Is this Helophilus pendulus? How can I differenciate Helophilus pendulus from other similar Helophilus?
Thank you

Yes, it is a male of pendulus!
It's face has a black stripe, so no trivittatus! The hind margin of tergite 3 and 4 are yellow, so no affinis. The hind margin fron tergite 2 is black above the small yellow band, so no hybridus.
That leaves us with Helophilus pendulus! :D

Also, the 3rd femur is partially yellow and 3rd tibia abour half pale which excludes
affinis and
hybridus.
