~3 mm body. On a cloudy 90 degree F day. Maybe Colotrechnus based on white wing venation. Needs expert review.
Tossed up the blacklights for a bit this evening to see what would show up. Several things did! :)
Emerged from whitefly nymphs on greenbark ceanothus (Ceanothus spinosus).
On Q. shumardii
A couple of these wasps emerged today from this Neolasioptera cornicola gall I collected.

On Red oak group tree.
Found dead on the surface of the water of a fountain. I collected the specimen, so if other details are needed I can provide them.
