These are surely flies from the family Sepsidae. I can't see spots on wings,    but if there are some spots, then you have genus 
Sepsis. ;)

There do not appear to be spots, so that really leaves the genera 
Nemopoda and 
Themira. By the over-all colour pattern, I assume the first, possibly 
N. nitidula.
