California Gall Wasp (Andricus quercuscalifornicus)? - Andricus quercuscalifornicus

California Gall Wasp (Andricus quercuscalifornicus)? - Andricus quercuscalifornicus
Mt. Hamilton, CA, Santa Clara County, California, USA
October 31, 2008
Size: 4mm
I'm pretty sure this is a California Gall Wasp (Andricus quercuscalifornicus) but am looking for confirmation. My ID is based on the gall. After years of seeing these galls, I found one that was "fresh" and still intact -- no exit holes. I took it home and put it in a jar for a few days. Magic! This picture shows the exit hole along with the little wasp that emerged. I'm uploading a separate picture of the gall, too, since you can't see much here.

These are very cool images...
It's really neat to be able to see the relative size of the wasp to its host gall. I hope you let it fly free after it finished its photo session. (Wish I could help out with the ID...)
