Moved

Moved from Flies. The size must be an overestimate.

We now have all (both) of the American Canthyloscelidae.

Unk Insect

Thanks Yurika, this looks very close. I may have messed up on the size. A friend tells me the Potentilla is about 250 mm across. If that's true for this species of plant then Our insect is less that 8mm. That comes close to the 5mm guess in Ron H's pictures: http://bugguide.net/node/view/262758
The narrow female head also fits. I cannot make out the veination in the wings.

march fly?

I think you've got an all-female swarm of march flies, something like this:

but the season's a bit off.
Please wait for an expert, though.

March Fly?

Thanks Sara,
The antenna on mine are a bit long. Perhaps a March fly with long antenna. Also mine is very tiny and was photographed on a Potentilla at a high altitude. Perhaps it is mid Spring at that altitude. Maybe more like a Dark-winged Fungus Gnat. What do you think?

Unknown Insect

This is a totally weird insect. I notice that the cerci are short and the abdomen is slightly turned up in some specimens. The tiny head compared to the thorax should be a good clue as to its identification.
What about a small black stonefly?
