Hello,
The photo where this detail comes from was primarily taken to show the flower structure of Oenothera tetragona (Onagraceae). When I took it in June 2006 my interest in insects was still underdeveloped, which has enormously changed meanwhile! So I would really like to know whether this fly might be a Sicus. Unfortunately, there is just this one pic, but the wing venation is well seen.
Thanks, Sundew

wow!!! lucky you! One of my favorite flies! Conopidae > Myopa s. :D

That's good news, dear Jorge - this genus was still missing in my collection. I wished I had more time for sorting my fly photographs, but the semester is too time-demanding at the moment. Sorry!
Warm regards, Sundew

Dear Jorge!

The characters are
- very long T2
- colour of the wing (light base, no spots)
- small frons + colour of frons
- Jizz

What have been your reasons to guess it could be Myopa? Which species could be possible?

Jens-Hermann

the frons seemed to me bulgy and the eyes seemed very smaller than the rest of head (typical for Myopa).
Myopa occulta has no spots on wings. :) the wings are clear too. But this couldn't never to be a M. occulta.
Maybe I was fooled by the way the frons projects. :S
I was thinking in M. dorsalis. :S the scutellum seems to be reddish; the colour of abdomen fits well.
I don?t know all Myopa. :) I just know these: Myopa buccata, Myopa occulta, Myopa picta, Myopa tessellatipennis, Myopa testacea.

Though I wished I had found a Myopa at last, I am inclined to join Jens-Hermann's opinion in this case. As the photo does not show the required details, and I have already seen Sicus ferrugineus in our area, let us take it for this species with a "cf."
Many thanks, Sundew
