Just noticed that the front tibia is dark ringed at the apex, not in the middle, which might be more like atricapillus. Not sure.
Edit: Not an important point, but interesting that my ID does not outweigh yours, when I am 'sure' and you say 'might', and when my reputation is ahead of yours. Never quite follow the whole reputation thing!

I agree, there should be more clear dark spots on the middle of the tibiae. But also the shape of the ovipositor. M atricapillus the cerci are longer thinner and very often point downward more then the case is with M cingulatus.
..somewhat embarrassing, in my case.
I've noticed that before, I got the impression it favors species over genus over family etc
I noticed the white hairs, though cingulatus is a new one to me. Worth collecting a female, or wait for a male?

They aren't going to be around for much longer, so gather ye asilids while ye may, or words to that effect.
Females are easier up close, where the frons hairs and sternite bristles generally make them easy enough to tell apart. Like all these, a few specimens helps to sort out the differences, though. The 'British Soldierflies and their allies' key to these (and cowini) was updated in Dipterists Digest a few years ago...some can be tricky.
You might be right about the species v genus reputation thing. It doesn't matter, anyway...just seemed different to normal, that was all.
I'll heed your echo of Herrick and get what I can. I've got a Syrphus (fem), male big and small cheilosia, a fresh C. 'verralli' - is there anything I can do with the microscope with Chrysotoxum or does 'tricky' in this case mean give up, or should I try and send it to a local expert. Roger Morris said they're tricky and best compare it with an elegans.. ?? none on ebay ..does that just mean keep collecting
It helps doesn't it, especially if you want to do it yourself. Otherwise, yes, find someone to send them to. I don't get your variety of Chrysotoxum up here, so have no specimens of those species.
