Moved from Flies.

Good find. Some Catochini have been recorded on snow in winter. I need to find more and more modern information.

Note the barely visible forked M vein.

Any other angles needed?
John, I still have this gall midge. Are there any other pictures I should take to help in identification?

Other angles
Closeups of antenna would help -- count of segments, shape of fifth segment, and hairs.

Secondarily, confirmation that there is no empodium between claws and head has three ocelli.

Genitalia, preferably from above.

In Insects of Connecticut it seems to come out at Eucatocha barberi (Felt), a species recorded in winter.

Other angles added
John, I added a couple more pictures that show most of what you're asking for. Hopefully they're good enough to go further with the ID.
