Submitter comment: "this is a personal favorite of mine. the moby dick reference is well-deserved for the task of reworking what was essentially a burning dumpster fire of a taxon"

Pretty, but painful! I really appreciate all the kind comments I've gotten on my recent works lately. I've been really driven to create and challenge myself. Today's model is the Pacific Velvet Ant, or Dasymutilla aureola. For some reason my scanner doesn't pick up hair details very well. The first picture is the scan, the second is a picture taken with my phone. This subject was really fun to draw! I may draw some cool Chalcidoid wasp next! Taking a small break for now.

lao papaya salads sometimes have unripe figs in them. it adds a nice crunch to the salad and mellows out the fermented papaya

it also gives you an opportunity to meet new chalcidoid wasps with ridiculous ovipositor:body ratios

a fun wasp for your appreciation: this is Leucospis affinis. like some other chalcidoids, she’s got thick “thighs,” although she’s a giant compared to the tiny parasitoids she’s related to, at about the size of a yellowjacket wasp (a little smaller, really).

Leucospis has a very long ovipositor that rests curved over her back. when she finds a suitable piece of wood that has a leafcutter bee nest in it, she seemingly splits her abdomen in half, unsheathing the wire-like inner portion of the ovipositor that she uses to drill through the wood to reach her target.

a cute face!

unusually for chalcidoids, her wings are furled when at rest and stick out at angles, rather than lying flat on her back. this, plus her large size and black-yellow-maroon color scheme, makes her an almost perfect mimic of local potter wasps—a good thing to be disguised as, since while she cannot sting with her ovipositor, potter wasps definitely can.

her mimicry was so good that I thought I was looking at two Euodynerus hidalgo boreoorientalis nectaring on this boneset. the second one is the real thing, though—no crazy ovipositor or beefy thighs!

Some little guys I saw while I was hanging around near the pollinator plants at the Arizona Sonoran Desert Museum today:

Chalcidoid wasp / superfamily Chalcidoidae

Honey bee / genus Apis

Paper wasp / genus Polistes

[sandpaperoctopi]

Some of the wasps I saw in 2022 in no particular order (other than the first, all were in my backyard!)

Diplolepis polita, Closterocerus sp., Chlorion aerarium, fairy wasp of some kind

Anomalon sp., chalcidoid wasp, another chalcidoid wasp, flat wasp

Vespula pensylvanica, Pepsis sp., ichneumonid wasp, Sceliphron caementarium

another chalcidoid wasp, braconid wasps, Stigmus sp., Anastatus sp.

open to corrections on any IDs of course :)

Chalcidoid wasp, Leucospis dorsigera, Leucospidae

Found throughout Europe, this species is a parasitoid of certain wasps and bees. Photos 1-4 show a female ovipositing her eggs into wood that contains larvae of a host species.

My favorite photos of 2023, for @luxlit's Year End Top 5 Photo Extravaganza that will run for 24 hours on New Year's Day. It's a great place to check out the photography talent here on tumblr, and maybe find some new blogs to follow.

You can also find me at my main blog @celestialphotography (scenics and travel) and my bird blog @occasionallybirds

Tan Jumping Spider (Platycryptus undatus)

Longhorn Bee, Melissodes sp.

Euperilampus triangularis, a member of Chalcidoid Wasps

Possibly Alfalfa Leafcutter Bee (Megachile rotundata)

Some sort of Nut and Acorn Weevil (Curculio sp.)

hiii im showing up to this post years later but wanted to say that the first and third wasps here are actually cynipoids!! you can tell this because their wing veins have closed cells - chalcidoids never have closed cells in their wings :-)

so gall wasps, or inquilines of galls and such! all very cool and tiny guys an easy mistake to make

Tiny parasitoid wasps (: though they are very difficult to ID I think they are very fascinating

the hymenopteran family Pteromalidae is a hyper-diverse (probably polyphyletic) group of parasitoid wasps. there's currently thousands of described species but with how understudied parasitoid wasps are, there's probably actually a shitload more than that. anyway most species are somewhere around 1-3mm long, often barely discernible without a microscope. but i read somewhere that they range up to almost 50mm, about 2 inches, which is huge for any insect and positively gargantuan for a pteromalid. so of course i had to go and look up what the biggest one was. turns out it's Doddifoenus wallacei and while a big chunk of that 50 mm length is ovipositor, it's still way less than i expected!

here's some other impressive species in the same genus:
