Hello!
I found this hoverfly in easily damp woods (predominating deciduous trees but also conifers) on the Swabian low mountain range (Baden-Wurttemberg/Germany) on 700 msm on June 9th, 2009. It is for certain a species of Cheilosia. Can one determine her with the photos more nearly?

The eyes are occupied with fair hair, black hair is on the forehead. The sheer stripes at the tarsi of the hind legs and the bright tarsi of the forelegs are conspicuous.

Size about 8-9 mm

She looks a little like Cheilosia semifasciata...

Best regards
Andreas

This photo is very blurred but one recognizes the bright front tarsi.

Ch. albitarsis:)

But sure! I had listed even all important details there and have not come onto it nevertheless ... Which disgrace.

In my opinion this is not Cheilosia but Melanogaster. You can clearly see the contrast between the shiny sides on tergite 2-3 and the shiny tergite 4 and the dusted centre of tergite 1-3. Wing venation excludes Orthonevra.
The long hairs on the genitals of this male exclude Melanogaster nuda, i should check the key to see if one can exclude other species.

---

I am confused now ... The genus Melanogaster is me completely unknown and he also is not in my old determination key contained. I can therefore say nothing at all to it. To this genus, I find as good as nothing also on the Internet.

Is there perhaps still another opinion on it?

Best regards

here you find a lot of syrphid pics, as well in collection as in the field. Maybe in your old key Melanogaster is still concluded in the genus Chrysogaster (or was it the other way round?). the dusted middle parts and shiny sides on the abdomen are typical for the genera Chrysogaster, Melanogaster, Orthonevra and Riponnensia.

I have now investigated for a long time and not found a solution anyway. This hoverfly remains uncertainly that way with the reference to Melanogaster.
Many thanks, even if a clear determination was not possible.
Also thank you for the interesting link.

Andreas

Do not argue! It is 100% Cheilosia albitarsis!:o

---

I agree with Vladimir,
Certainly a male Cheilosia, and almost certain C. albitarsis!

Hello Vladimir, Hello Gerard

Many thanks that you resolve my confusion. The thing with Melanogaster upset me completely.

Therefore it is Cheilosia albitarsis anyway!

Best regards
Andreas
