Finishing our database is a hugely ambitious task and we won't be able to do it alone. If you're interested in learning about galls, we would love to help you do that by having you join our team and build out part of our database. @ us or DM for details.

This bald cypress tree had more galls per branch than any tree I've ever seen. Galled by Cypress twig gall midge, Taxodiomyia cupressiananassa

Wow! 🤯 Just learned that our lab’s research is featured in a kid’s book about insects! ❤️ “In 2022, biologists identified a new type of gall wasp called Neuroterus valhalla. Spotted on the branches of a huge oak tree on the campus of @RiceUniversity.” – at Houston, TX

MicroCT scan of crypt galls induced by the cynipid wasp Bassettia pallida within branches of the southern live oak, Quercus virginiana. Hiding in the crypts are a second parasitoid wasp, the crypt-keeper - Euderus set! #biodiversity

Gall of the week is that of the curiously two-chambered one of the cynipid wasp Cynips disticha f. agamic on oaks, Quercus spp. Photos by Malcolm Storey.

Gall of the week: @britgalls is in Ohio USA, and came across this. Seems to be a rough oak bulletgall caused by the cynipid wasp Disholcaspis quercusmamma on swamp white oak, Quercus bicolor. Happy to be corrected. Photo by Peter Shirley.

In case you ever wondered how anyone discovered the idea of making ink from galls--Disholcaspis gall juice turns black on contact with metal in seconds

Gall of the week is the little gem caused by the cynipid Neuroterus anthracinus f. agamic on oaks Quercus spp. For some strange reason known as the oyster gall. Photographer unknown.

Patrol (left) versus defense (right) behavior by the black carpenter ant tending Disholcaspis galls on the southern live oak in Louisiana. The gall emits a sugary substance that attracts the ants, who then defend the baby wasp inside! #mutualism #biodiversity
