Found those two sp. in Israel.
They both found in the same place so I think they are the same sp. but still there are some small differences.

Hello!

I don't know if there are additional species in Israel. Here in central Europe they would be undoubtedly Episyrphus balteatus.

Thanks Juergen,

The tergite coloration looks a bit diffrent. if all Episyrphus has such color variation what is the main characteristic which used to identify Episyrphus?

As far as I know there are only one Episyrphus species in Europe.

Does this apply also for Israel?

The colouration and broad of the bands are rather variable (the narrower light bands are often silvery), but the overall pattern is indistinguishable for Episyrphus balteatus (in rare cases there are some melanistic individuals, though). This migrating species is one of the most numerous hover flies here :) from February to November (also called "winter hover fly").

yep. E. balteatus. They can have a strong variation in abdomen. :P

So I guess this one is also E.balteatus? a male?

Anyone know if there are other Episyrphus sp. in Israel?

I know! :)
There are no other Episyrphus species in Israel.
There are other species in the genus, but these are found in Oriental and Austalian part of the world.
Episyrphus balteatus is nowadays cosmopolitan, found almost everywhere!
