I found quite a few of these on a park bench under willow oaks; most were apterous and this small but there were a few that were larger and fully winged. The gall in the thumbnail below appear representative of those found in the tree immediately over bench. However, I don’t know that the wasps came from these galls or how old the galls are.

Thanks in advance for the help



The two cynipids in the thumbnails below were found on the same bench at other times
