There's a new episode of the Arthro-Pod podcast out. We interviewed @toomanywasps.bsky.social about gall wasps, especially the understudied herb gall wasps.

Vampire moths might sound more horror film than natural world, but they’re 100% real! 😱

See why some moths pick human blood over fruit juice in this week’s Surprising Science. 🩸🦇

Does #SexualSelection fuel #Speciation?

Our new #meta-analysis of comparative studies finds support for a positive relationship, but the rather moderate global effect suggests it’s not necessarily a dominant force.

More wasps from Sichuan! This time we describe a new rose gall found on a protected endemic rose from China. We named the gall wasp Diplolepis nezha and its ichneumonid parasitoid Orthopelma aobing, after characters from the Chinese legend/popular animated film.

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
Two photographs of black wasps that look roughly the same except that top one has hairy antennae with large gaps in between the segments, while the bottom one has more beadlike antennae. The lower one also has an ovipositor. Their legs are partly orange and their head and thorax have pits and short white hairs.

Dark taxa are extremely diverse organisms that remain largely undescribed due to small size, subtle differences, & few experts.
