Hi Black,

My guess would be Chamaemyiidae. Nice picture. This would be a nice one for the gallery (but let's first make sure to which family/genus/species it belongs).

I've got in my use fly itself, collected by Black after photografing.
It is difficult for me to decide wheather pulp is yellow or dark.
I think dark. If so, it is Ch. emiliae - yellow t and tarsus, and visible even on photo yellow spot on antenae 3-d right near arista base.
If pupl yellow - it is Ch. polystigma.

I think there a very, very few species of Chamaemyia that can be identified to species level on the basis of pictures like these. The genus is notoriously difficult... Sad
