Hallo again,

Though I examened all the 15 pages about Syrphidae in the Gallery, I could not find this one.

I found it some days ago (10th of June) in Southern Germany, 700 m over sea, in a Garden with a pool near the pool. I think it was about 1 cm, but I am very bad in guessing the length.

I am sorry, the photo is not better, but I hope the pattern is so clear, that somebody will recognize it.

Thanks at any rate,
Siga

Chrysotoxum bicinctum, male, I'd say.

My guess would be Chrysotoxum bicinctum, male.

There are many similarities, but (because I do not know) can the pattern differ so much.

I have the idea, that "my" fly has longer wings, and I am missing the brownish in the wings too.

of course, if you know for shure, but I think you don't do you?

Greetings, Siga

Right, I don't know anything for shure and I'm no expert.
But M. van Veen whrites that:
- in flight it can be confused with Dasysyrphus tricinctus
and it is not D.t.
- tergites 2 and 4 with distinct yellow bands. If other tergites with yellow bands -> var. tricinctum

So, if these fine lines are bands, yours is Chrysotoxum bicinctum var. tricinctum (I think)

With regards
Maja

So, if three persons agree, that it is a Chrysotoxum bicinctum, and noone disagrees, I have no problems to accept. In fact, I too see the main difference to the pictures in the Gallery in the additional stripes. And the two pictures in the Gallery differ in the amount of yellow stripes too.

So, thanks again for your help.
