Agromyzidae on Goldenrod - Melanagromyza - female

Agromyzidae on Goldenrod - Melanagromyza - Female
Mike's Road Ditch Prairie, Winneshiek County, Iowa, USA
Size: 3- mm
September 5, 2015: collected 3 stem galls of Goldenrod Gall Flies, Eurosta solidaginis, on a plant of the Solidago canadensis complex
March 14, 2016: a small fly dead at the bottom of the rearing jar
Must have been a mine in at least one of the leaves but the photo of the green galls with leaves didn't show it.
See comments below: "presumably a stem borer"

Agromyzidae on Goldenrod - Melanagromyza - female Agromyzidae, lateral - Melanagromyza - female

Moved
Moved from Ophiomyia maura.

Owen says this one is a Melanagromyza, so it was presumably a stem borer. Not identifiable to species, since it's a female.

Might also have been a stem miner
I reared a female Ophiomyia last year from a stem mine on Canada goldenrod. I still think it might be O. maura; had the same blue-green puparium.
