Gall Wasp second specimen - Andricus quercuscalifornicus
Eugene, Lane County, Oregon, USA
September 24, 2018
This is from a separate gall, due to accidentally dropping the original specimen and never finding it again. I wanted to include this image because the quality was better than some of the others.
This one was able to walk around after I pulled it out of the gall, so I think it was fully matured.
