No comments?
At the side-view I think to see something like hairy hump at the lower side of the hind leg. According to Kormann's book "Schwebfliegen und Blasenkopffliegen" (syrphids and conopids) this should mean that it's a P. frutetorum. Is my interpretation correct?
Best greetings
Rupert

As far as I can recall that character applies to males and I think this is a female...

Thanks, Paul, for this somehow frustrating information. Not so much frustrating, that I probably won't get the exact species of this fly, but more that again I was trapped by this book (Kormann), giving characteristics without a hint on their dependence on the fly's sex.

How do you know it's a female? (or do you really only think so?) Looking at the pictures of the male P. versicolor in the gallery, the eyes of this genus don't seem to give the information that they do about most of the syrphids' sexes.

still frutetorum seems the right ID ;)

Thanks a lot, Andre:D!
Could you please tell me by what characteristic you know that? When I find the next one, I'd like to determine it by myself. B)
