Hello flyforum,

No, I didn't drink to much.., I found some flies with 'redwine' colored-eyes.
These kind of flies I didn't see before this year.
I think it are Phaonia sp., maiby rufiventris?

eyes nice oval-rounded and
dark-red
femur and tibia yellow(braun), thorax and scutellum yellow(braun)
eyes close together(male?)
no sharp corners in M1 vein in the wing

greeting, Robert

In my reference collection this matches only Phaonia subventa (Harris).

EDIT: Phaonia rufiventris is also close, but it has a darker, less striped thorax and very narrow black bands across the abdomen on the margins of tergites.

I thought P subventa had a dark median stripe down the abdomen. Does this mean it is a variable feature, or have Nikita and I identified our specimens incorrectly?

In my collection too (some verified by Adrian Pont:p) it is subventa though it's called variegata (Meigen, 1826) the old but not older name for Phaonia subventa (Harris, 1780).Very narrow black bands. I'll try for photographs to illlustrate both of Kahis very well observed characters especially the abdomen bands.Only some specimens have the dark median stripe mentioned by Susan which I too thought might be a character. These flies are very difficult without chaetotaxy (see glossary soon).
