I often see these on top of straw bales in the morning.
I take the photo on 24 March 2014 Kokkola, Finland.

Thank you John!
Copromyza stercoraria makes sense. It’s more common in the area.


I then captured the fly, brought it home and took more shots after needling it.

Looks like Copromyza, indeed. Dust pattern on anepisternum (mesopleuron) seems to indicate equina.
