Cecidomyiidae:
Catocha species formerly placed in genera
Eucatocha and
Anocha are found in winter, often on snow. See BugGuide:
http://bugguide.n...iew/398300. They have very large wings. I don't know whether large wing size is adaptive for cold weather.
Other genera commonly found on snow are
Chionea and
Diamesa.
