infographic for an insect macrophotography workshop featuring photo of a wasp
Interested in insect macrophotography? If you are in the midwest, think about attending this workshop put on by @ageofarthropods.bsky.social and myself, 2-3 May 2026 cvent.me/qK5bOo
Black and yellow wasp on a green leaf is running its mouthparts over the leaf’s surface to scoop up a sticky coating of aphid excrement
A wasp from the front as it walks across a leaf dragging its mouthparts along the surface
An aphid coated in white was sitting on a maple leaf.
I was late to a meeting last week watching these yellowjackets lick honeydew off of an aphid-infested maple tree.
Thinking about buying a macro lens for insect photography? Along with @ageofarthropods.bsky.social we have been testing many options! Our results are summarized in 2 blog posts in the field www.insectid.org/post/macro-l... and in the lab www.insectid.org/post/lab-tes...
A small reddish brown beetle is walking on a white sheet where it was attracted to a blacklight. It has a mite on its head which must have hitched a ride from its nearby home either under some leaf litter or in a dead log.
This little brown beetle wearing a mite hat is Cryptophilus angustus - a pleasing fungus beetle that is often confused for several other families of tiny beetles
This hackberry (Celtis occidentalis) came in today with galls. The immature psyllids inside don't even look real!
Ever seen a mantis drink water from a paintbrush? Might have been the most fun I've had with a live insect that wasn't a beetle. Thanks to @ageofarthropods.bsky.social for the idea and help!
Yup, down on the flats towards Rodeo
A large, seemingly inflated black beetle with orange red markings on it. The abdomen is blown up and it has tiny hardened front wings which don’t cover its body.
A smaller individual of the same species which seems to have had the abdomen shrivel up some.
The large individual curled into the fetal position with an orange glob of its toxic blood secreted around its head to avoid predation and hopefully deter entomologists. Unfortunately for him, I had forceps.
Two specimens of Megetra punctata from southeastern Arizona. Surprisingly the smaller one was a female and the larger a male - I think size is totally related to how much blustery ooze they have left in them and not correlated to gender. These things reflex bleed as soon as they are touched!
Large black beetle stands with its strong mandibles open, daring you to get your finger too close.
Cottonwood stag beetle, Lucanus mazama from southeastern Arizona. This male stayed still for images which was very kind
A dull orange-red beetle with short wing covered that are suffused with black tips is standing on a white sheet. The beetle has four long black tentacle-like projections from its mouth. This identifies it as a male.
I’m always excited to find a long-lipped beetle (Telegeusis sp). This one is from Hank Canyon in southern Arizona
The body is not quite 2 inches long. A good sized beetle!
An orange and black banded beetle on a white background with extremely long antennae
A lateral shot of the same orange and black banded beetle.
The long-jawed longhorn beetle, Dendrobias mandibularis, from southern Arizona. One of very many cool beetles we are finding at this years Beetle Course!
Transparent cascading funnels lead to a collecting jar with a blacklight hung through the middle. The whole funnel assembly hangs on a tripod in a sandy plain
A New Mexico sunset is on the horizon behind the trap assembly
A second funnel trap is hung from a dead stalk of bear grass with heavily vegetated sand hummocks in the background
A jar full of the insect bounty from just under an hour of running the traps.
Tried out my new blacklight funnels I built. Got chased off the eastern New Mexico plains by a nasty thunderstorm, but less than an hour produced quite a few beetles!
If only Horn had remembered recording it from New York and South Carolina in his 1870 revision of the family.
Want to set up your own photo-stacking imaging system for under $3000? This post which outlines all the off-the-shelf items I used this year along with some recommendations for how to use it. Planning to talk about this at @entcollnet.bsky.social this November, too! www.insectid.org/post/focus-s...
An insect that looks like a sausage with a head that is almost completely eyes with fly wings. But it's a beetle.
Atractocerus brasiliensis - what a weirdo.
A reddish brown beetle hides in its circular gallery inside a tree branch cut in half. The beetle looks like it was sawn off along with the wood when it was split.
A side view of the reddish brown beetle inside of its gallery. The gallery walls have some white ambrosia fungus growing inside which the beetles brought with them. The beetle fit snuggly in the gallery and could not be easily removed by another insect its size.
The beetle is crawling out on the wood. The proportions are off for a normal beetle with the head and prothorax being about equal to the rest of the body.
A more hardened individual with black cuticle walks along the split stick looking for a crevice to get into and hide from the camera lens.
I hacked into a trunk of a Japanese Cherry tree sent for diagnosis of borer damage. These silly Camphor Shot Borers were inside (Cnestus mutilatus). They look like their backside was chopped off - but if you find them in their galleries you find out how effective they are at keeping them safe!
A white fluffy mass of wax that looks a bit like a colonial wig crawls along the underside of a green tuliptree leaf. Between the cottony wisps you can see hints of the pinkish red cuticle of this insect larva.
The same larva is now crawling up the narrow leaf petiole. This picture shows its underside which is pinkish with dark legs.
The insect is seen again on the leaf surface from the side
A pinkish almost alien looking insect host is shown under a microscope after being preserved in alcohol. Its head is visible here showing a black modeled shape with short antennae and mandibles.
I received a sample of Tuliptree yesterday with a concern for mealy bugs or aphids. What they had seen were these lady beetle larvae (Hyperaspis sp) which I always have to flip over to be sure about. They had been grazing on a massive scale infestation which had caused a thick sooty mold outbreak.
Probably the genus Canifa, but definitely Scraptiinae. They can drop that terminal segment just like some lizards drop their tails in order to distract a predator. Super cool!
An adult streaked river birch aphid sits on the underside of a green leaf. The aphid is pale yellow-green with black stripes down its head and thorax and has skinny black legs and dark black wing veins on otherwise transparent wings.
The underside of this wrinkled birch leaf has a crevice full of wax and flat oval insects. Most of them are reddish immature aphids which are joined by two darker colored adults, one with wings. They are covered with patches of white wax which they excrete for their own protection.
A deformed and puckered leaf of a river birch shows signs of sooty mold and discoloration of dead leaf tissue. The gnarled ridges (pseudogalls) are formed by an aphid pest.
The underside of the same birch leaf is shown where a few waxy aphids can barely be seen inside the folds caused by the deformed leaf growth that their feeding has caused
I learned two new aphids this week, both from black/river birch. The streaked river birch aphid was quite handsome while the waxy Spiny Witchhazel Gall Aphid has a super cool biology with alternating hosts (witchhazel and birch) and makes those puckered creases in the leaves of birch
A black potter wasp with yellow markings uses its mandibles to rip holes out of a leaf. An out of focus white blob can be seen inside one of the holes, foretelling why the wasp is doing this work.
The wasp works its way over the leaf, feeling with its antennae into one of the holes it cut into the leaf.
The wasp has pulled its head back from the leaf and has a white caterpillar in its jaws.
The wasp has a tight grip on its caterpillar prey and has crawled to the end of the leaf from where it is about to take off and provision its young with this parasitized meal.
Today I watched this potter wasp cut apart a leaf (Paranocistrocerus perennis?). I was trying to figure out what it would do with the leaf before I realized it was pulling out the caterpillar inside that had tied it shut!
Two brown weevils sitting on top of a carrot in front of a green background. A male weevil clings tightly to a female hoping to pass his genes on to the next generation.
A weevil plays dead laying on its back with its legs and antennae fixed rigidly against its body. Super convincing.
Carrot weevils (Listronotus oregonensis) are as derpy as most of their relatives. I like their death feigning pose that is in perfect bilateral symmetry.
Any luck getting general stored grain/product beetles from moldy hay sifting? I'm looking to start some colonies in the lab. Did you use a litter sifter and berlese/winkler? (also, cool beetle)
Two reddish orange mites are facing each other and either sharing or fighting over a dead aphid. The entire scene takes place on a green leaf showing some feeding damage either by aphids or other mites.
These mites (Phytoseiidae?) feeding on an aphid are sort of metal. Not sure if they were sharing or fighting over this resource.
A pitch black ambrosia beetle sits in her T-shaped gallery that she chewed through a Japanese Maple branch
A black beetle with reddish legs and antennae, about 4 mm long, is crawling along a split branch after being rudely interrupted in excavating a gallery to raise her young within.
The posterior end of a black beetle sticks out of a hole chewed into the crotch of a tree branch. The beetle is trying to get back in to her gallery to hide from any would-be predators.
The bumpy black thorax and top of the head of an ambrosia beetle closes off her gallery. Predators or other invaders to her gallery will have a tough time getting past her tightly wedged body which is plugging the hole to the rest of her gallery.
This is the European Shot-hole Borer (Anisandrus dispar) that came in a sample of Japanese Maple stems. This female hasn't laid eggs yet and can be really difficult to get out of her gallery if you don't split the stick correctly. Glad I took a Bark Beetle ID Workshop last week to figure this out!
A reddish oval insect is sitting on a white background with legs and antennae oustretched. The body is outlined with a fringe of long, stout hairs and the surface is covered in strong punctures. The tail end of the abdomen has a dark blotch within which is the remnants of a former blood meal for this bat bug found inside an Indiana home.
A reddish brown bug is looking towards the camera with its legs and antennae outstretched. The body texture is dotted with deep punctures.
Some days I get to play the "is it a bed bug" game as an insect diagnostician. Today, our client was fortunate enough to submit an Eastern Bat Bug - Cimex adjunctus. The fringe of long hairs on its prothorax (just behind the head) which are longer than the eye separates this from the common Bed Bug.
A creamy-yellowish and almost translucent beetle larva is sitting on a dead log where the bark has just been removed. The head bears hardened reddish mandibles, digesting wood and fungi are visible in the gut and appear as a long black tube through most of the insect's body. The hind end of the larva is hardened into a reddish plate with two long cickle-shaped points.
Its almost impossible not to find these fire-colored beetle larvae under bark of a nice rotting log. But the adults never seem abundant to me. This is probably Dendroides canadensis and has a few more molts to go before pupating.
A spider with a red body, pale legs, and hairy black pedipalps sitting under some silken strands on a green leaf
Found this spider for #invertefest in northeastern Oklahoma. I should really learn spider IDs some day!
Head of a dark black beetle from the side, with a dense tuft of golden hair just underneath its chin
Underside of the head of a black beetle showing a dense tuft of golden setae on its lower lip (called the mentum).
The golden goatee of this darkling beetle always makes me chuckle. What's it for?? Alobates barbatus and its fancy facial hair can be found throughout the eastern United States and co-occurs with Alobates pensylvanicus that looks almost identical, except for lacking this tuft of setae.
