Be on the lookout for stem gall Diplolepis ashmeadi on Rosa nutkana!

Everybody! Just found out this gall existed! Be on the lookout for stem gall Diplolepis ashmeadi on Rosa nutkana! And maybe on other roses too! Only two observations in iNat! One in CA and one in OR!

Hi everyone again,
This is unrelated to D. ashmeadi but since you are all interested in finding new galls, I’d like to mention another one called Dryocosmus demartinii. It’s a gall wasp species on Golden Chinquapin (Chrysolepis chrysophylla) newly described in 2018, and iNat still has no observation. Who wants to be first? Here’s the detailed info:

Adding @graysquirrel and @beartracker because it’s likely on your turf :)
If anyone finds it, please be sure to tag me!

Hi @chyroptera, is there any chance that you can collect this species of gall, or other Pacific Coast rose galls aside from D. rosae and D. californica? @stephaniesq and I are trying to revise this genus, and there are some specimens that we definitely want more of. If you or anyone is interested please let me know, and I can tell you more about it? Thanks :)

We are particularly interested in:
