The discovery of a new “species” invariably leads to the discovery of new “species interactions” - new connections in the web of life. Here, the discovery of a new gall wasp also uncovered EIGHT new interactions with other insects - some likely new species as well. #biodiversity @ymilesz.bsky.social

#NewSpeciesAlert! We discovered & described a new species of gall wasp, Belonocnema mesoamericana, on the central American live oak, Quercus oleoides. Great collaboration between Alejandro Zaldivar & lab at #UNAM, @ymilesz.bsky.social at #EdinburghUni, and my lab at #RiceUniversity. #biodiversity

So fun to collaborate with you @ymilesz.bsky.social! And as we both know, this is just the tip of the “biodiversity iceberg” in the live oak-gall wasp system.

Meet Belonocnema mesoamericana, a new species of Belonocnema that we described on Mexican live oak! This is a fun little critter that makes velvety root galls, a great find by @scottpegan.bsky.social and Alejandro Zaldívar-Riverón's team at UNAM.
