, using the surface to survey for potential prey. At some point the robber fly descended upon one of these ant queens and I was lucky enough to spot the unfortunate queen and its fortunate hunter.

*nature never lets me get away with generalizations… I would have liked to say, for the drama, that every colony begins with a single individual, but that isn’t true at all. There are many species of ants that create new colonies with multiple queens as a rule, and many times groups of workers accompany the queen (or queens). One of the most famous of these species is the Southern Fire Ant Solenopsis invicta, but dependent colony founding (that is, colonies that begin with a queen dependent on workers as opposed to independent colony founding) is widespread in ants. As in all things in the natural world, the picture becomes increasingly complicated, the more we know (Peeters and Molet 2010).

The Story Behind the Species:

Part 1: New York Carpenter Ant (Camponotus novaeboracensis):

The ant queens that I saw that day had emerged from a colony in what is termed a mating swarm. Multiple colonies in the area, triggered by the weather conditions must have swarmed at the same time, winged ants filling the air and meeting to mate. The males of these ants die soon after mating, but the queens will live for several years if they can establish a colony. The vast majority of ant queens will also die during this mating flight. Holldobler and Wilson (1990) describe this well: “It follows that the brief interval between leaving the home nest and settling into a newly constructed nest is a period of intense natural selection among queens, a dangerous odyssey that must be precisely timed and executed to succeed.” After mating, the ant queens descend to the earth and never leave it for the air again, removing their wings and absorbing the flight muscles within to provide the nutrients for their first batch of eggs. Camponotus novaeboracensis prefers nesting in dead standing trees or fallen logs or stumps, but they are occasionally found nesting under rocks or cow dung (Ellison et. al. 2012). Contrary to what you may think, carpenter ants (the genus Camponotus) don’t consume wood for food, instead carving into decayed wood in order to create a nesting site. One of their major sources of food is actually honeydew from Homoptera (true bugs such as leafhoppers, treehoppers and aphids), but they also collect sap and hunt insects and will scavenge on dead vertebrates as well (Hansen and Klotz 2005).

Foraging as an ant worker is dangerous, there are many other creatures foraging that would hunt down ant workers, and that’s ok for the colony because each worker is just one small part of a larger whole. Camponotus novaeboracensis colonies can contain almost 9000 workers (Hansen and Klotz 2005), but usually only a single egg-laying queen*. So workers can be lost, and the colony continues, but the queen is important so the colony can begin. If she is lost before she can find a nesting site, as in my observation here, there can be no colony of thousands.

*Akre et. al. 1994 report that C. novaeboracensis colonies rarely have more than one queen, but it does happen.

Part 2: Underworld Robber Fly (Neoitamus orphne):

Robber flies are incredible hunters, swooping out from perches on branches or twigs (or in this case, camping tables) to pounce upon insects and stab them with their powerful piercing mouths. There are over 7000 species of Robber Fly (members of the family Asilidae) worldwide (Marshall 2012). Neoitamus orphne has a specific name, orphne, which refers to a spirit of Greek mythology that lived with Hades in the Underworld, and is sometimes referred to by the name “Styx”. I love the idea of this fly being named after a spirit of the Underworld, as this robber fly must send many souls of insects to Hades on a frequent basis. The individual pictured is a female, which will use that long tubular abdomen to lay eggs inside flower heads or leaf sheaths. The larvae then hatch and drop to the ground, where they will hunt down soil-dwelling invertebrates presumably (Marshall 2012). I say “presumably” because I don’t think anyone knows for certain what this species of robber fly eats as larvae but robber fly larvae are predators and this genus has larvae that live on or in the ground so it makes sense.

My photo captures a battle between two mother insects, one which has the potential to generate a social colony of 9000 worker ants, another which lives a solitary life snatching prey out of the air.

Nature Observations Tumblr Repost

Cryptic Caterpillars

In the interests of my own personal goals to post at least once a month, I’m going to re-publish my very first post on my first iteration of the Norfolk naturalist blog, which was on tumblr. I’m planning to re-post all of my articles that I wrote on my tumblr on this site at some stage (possibly with some slight updates/alterations) since I would like them all in one place, and my own website seems like the best place to have that. So here is my first Norfolk Naturalist post, originally published on my tumblr back in 2018 (over 4 years ago!):

While walking the trail near my house, I spotted a twig in an unlikely spot. Instead of forming the final split of a growing or dead branch, the tiny twiglet (just larger than my fingernail) was jutting out into the air from the railing of the bridge. Something strange was going on. On closer inspection, it turned out not to be a twig at all. Rather, a caterpillar had chosen a poor and rather conspicuous spot to hide.

If this caterpillar had chosen a better location, it surely would have fooled me. Even where it was, it was extremely difficult to spot. The coloration and shape of its back was a perfectly mottled gray-brown, and its posture was that of a twig. It was thin-bodied and elongate, only about a millimeter around.

The caterpillar’s odd shape is provided by it having a large space between what are its true legs (the six legs just behind the head) and its ‘prolegs’ which are fleshy stubs coming off of its abdomen. This large space also causes these caterpillars to move in a unique fashion. They lift the front group of legs and extend it forward, reaching ahead and securing themselves there. Then they lift their rear group of legs and move them forward to reconnect with the front legs. Once together, the rear legs hold their place and the caterpillar once more reaches forward with its front legs. This “inching along” process provides this group of caterpillars with their name: the Inchworms (Family Geometridae).

A caterpillar’s main predators are birds which hunt visually. If the caterpillar appears to be something other than a morsel to a hungry bird, then it has succeeded and survived another moment. This type of behavior has a technical name: “crypsis” or “cryptic behavior”, which just sounds amazing. It strikes this cryptic pose when threatened, and so effectively disappears from a hunting bird’s search. I suppose it must have assumed this position when I walked near, thinking me to be hunting it for food. In reality, I was hunting only for a few pictures.

I hope you enjoyed that “repost” from the older version of norfolk naturalist blogging. I promise I’m still working on My Top 20 Nature Photos of 2013-2020 series and I also have several other posts about more recent nature sightings in the works. Hopefully April will be a more productive writing month!

Top 20 Photos 2013-2020

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…

July 2021 Observations Nature Observations

Port Burwell Observations

I recently spent a weekend camping at Port Burwell Provincial Park and took several photos of interesting creatures I encountered there (as I usually do on camping trips). One of the first creatures I encountered was a beautiful Flower Fly which hovered right in front of my face for a few minutes and even landed on my glasses, as well as several times on my hands. My Flower Fly Friend was an Oblique Streaktail (Allograpta obliqua).

Oblique Streaktail Flower Fly which landed repeatedly on my fingers and even on my glasses.

Flower Flies (Family Syrphidae) are wonderfully diverse and easily observed Insects, as they spend time hovering and landing on Flowers for the nectar they contain. In feeding on nectar, these Flies contribute greatly to Pollination, much like their similarly coloured models, the Bees and Wasps. I observed several other Flower Flies during my Port Burwell visit:

Common Flower Fly (Syrphus ribesii).
Mating Pair of Margined Calligrapher Flower Flies (Toxomerus marginatus).

Most people don’t consider Flies beautiful, but that’s because they’re thinking of the House Fly variety, and not the colorful Flower Flies. Another beautiful fly I observed was this Ornate Snipe Fly:

Ornate Snipe Fly (Chrysopilus ornatus). Who says Flies aren’t beautiful?

The Snipe Flies (Rhagionidae) are predators as larvae in the soil where they hunt invertebrates, but as adults don’t seem to feed at all (Marshall, 2012).

Like my Flower Fly Friend, another Insect was quite content to wander over my hands. I’m not sure the exact ID of this Bug (a True Bug, that is a member of the Order Hemiptera) but I’m pretty sure it’s a larval Plant Bug (Family Miridae).

Plant Bug nymph (Family Miridae) on my fingertips.

The little Plant Bug was probably the smallest Insect I took pictures of that weekend. The Largest is much easier to determine, and was clearly this Waved Sphinx (Ceratomia undulosa) which was on the outside wall of the restroom, blending in fairly well with the bricks.

Waved Sphinx Moth blending into a wall.

Another Moth I observed couldn’t be more different from the bulky and camouflaged Waved Sphinx. This bizarre Grape Plume Moth (Geina periscelidactylus) doesn’t even look like a Moth at all because of its oddly shaped wings. 

Grape Plume Moth (Geina periscelidactylus).

The forewing is the brown and white portion with a large notch carved into it from the outside. The hindwing has been transformed into three “plume” structures which resemble black-and-white wire brushes.

One other Moth drew my attention, but this one didn’t have any wings, because it was still in its Caterpillar stage: the Tussock Moth Orgyia leucostigma. These caterpillars have some of the most extraordinary decorations in our area. It’s possible the row of white tufts along their back resemble Parasitoid wasp cocoons in order to avoid subsequent parasitism, but I have no idea where to start explaining the bright orange head or black spiky tufts around its face.

Tussock Moth Caterpillar (Orgyia leucostigma).

It’s well known that caterpillars turn into Moths and Butterflies, but many people are surprised to find that “baby” Ladybugs look quite different from the roly-poly adults. During the weekend, I spied the intermediate stage, the pupa, of a Ladybug stuck to the top of a leaf. Within, a Ladybug larva was being rearranged into the far more familiar form of its orange shielded adult beetle.

Asian Ladybird Pupa (Harmonia axyridis).

There were a number of smaller orange Butterflies flitting about our campsite which were difficult to photograph. This is the best picture I could manage of the upperside wings:

One of this same species (the Northern Crescent, Phycioides cocyta) was resting inside the Dining Tent, allowing me a good photo of the underside of its wings:

The interior of the Dining tent provided many other Insect observations that weekend. I observed this same phenomenon in my own backyard in May of this year. For whatever reason, many Insects enter the tent and then possibly get trapped inside because they have difficulty relocating the entrance (and are drawn to the light visible through the roof of the tent). In any case, it often presents myself with picture opportunities of insects I might not otherwise observe.

Most of the Dining Tent insects were Flies (and these are the ones I got good pictures of):

Rhagio Snipe Fly.
Horse Fly, I believe of the genus Hybomitra.
Crane Fly (Family Tipulidae).

The majority of my observations were of Insects, and this reflects their abundance and diversity well, but I did have a chance to see a few Birds moving through the campsite. Most commonly spotted was a Catbird (Dumetella carolinensis) that seemed to have a particular liking for the berries that grew at the edge of the site. Flitting through the trees occasionally were American Redstarts (Setophaga ruticilla), fabulous black-orange-and white Warblers. Prior to this trip, I thought of the Redstart as a migrant, passing through Southern Ontario in the Spring and Fall. Since seeing it in Port Burwell in July, I have learned that the species breeds across most of Ontario during the summer (Cadman et. al. 1987).

Leafhoppers, Lepidopterans and Longhorns

Common visitors to my backyard (and probably any backyard with any sort of plant life) are leafhoppers (Cercopidae) and I’ve become familiar over the years with a few of my regular visiting genera. This past month I managed to get a really clear picture of Draeculacephala, with its distinctively pointed head.

And this Latalus leafhopper kept flicking its wings around, similar to the Sepsid Flies I’ve seen flashing wings in the sun. Not sure if it was display behaviour of some kind or if it was trying to rid itself of some nuisance. The wing-flicking was very rapid, I’ve never seen a Leafhopper doing this before.

Similar to the Leafhoppers are the aptly named Froghoppers (Cercopoidea). I’m pretty sure this is one of them or at least a related family, based on its very toad-like appearance.

Other common Insect visitors to my backyard are Lepidoptera (Butterflies and Moths). Skipper Butterflies (Family Hesperiidae) are some of the most common Butterflies around in my experience. They’re skittish and difficult to get close to because they’re seemingly always on the move, but I’ve had some good luck with a few in the past. Last month I was able to catch this Peck’s Skipper (Polites peckius) in a moment of rest with my Macro lens.

A much stranger Lepidopteran visitor was this bizarre Moth. Its wings look like a rolled up carpet, and its antennae look like tassels of said carpet. I’ve seen this same individual or at least a similar one in several different places around my yard, but always in this head down, wings up position. These Moths are classified as Crambidae (a Family) or Crambinae (a Subfamily) depending on the scheme being followed. There are thousands of species of Snout Moths (which is what these Moths are called), and I’m not sure where to begin on identifying my backyard variety.

We have a patch of Milkweed growing in our backyard, and I check it on a regular basis for signs of Monarch Butterfly activity. (there should be adults flying up North here during June and beginning to lay eggs). I still haven’t spotted any eggs or caterpillars on the Milkweed plants (when I wrote these observations in June, wait for the July Observations…), but several other creatures have been evident among them. One morning, at the top of each Milkweed plant there were young earwigs. I guess they were just resting there?

One creature that I have nowhere to begin with is this strange object… I feel like I’ve seen it before and found an ID for it, but I can’t recall what the ID was. I believe it’s some sort of insect (maybe a pupa?), but I don’t know:

Wandering about on the Milkweed leaves were what I like to call “Reverse Lady Beetles” because the typical Ladybug in my head is one that’s orange/red with black spots, where these Beetles were the opposite. I didn’t get great pictures of them yet (they’re smaller than the more common introduced Asian Lady Beetles (Harmonia axyridis)), but you can see what I mean.

I’m pretty sure these Lady Beetles are in the Genus Brachyacantha. At least one of the species in the Genus feeds on Hemiptera (mealybugs/aphids) in ant nests during its larval stage (presumably species that the ants are protecting for their honeydew secretions!) (Marshall, 2018).

A long-jawed Orbweaver (Tetragnatha) took up residence among the Milkweed as well, with a web that spanned between the leaves.

One final visitor of note was this Banded Longhorn Beetle (Typocerus velutinis). These Beetles develop as larvae inside decaying trees or logs, emerging as the beautiful Beetle seen here hanging beneath a leaf.
