Syrphidae_Xanthogramma pedissequum (male) is the correct name? Region Malá Fatra Terchová about altitude cca 500 m a. s. l. Thank you very much for your help. I made a photo of 17.05.2013.

I think there is two pissibilities: X. pedissequum or X. dives...
I'm not able to go to specie !

The dark mark below the stigma continues distinctly below radial vein R2+3, and the wing tip is not infuscated, so
X. pedissequum seems to be the better choice.
There is a
Xanthogramma key in the net (

X. dives in

Fero, one crucial thing is missing at your pictures - a membrane connecting tergites and sternites, i.e. side view from "lower perspective". In case of X. dives it should be yellowish, in cas of X. pedissequum it should be greyish.
