Goldenrod maggot - Rhopalomyia solidaginis

Goldenrod maggot - Rhopalomyia solidaginis
Pennypack Restoration Trust, Montgomery County, Pennsylvania, USA
October 3, 2008
Size: 1 or 2 mm.?
The bunch gall is made by the fly. I found several galls occupied by these beetles in a couple of different occasions and in different places, so it must be a common thing. Did the beetles do all the damage?
The gall maker
More of these beetles. There are also some caterpillars found often in the goldenrod bunch galls; that is why the gall maker is considered an "ecosystem engineer", it creates habitats for other species.
