Hello,
I found this 8 mm male last night at our door lantern. Because of the strongly hairy eyes I first thought of a
Polietes, but it seems to be a
Helina. At first the abundant
H. evecta comes into mind, but this fly seems to have bare aristae. Possibly the rare
Helina annosa?

Hallo Jürgen,
I think
Helina is correct but we cannot decide whether it's
evecta or
annosa:
Manual CE Muscidae (Gregor et al)
annosa:
"Eyes densely long haired, arista long plumose..."
evecta:
"Eyes densely long haired in both sexes, arista long plumose..."
and in the key:
"
- Hind femur with strong anteroventrals confined to distal half;
scutellum almost bare ventrally =>
annosa
- Hind femur with a complete row of strong anteroventrals confind to distal half;
scutellum setulose ventrally =>
evecta
"

Thanks a lot, Eric! Then I remembered it wrong, that the arista in
H. annosa is bare. :|
