Possibly a parasitoid of Vitisiella brevicauda
Pelham, Hampshire County, Massachusetts, USA
June 15, 2011
Size: 1.2 mm
On June 12, I was given a bag of Vitisiella brevicauda galls on grape (Dr. Gagne confirmed my ID of the galls; formerly in the genus Janetiella). By the end of the day, many bright orange midge larvae had emerged, and I put the bag in the fridge until I had time to deal with it. This morning (June 15) I found about 85 midge larvae in the bag, plus this one little wasp. Could it be a parasitoid of the midges, or is it just an innocent bystander?

Encyritid…
There are records of biting midges being parasitized by encyrtids - whether this occurred in this case is yet to be determined.

See reference here.
