Moved
Moved from ID Request. The midge that causes this gall hasn't been named yet (or at least it hadn't when (1) was published), but it is in the genus Walshomyia.

Oligotrophus betheli?
These galls are sometimes tagged as this species on iNaturalist, but I can't find much information. Just curious whether you know more.

Not Oligotrophus betheli
As described and illustrated by Gagne (1989), the gall of that species is barely larger in diameter than a normal twig.
