Another parasitic wasp in goldenrod gall - Platygaster

Another parasitic wasp in goldenrod gall - Platygaster
Prudential campus, Upper Dublin, Montgomery County, Pennsylvania, USA
September 20, 2009
Size: 1-1.5 mm
This is the center of the gall shown in the other picture. There is a lot of frass, perhaps left by an inquiline moth. Some caterpillars use galls like this. The shiny material near the top of the gall is probably the remnants of cocoon shells made by the parasitic wasps. More than a dozen wandered around when I opened the gall (see the adults in the other pictures). Comments by Dr. Netta Dorchin
