Hi,
There are multiple species in your photo. I think I can recognise three species, Episyrphus balteatus, Eupeodes corollae and E. latifasciatus.
Best, Jonne

Episyrphus balteatus ist the one more orange looking specimen in the front. The three other males might all well be
Eupeodes corollae, at least the ones in the background and on the right hand side are. The left male has a a yellow band of connected spots on tergite 3 (and 4), but
E. corollae males can have that, too. To make sure that it is really
E. latifasciatus, we must find out if those yellow bands are fully separated from the tergite side margins by a narrow black strip (see
https://www.flick...787790503/). That is impossible to decide from your photo. So I would say cautiously that you have only two different species here.
Regards, Sundew
