To end the week, a cynipoid with crazy long antennae I found in the MNHN collection this morning! 👀✨ #wasp #insect

Male and female chalcids that emerged from redbud seedpods. Both are in the genus Eurytoma and are possibly the same species but further identification is beyond my skill set. I can't find any mention of them being recorded as parasitoids of redbud bruchids. 🌿 #wasps #hymenoptera #insects #bruchidae

Not my photograph but thought others would enjoy. And if you know what it is, Kenneth Geisert would appreciate an ID. 🌿 #lepidoptera #peru #insects #moths #inaturalist www.inaturalist.org/observations...

Dark taxa are extremely diverse organisms that remain largely undescribed due to small size, subtle differences, & few experts. Take this quiz to find out what you are - I'm a gall midge! whatdarktaxonareyou.static.domains/insect-quiz.... by @vivianfeng.bsky.social & @flyliceresearch.bsky.social

New Harvard grant terminations in the geosciences (plus others - geosciences are just my jam) are up at grant-watch.us/nsf-data.html. They include work on tracking mercury pollution in the Arctic; the longterm atmospheric impacts of 2022's Tongan eruption; and how earthquakes rupture the ground. ☠️

Spring 2025 has been very good for the Map (A levana, landkaartje) on Dutch Butterfly Monitoring transects, recovering after a series of dry years with a large 3rd gen in 2024. However the lack of rain now is also worrying for the next generations.

The Dutch Grassland Butterfly indicator (www.clo.nl/indicatoren/...) shows a decline of more than 70%. It will be hard to achieve an increasing trend in 2030, as required in art 11 in the Nature Restoration Regulation (eur-lex.europa.eu/legal-conten...).

New #gall #wasp paper from our lab! We review the genera of Phanacidini herb gall wasps, present the first record from China, and identify a new tribal diagnostic character! Now onto revising the species and genera… every synonymized genus needs to be resurrected! www.mapress.com/zt/article/v...

So some extraordinary news came out today! We have received footage for the first time of a colossal squid in it's natural habitat! I remember watching the footage live and being in chat saying "Could this be Mesonychoteuthis hamiltoni"? And glad to hear it was!! www.youtube.com/watch?v=lzPo...

Cuts to #science of >50% at NASA and >75% at NOAA would end US climate and space science research. NASA cuts are '...an "extinction level" event': arstechnica.com/space/2025/0... "At this funding level, Office of Oceanic and Atmospheric Research is eliminated...": www.science.org/content/arti...

BREAKING from @science.org: The Trump admin is seeking to kill nearly all climate research at NOAA, its climate science agency. Its near-final budget proposal would end all NOAA research labs, academic institutes, and regional climate centers. And it wants to fully end the NOAA Research division.

So many Ichneumonids, so little time. I collected this Exetastes bifenestratus, a species I'd never seen before, at a blacklight in central Texas.

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. 🪲🪳 #Invertebrate #macrophotography #Chalcidoidea 🌿 #entomology #hymenoptera

Nugget 🖤 I love when encyrtids have white-tipped antennae, so when they're flapping them as they run it makes them so much easier to spot 🥹

A silly Mope* on the hunt for whatever her tiny quarry is (I've seen this species of Eupelmid wasp ovipositing into the head of a pine needle cluster). I think the last one I saw was when @jencross.bsky.social visited last year.
