Hi again,
unfortunately I don't know how to distinguish between these two species. I tent to
E. corollae, but am I right?
Found: Germany, Lower Saxony, Göttingen, 250msm, in town on Campanula, 16.06.11
Thanks for comments, Christian

Hi, Christian!
Should be better to put Syrphidae questions in the Syrphidae subforum to attract the specialists...

I am no expert, but in
E. corollae males the yellow markings are connected in the middle. So this is a different species. Not sure, whether
E. luniger or another. Better wait for the experts.

In
E. corollae the yellow markings reach the tergite margins, in
E. luniger they don't. It is not clearly seen here, but I tend to
E. luniger.

I think this could be E. lapponicus, strongly bent R4+5 vein and there doesn't appear to be any yellow at the sides of T5.

That's right - the "ass" ist too black for
E. luniger! There is another quite similar species,
E. bucculatus, but it should have "tergite 5 with black spot at middle but lateral margins of tergite whole pale" and a dark oral margin that is, however, not seen here. So
E. lapponicus sounds quite good. The pictures of Wolfgang Rutkies (
http://www.rutkie...ister.html) have narrower yellow markings, but I do not know the range of variability.

I think spots can vary in shape in any Eupeodes, the feature which should make this E. lapponicus along with black margins on T5 I think is the strongly bent R4+5 vein. I'm not aware of this is any other Eupeodes species.

Hello Juergen, Sundew and blowave,
thanks a lot for trying to identify my fly. Here I have another pic of the same specimen more from behind. Maybe it helps. But
E. lapponicus sounds good for me :-)
Cheers, Christian

In addition to this male some days earlier (03.06.11) I got a female, that I IDed as
E. luniger. But maybe its the same species as the male?

Hi Christian,
The female is E. luniger, it has yellow at the sides of T5 and the R4+5 vein doesn't have the dramatic curve.
I've copied and cropped one of your pics to show where these are..

OK, thanks again for the very fast confirmation of the female.
