*black eggs --> Anoecia zirnitsi, host: Lasius flavus
*eggs rapidly retrieved among ant brood and protected against predators and fungi
*mediated by chemical cues, transferred to glass dummies

A histerid beetle during takeoff. We found this specimen in an army ant refuse deposit in Costa Rica, but we never figured out what species it is.

The blind white isopod Platyarthrus hoffmannseggii thrives in #ant nests, abundant in temperate Europe and introduced in USA.
Much more to discover about this #myrmecophile ...

Some years ago, we reported surprisingly differences in body size across host species doi.org/10.1093/biol...

#waspday at @NHM London!! look this amazing Polybia nest!!! thanks @gavinbroad.bsky.social with @waspwoman.bsky.social @femi-benny.bsky.social @ionace.bsky.social

As a first post, we can now announce that we have started our already successful Citizen Science project on INaturalist.

Once joined, every observation can be assigned to this project (even retrospectively). So please share this and map out some ant mounds. 🐜🌳
