Cecidomyiidae
The fly on the gall is definetly a Cecidomyiidae
(Supertribe: Cecidomyiidi)female, possibly a newly emerged fly from the gall. The host plant is now known as Ageratina altissima, it is no longer Eupatorium rugosum.
There are three genera of gall midges which produce galls on Ageratina here in Allegheny Co. Pennsylvania: Neolasioptera, Schizomyia and an Asphondylia. Its hard to tell from the photo which genus to place this gall midge.
