You guys are great! Thanks for the help with identification.

 
I just got an email from Ray
I just got an email from Ray Gagne, and he wrote:
"In my notes for my red book revision, I see that someone has already sent me spns from California and that the gallmaker is evidently new to science. Ray"
Did you keep some in alcohol?

 
Specimens in alcohol
I did not collect any specimens, but I could recover the acacia branch and the old galls if that would be helpful.

 
If you do not have any fly sp
If you do not have any fly specimens, the pictures are excellent for documenting the host relationship! Thanks a lot...

 
If you do not have any fly sp
Okay, I'll let them be, but the site is slated for development in the next year or so, and if so, I'll collect the branch and galls at that time. If anyone needs full-resolution images, let me know.

Subfamily
The gall midges proper are subfamily Cecidomyiinae and these can move to that page(1). The other two subfamilies are really fungus gnats and do not form plant galls.

Thanks for your help with the identification. I was thrilled to find they guys emerging!
