Just got a pdf of this entire work on #chalcidoidea for a fraction of what I paid for the hard copy! Take a look: biologylibrary.online

Unforgettable #Hymathon2025, a virtual symposium of International Society of Hymenopterists Hymathon is the society’s annual 24-hour-long marathon of Hymenoptera! Join online from anywhere in the world to listen to presentations from Hymenopterists, present your own research, participate in social events and make new connections. It is full of research talks, fun events, and more than a small amount of chaos as the 24 hours reaches the end! Hymathon 2025 occurred on 4–5 December 2025, with four sessions over the 24 hour period.
Unforgettable #Hymathon2025 ❤️
Looking forward to our new meetings with @hymenopterists.bsky.social

If you have thoughts on identification I'm always grateful for help. Here's the male. #wasps #chalcidoidea #inaturalist www.inaturalist.org/observations...

Most likely an imaginary species of Metapelma. Drawn in coloured pencils and white posca marker.
This wasp is a Metapelma sp. , or perhaps even an imaginary species of Metapelma. Coloured pencils and white posca marker on 8½ x 11 cardstock. I tried my best.

Metapelma sp. viewed from underneath.
My best attempt at drawing a species of Metapelma sp. viewed from underneath. It's crazy how hairy they are in real life. A very rainbowy species when viewed up close. Perhaps my pencils are a little too saturated? 🤔

Detaillierte Makroaufnahme einer Monodontomerus obsoletus-Wespe, die die charakteristische metallisch grün-bronzene Färbung von Kopf und Thorax zeigt. Das Bild erfasst die markanten roten Facettenaugen, die segmentierten Antennen und die typische skulpturierte Oberflächenstruktur des Exoskeletts. Die Wespe ist vor einem unscharfen Holzuntergrund positioniert.
Seitenansicht einer Monodontomerus obsoletus-Wespe, die ihre vollständige Körperstruktur mit metallisch grün-bronzenem Thorax, klaren häutigen Flügeln und charakteristischen roten Augen zeigt. Die Aufnahme verdeutlicht den robusten Körperbau und die detaillierte Flügeladerung. Das Exemplar wurde auf einer Holzoberfläche mit geringer Schärfentiefe fotografiert.
Dorsale Ansicht einer Monodontomerus obsoletus-Wespe, die den irisierenden metallischen Glanz der Körperoberfläche und die gefalteten transparenten Flügel hervorhebt. Das Bild zeigt deutlich die segmentierten Antennen, roten Facettenaugen und die charakteristischen Körperproportionen dieser Erzwespenart. Das Exemplar ruht auf verwittertem Holz.
An Nisthilfen kann man die ca. 4 mm große #Erzwespe (Monodontomerus aeneus) beobachten. Sie legt ihre Eier in den Nestern von Mauerbienen (Osmia spec.) ab. Die Larven ernähren sich von der Wildbienenbrut.

Graphical abstract of: Phasing in and out of phytophagy - phylogeny and evolution of the family Eurytomidae (Hymenoptera: Chalcidoidea) based on Ultraconserved Elements
A new #RESSystematicEnt article presents the phylogeny & evolution of the family #Eurytomidae #(Hymenoptera: #Chalcidoidea) based on #UltraconservedElements
Secondary phytophagy evolved independently at least 7 times🔽

A close-up photograph of a bright green serrated leaf, photographed in natural light. Near the edge of the leaf, two very small dark insects—members of the Chalcidoidea superfamily—are visible in mid-interaction. The insects are black and shiny, with delicate wings, and they appear to be chasing or responding to each other. The leaf is covered in tiny white hairs and has pinkish tips on its serrations. The background is softly blurred in green tones, suggesting surrounding vegetation and providing a natural contrast to the sharp detail of the foreground.
An extreme macro crop of the previous image, focusing tightly on the two Chalcidoidea. The insects are now more visible in detail: one slightly blurred in the foreground with iridescent wings, and the other sharply focused as it stands on the leaf edge. The fine textures of the leaf surface are clear, including its tiny hairs and pink-tipped serrations. The lighting highlights the reflective quality of the insects’ bodies and wings, emphasizing their small size and intricate anatomy against the vibrant green background.
This was a bit of a focus fail, but I didn’t have time to switch to my 5:1. Two Chalcidoidea started chasing each other along the leaf edge. These were tiny! Below even my usual 2mm size.

Side view of the wasp with both wings and eyes visible. The metallic shine on its thorax and abdomen is especially vivid here. Its legs cling to the leaf surface, and fine details of the leaf texture are visible.
Frontal macro shot of the wasp standing on the edge of a leaf. Its head is in sharp focus, with both red eyes visible and antennae lifted upright. The background fades into a blur of dark green and black.

Close-up view of the chalcid wasp's head and upper body from the side. The wasp is on a bright green leaf, showing off its shimmering exoskeleton and red eyes. Its antennae are prominently detailed, with a soft bokeh background in dark tones
A very cooperative chalcid wasp, smaller than a grain of rice (~3mm), yet dazzling. When people ask “Why bugs?”, I show them insects like this. Metallic, red-eyed, and basically a real-life xenomorph in biology.

Lateral habitus of a point-mounted rose seed chalcid, Megastigmus nigrovariegatus. She is about 4 mm long and a mottled golden brown color.
The Rosa acicularis seed from which the wasp emerged. A tiny circular hole is visible on the surface, which the wasp chewed when she was ready to emerge from the seed.
Seed-feeding chalcids are always a favorite to rear out; getting a whole adult wasp out of a tiny seed is nearly magical! This tiny rose seed chalcid (Megastigmus nigrovariegatus) emerged this week from a wild rose seed (Rosa acicularis) collected last month. 😍 🧪 #chalcidoidea #entomology #Alaska

Side view of a metallic green to orange wasp with a black appendage at the end, the same length as the rest of her body. These are the sheaths in which the ovipositor usually rests. She currently uses it to deposit her eggs into green fruit on which she sits. The background is blurry dark green from trees and blue sky.
This beautiful metallic #chalcidoidea wasp Torymus varians is drilling her super long ovipositor into a hawthorn berry
(protective sheaths stay in place)
It's one of the species, which are actually phytophagous and her larvae will feed on seeds inside

Fabulous Astichus arithmeticus 🤩
One of my favorite chalcidoid wasps.
Using her ovipositor she's probing a bracket fungus for beetle larvae within and lays eggs into them so her larvae can feed on them 1/2

The #Eurytomidae UCE phylogeny that I've been working on in the past few years is now out as a preprint. By using museum samples at NMNH and CIRAD, we generated the first global phylogeny of this diverse but poorly studied #Chalcidoidea family. 🧪

Side view of a shiny, metallic green wasp with bright red eyes and an ovipositor longer than her body. She cleans the diagonal ovipositor with her back legs.
3mm wasp, possible Genus Torymus, cleaning her ovipositor. Photographed summer of 2024 in the Proctor section of the Great Smoky Mountains National Park, found in an overgrown wet field.
