In flight this looked like a dark E. balteatus to me, but when it settled, I saw it was not. I am not an expert -- is it an E. eligans? Are their males duller and hairier than females?

Yes, I agree with evergestis - Epistrophe eligans looks different.Your picture is quite challenging  Do you have also a lateral view? Matej |

As far as I can make out, it's dull adomen is the only remarkable thing. I checked my collection and E. eligans is just as hairy as shown on the photo. It matches Epistrophe eligans in: the angle of the eyes, the dusting of the frons, the length and colour of the hairs on the body, the lenght and colour of the stigma, the pattern of abdominal markings. So I'd say Epistrophe eligans, abberant specimen which has a dull abdomen. It is a rare thing, but well noted. Abberations in Syrphidae or other Diptera families. Melanostoma mellinum can have an entirely black abdomen. Episyrphus baltetaus, Platycheirus sp, and Parasyrphus too. Bombyliidae are famous for abberations in wing venation. Just last week I was sent a Gymnochiromyia with on the left 5 and the right 4 fronto-orbital bristles. It should have three either side. Greetings, Ectemnius |
