I'm participating in Art Fight this year (for the 7th time in a row!) I'll be pretty busy this month but I'm hoping to do quite a few attacks :D If you have insect/arthropod characters and are participating, DM me with a link to your profile! Link: http://artfight.net/~arthro

Today I bring you a little hover fly, Toxomerus politus from the Syrphidae family. They mimic bees and are important pollinators. Registered in Rio Grande do Sul, Brasil.

I see at least one cool bug a day, and usually many more, but it’s not because I live anywhere particularly rich in strange, wonderful creatures (I live in an unremarkable corner of Pennsylvania, USA) or spend all of my free time looking for bugs (well, just *most* of it). in my experience, finding interesting bugs is less about actually locating them and more about looking closely at tiny things you’d otherwise ignore!

this very long post was compiled over a couple days in late July, although I spent less than 10 minutes at a time searching. there’s a lot of fun creatures just out in the open.

plants are always a good place to start when looking for bugs, and I chose this small fig tree (Ficus carica) with a mulberry sapling friend. feeding on the sap of the fig and mulberry is the first group I’ll take a look at, the planthoppers:

these two are flatid bugs, Metcalfa pruinosa and Flatormenis proxima. flatids are slow-moving bugs that can be approached closely, but once they get tired of circling around stems to avoid you they may launch themselves into a fluttering flight with spring-loaded rear legs.

Aplos simplex, a member of the related family Issidae, also likes fig sap. its “tail” is actually a tuft of waxy secretions, which get shed along with the bright colors when it assumes a lumpy, bean-shaped adult form.

cicadellids, or leafhoppers, are just about everywhere on plants, but can be hard to approach without scaring them.

Agallia constricta on the left is a tiny species that feeds on grass, but many were scared up onto the fig by my footsteps. Jikradia olitoria is a much larger species that does feed on the fig; juveniles like this are curled, creeping goblins while adults’ rounded wings give them a pill-shaped appearance.

this big, pale leafhopper belongs to genus Gyponana. it’s tricky to get to species ID with these.

Graphocephala are striking little hoppers that eat a variety of native and nonnative plants. G. coccinea is the larger, more boldly colored one and G. versuta is smaller but more common locally. they’ll sit on the tops of leaves but take flight if you get too close quickly.

another group you’re almost guaranteed to encounter are flies (Diptera). these are a very diverse group, so much more than houseflies and mosquitoes (though I did run into both)

where I live, any plant with broad leaves is almost guaranteed to have a few Condylostylus, long-legged flies that come in shades of blue, green, and red. despite their dainty physique, they’re agile predators, typically feeding on other small flies.

next, a few hoverflies: the ubiquitous Toxomerus geminatus and a Eumerus that I’ve been seeing a lot of this year (but maybe I’ve just noticed them for the first time). syrphids have varied life histories, but most adults drink nectar and many of the larvae are predaceous on aphids.

the metallic green soldier fly is Microchrysa flaviventris, nonnative here. Coenosia is a fun example of a “fly that looks like a fly,” with big red eyes and a gray body, and you might think they’re just another dung-sucking pest, but they’re actually aggressive predators! this one seemed to have nabbed itself some sort of nematoceran fly, maybe a fungus gnat.

many flies are very tiny, just millimeters long. the first two little fellows are lauxaniids, while the last one, an agromyzid leafminer Cerodontha dorsalis, burrows through grass leaves as a larva.

while moths and butterflies (Lepidoptera) are drawn to plants for their flowers or to lay eggs, many small moths can easily be found resting on or under leaves during the day.

these first two are tortricids, many of which are flat, rectangular moths resembling chips of bark or dead leaves. the apple bud moth, Platynota idaeusalis, feeds on a wide variety of hosts, while this beat-up old Argyrotaenia pinatubana would have developed in an edible tube nest of pine needles.

Callima argenticinctella feeds in bark and dead wood (a resource used by more caterpillars than you’d realize!) while the last moth, possibly an Aspilanta, is a leafminer.

although beetles (Coleoptera) are famous for their diversity, I didn’t find too many on the fig. the invasive Oriental beetle Exomala orientalis resting here can be found in a wide range of colors, from this common tan to to deep iridescent black. the other beetle is a Photinus pyralis firefly, sleeping under leaves as fireflies do.

a few spare hemipterans: a Kleidocerys resedae that blew in on a wind, and below, the mulberry whitefly Tetraleurodes mori feeds on its namesake host. as for Hymenoptera, I saw manny tiny parasitic braconid wasps and various ants attracted to the planthoppers’ honeydew excretions—always worth checking underneath roosting hoppers for things having a drink.

a couple handsome spider boys were scrambling through the fig seeking females, a jumping spider Paraphidippus aurantius and an orbweaver, Mecynogea lemniscata.

and to round it off, a young Conocephalus meadow katydid and a Carolina mantis, Stagmomantis carolina.

there’s 31 species of arthropod in this post, and I probably saw some 45, not all of which stayed for photos. if you walk slowly and look closely, you can see a sizeable chunk of your local biodiversity in under fifteen minutes! of course this will depend on where you live and what time of year it is, but there’s almost always more cool bugs out there than you’d expect, even on just a single plant.

Syrphid Fly (Toxomerus geminatus)

How splendid to begin the day by bathing in a dew drop.

@alhexy submitted: a tiny guy and some beetle guy

im pretty sure the hover fly / bee mimic is from the genus toxomerus and ive also seen a decent variety of bumblebees, im not sure of the species of the bee in the picture and was wondering if you thought it could be a Rusty Patch bumblebee? im not good with bumblebee ID (in Maine) (if you cant ID, dont worry)

i think this is a robberfly? and a really cool spider

a nice water strider :)

i believe the small blue/black/gray guys on the water surface are marine spring tails

Great bunch of pals! If they were found on the coast in Maine then the springtails could be marine springtails, but if they were on freshwater then they were likely just water springtails. The bumblebee looks like a tricolored bumblebee, Bombus ternarius. And yes the dude after that is a robber fly!

Summer is Bursting with Bugs! (Species in order of presentation, my best guesses!)

Neokolla hieroglyphica Mecaphesa asperata Synema parvulum Bombus bimaculatus Toxomerus marginatus Mining Bee (Species uncertain!)

Though I don't get to see many reptiles and amphibians in Iowa, I at least get to see lots of bugs. Those that fly are particularly difficult to keep still while taking a quick photo, so I've been practicing taking clear shots on small subjects like them. In other news, I did go ahead and order a 200-800m lens, but it's been months and It seems I'm in the same boat as many others, waiting for that email of shipment. Once I get that though, it's literally a whole new world of possibility for me in terms of what kind of wildlife I can try and photograph!

Calligrapher flies / genus Toxomerus

Calligrapher Fly, likely Eastern Calligrapher (Toxomerus geminatus) on some Mint...

#1 hobby these days is just going on an evening walk through the neighborhood and using Seek to id any flowers or bugs i see :3

Common Soapwort Saponaria officinalis is nonnative but can be used to make soap!! Wild Four O’Clock Mirabilis nyctaginea is native and a host to at least four species of micromoths’ caterpillars.

Butterfly Milkweed Asclepias tuberosa is native and attracts butterflies and other pollinators including this common eastern bumble bee Bombus impatiens ! and this last guy is the Eastern Calligrapher Toxomerus geminatus, which is a native species of flower fly. they exhibit batesian mimicry with the yellow and black stripes but are harmless to humans; their larvae prey on pests like aphids.

Toxomerus marginatus

Margined calligrapher

24 of June 2022 — Maryland, USA

Interesting fact: the larvae of these flies predate on thrips, aphids, and caterpillars. Adults are pollinators.
