Hello.
Chrysotoxum festivum is the correct name? Date: 2.7.2013, Slovakia-Kosice, 200m a.s.l.

Thank you for your help.
Regards, Karol.

The blackish species with this kind of antenna are festivum, vernale, lineare, and elegans. From the picture in the key, I exclude C. lineare, but I do not dare to say more...
