Moved
Moved from Hickory Gall Midges. ID based on Gagne's 2008 Caryomyia monograph, in which this species is described for the first time. From his photos it is clear that C. inanis galls do not resemble this.

Moved
Moved from ID Request. This is a Caryomyia midge gall, and there are several possibilities for species. If you were to cut it in half and find a transverse partition inside, we could safely call it C. inanis.
