Photographed on Mint flowers in my garden, here in Ipswich, East Suffolk, on 7 Sept. I've keyed it out to Rhamphomyia sciarina (female) using the M G & V A Hackston key at
http://www.record...tedkey.pdf Is R sciarina right?

Regards,
Martin

I thought the only species in the group in which the female has a greyish mesonotum is culicina.

What about Rhamphomyia variabilis?

LoL, I never even considered any further than species with acrostichal setae. This one has none so, yes, this is variabilis.

I thought it was yellowish but I've little experience. Now I see what you mean! I've had another look at the key, and at some photos of R sciarina and variabilis, and agree that with the thorax more grey than yellow and no acrostichial bristles this isn't sciarina but variabilis. Thanks to Paul and empeejay for correcting my mistake.

Best wishes,
Martin

I just saw in the key that "male often with velvety black thorax, while that of female
is greyish black or grey", so this is a female, isn't it?
