I found this fly today in my house. Several minutes later it was dead. Is it Empis sp?

No cubital vein fork that I can see: therefore Rhamphomyia (s.l.)

Rhamphomyia (s.str.) of the
sulcata group. Might well be
R. sulcata itself.

What characters are necessary to determinate the species? Because it was already dead, I have collected this fly. Thanks for the answers.

Mainly the genitalia.
R. sulcata is relatively easily separated from the other common two species in the group (
R. sulcatella and
R. cinerascens) based on the genitalia (if you know how to look at them). Separating the males of the other two species is more tricky. If you send the specimen to me with some locality details, I can identify it for you.

Ok, how do I send it? Conserved in alcohol? Can I send also another Empididae that was a few mm? I will take some photo's, but these aren't very clear due to the size.

If you can still store them in alcohol, fine. Otherwise, dry in a small tube with some material to prevent them from moving around. Address sent in PM.

A female of
Empis chioptera. Post your pictures here if you want. The
Rhamphomyia is
sulcatella but more probably
cinerascens. I need to check with some drawings I have at home.

Thanks for the effort. The photos of the Empis chioptera are unfortunately failed. That will teach me to look first at the photos on the computer.
