parasitoids - Aprostocetus - Male Female
Sunol Regional Park, Alameda County, California, USA
Size: 2mm
These wasps emerged from these Dryocosmus dubiosus galls. They are not cynipids but parasitoids. They emerged on 12/19/2007, but they've been inside my heated house so I'm not sure that these are good dates for when they would emerge outdoors.

Eulophid Wasps
This "courtship" behavior of the male is strikingly alike to the one of, e.g, Paper Wasps (Polistes). Only forewing venation and 4-segmented tarsi dinstinguish such Eulophidae from otherwise very similar Pteromalidae.
