Goldenrod gall fauna, larva

Horsham trail. Horsham, Montgomery County, Pennsylvania, USA
September 12, 2009
Size: 2.5 mm
I found some pedicellate galls on goldenrod (species Euthamia graminifolia). These ones were on flowers, not on leaves as the previous one.
I also found a cluster of what appears to be several parasitoid pupae in another flower gall and a tiny mite in another gall.

Update, 10/20/09: Although these larvae were found inside the galls of Rhopalomyia pedicellata, there is no way to tell their ID. They may be the midge or the parasitic wasp, according to Dr. Netta Dorchin.

More on goldenrod galls fauna.
