Sericomyia

Thanks Bjoern. I appreciate the id. How can you tell it is a male? Are they dimorphic? Or is there a visible ovipositor on the female?

male have holoptic eyes, mean

male have holoptic eyes, meaning the eyes meet on top of the head, females are dichoptic, meaning the eyes are separated on top of the head. Works for many Syrphid genera, but not for Helophilus...
