"Little Black Fly" - Drymeia - Female
~3,700m, upper Tundra Trail, Rocky Mountain National Park, Larimer County, Colorado, USA
July 19, 2005
I think it may be an Anthomyiid of some kind, found here on Geum rossii (Alpine Avens). Anyone with more experience dare to take a 'stab' at an ID?


A lead
I got an ID for a hairy black fly from the summit of Mount Evans.

I have no idea what genus names would be used on BugGuide for this group. By one classification Drymeia (including Pogonomyia) is apparently the second most common genus of Muscidae on alpine flowers in the Rocky Mountains. (Kearns, C. A. 1992. Anthophilous Fly Distribution Across an Elevation Gradient. American Midland Naturalist 127(1):172-182)

Very interesting -
Thanks, John for this! Will have to wait a bit since I just returned from watching numerous geysers in Yellowstone. Also took some insect photos I'll post some time later.

Moved from Tachinidae.

This is in the family Muscidae

Thanks, Norm, it looks like I was a bit hasty in moving some of these calyptrates. I'm glad they're being looked at though.

Moved from Flies.

Looks good
Have you seen this Canadian image, which includes a good wing view?
