#NewSpecies!
Proud to announce the publication of my first two species descriptions! Working on this first author paper has been one of the most rewarding things I've ever done in my life, I feel beyond belief fortunate to be able to study these beautiful animals.

--species are parasitoids of beetle, bee, or wasp larvae. Others seek out spider egg sacs, or hop aboard female spiders with the intent to parasitize the egg sacs when the spiders construct them. Mantispid larvae then chew through the silk and live inside, eating spider eggs. #inverts #insects
A macro photo, side angle, of an insect called a mantidfly against a pure white background. The insect is facing left. It's overall a mix of dark and light brown/tan, with large, round, rainbow-green compound eyes. It's a long, thin insect, with mantis-like raptorial forelegs, clear lacewing-like wings folded along its back, and giraffe-neck-like extension of the thorax. Overall, it looks like a mashup of a mantis and a lacewing, hence the common name.

Best way I can think of putting it:
You know the start to Stand by Me? www.youtube.com/watch?v=einn...

🎶"When the night has come
And the land is dark
And the moon is the only light we'll see"🎶

That's kinda the vibes here. Pretty fitting, "moon mili" was always there, just waiting for us to find!❤️

Dang, A+ name! 🤩

Extra context (as they are underselling it):
A 霽月/Jìyuè moon, as in the idiom 光風霽月, has this great sense of tranquility & hope to it, a sign that the intense storm is finally gone & the night is calm again, where you let out that breath you didn't know you were holding in.

I HAVE to highlight the most poetic etymology section I've ever read for a millipede: "Jiyue (Chinese spelling) alludes to the bright white appearance when the animal emerges from the leaf mold, like the moon appearing from behind a dark rain cloud." Source: zookeys.pensoft.net/article/1280...

Not only did I get to see a gorgeous old friend roaming the familiar boardwalk again this afternoon, but I saw her ovipositing into something in the wood, for the first time!
Hope to see her next generation, next year 🖤
Uropelma formosum, eupelmid wasp. Mope. 🧪
Slender mopy wasp, with a green head, thin antennae, tan thorax with a purple stripe across the sides, tiny wing stubs, and a dark iridescent abdomen terminated by a black feathery ovipositor sheath(?). She's paused over a slight blemish in the wood, abdomen arched, thin ovipositor proper injected into the blemish.

Urodid moth cocoon, Costa Rica. The basket hangs by a thread (possibly to discourage ants) and the structure may allow rain to drain and/or prevent mold. But it doesn't stop parasites - I think the seed-like ovals are cocoons of parasitic flies or wasps, indicating the moth pupa's likely fate. 🐙🌿
A macro photo, vertical orientation, of an unusual moth cocoon, spun out of gold silk but in an oval-shaped, open-weave basket that looks like wire mesh. Part of a green leaf is out of focus in the background, and the top of the basket is attached to a white woven thread extending up out of frame. In the lower left half of the cocoon are a dozen or so small, gray, seed-like structures that are probably the cocoons of tiny parasitic wasps or flies, indicating they parasitized the moth pupa that originally made the mesh cocoon.

Graduate student @kylethieringer.com and I wrote a dispatch about a new @currentbiology.bsky.social paper (doi.org/10.1016/j.cu...) describing a proprioceptive neural circuit that helps the fly visual system identify (and ignore) its own legs.

I enjoy recognizing behaviors supposedly typical of bees in some of their ancestors, the wasps. A digger or thread-waisted wasp, Ammophila heydeni (Sphecidae), still sleeping shortly after dawn clinging to a twig with its mandibles, as commonly done by many solitary bees sporting strong mandibles.

Neat little wasp with muscular hind legs :)
Although I see Chalcidoidea almost daily, this was only my second Chalcididae. IV.2024

The sheer elegance of wasps! Here’s a Spathius that arrived to a blacklight sheet in west Texas.
Photo of a slender, elongate orange insect in side view standing in a pure white field. The insect has long threadlike antennae and a needlelike tail nearly the same length as its body.

Pheidole militicida desert big-headed ant sisters. Major workers (left) and minor workers are set on different developmental trajectories by environmental stimuli as larvae, and mature to perform different roles in the colony. Arizona.
Photo of two ants facing each other on a clean white background. The ant at left is orange and massive, with a head that's nearly as big as the rest of its body, and small black eyes set low on its face near its mandibles. The ant at right is smaller, black, shiny, and slender.

Our false head work is out! By analysing ~1000 #butterflies, we found many traits at posterior end of hindwings evolved correlatedly, likely forming a trait complex w/adaptive function to dupe predators into thinking these traits together are actual head!!

If you plant a mountain mint/Pycnanthemum in an area where they are native, you will get the weirdest bees and wasps you have ever seen, and they will ignore you.
