How is this possible? This ant can lay eggs of two different species, birthed by the same mother

Excited to share our Dispatch discussing how Trichogramma egg parasitoid wasps effectively use oviposition-induced plant volatiles in long-distance host location and quality assessment Agroecology: It’s about time for oviposition-induced cue use: Current Biology www.cell.com/current-biol...

A nice collection of papers on herbivore detection in plants including our paper on the evolution of butterfly egg-killing in this virtual issue! @lottecaarls.bsky.social

A word to the wise: we have only 27 slots left out of 200 in this GRC and Jan. 19 is the deadline to register. If you want to go, apply now and then you can register. Many steps. Despite the terrible fires in LA (my heart goes out to all of you in LA), we expect the conference to be held as planned.

Butterfly fact 6. Eggs, larvae and pupae are eaten by a host of predators. But their biggest killers are parasitoids that can kill 90%+. This astonishing photo by @trichogramma74.bsky.social shows a Trichogramma on Large White eggs. It hitches a lift on ♀♀. Details in Butterflies from Bloomsbury.

Good news! Our study by Bassetti et al. on R-genes involved in butterfly egg-killing cell death in Brassica has received over 1,000 views since publication! Read it here onlinelibrary.wiley.com/doi/10.1111/pc…#ViewsMilestonene

Thanks to my students during the first-years Fauna course I could witness this giant #ichneumonid wasp Megarhyssa rixator in action, parasitizing the larva of a giant woodwasp inside the wood with her mega long and flexible ovipositor. #biodiversity of NL @w-u-r.bsky.social
