Cecidomyiidae, gall on Goldenrod - Lasioptera solidaginis

Cecidomyiidae, gall on Goldenrod - Lasioptera solidaginis
Mike's Road Ditch Prairie, Winneshiek County, Iowa, USA
September 5, 2015
Although the gall description doesn't quite fit (this gall was too full),
perhaps Lasioptera solidaginis as per Gagne's RedBook, page 157
September 12, 2016: Lasioptera solidaginis as per R. Gagné (Thank you!)

September 5, 2015: collected gall on Goldenrod, Solidago canadensis
April 20, 2016, on/before: emerged, 1 larger wasp, 2 smaller wasps
April 30, 2016: cut open gall, full of life, including 1 larva, 2-3 fly pupae, sacks with communal wasps almost ready as adult wasps
Taped the gall back together as best I could
May 2, 2016: in container, more live small wasps, 1 dead gall fly (spent pupal case still partially in the gall but fell off)
May 4, 2016: larva was out of the gall, photographed and now in alcohol
May 6, 2016: adult emerged
I think the larva and the pupa are the same species as the fly.
