Photo taken in Reading, UK, on 2009-11-05.
I think this is a male Helina evecta. Am I correct?

It looks just right to me, but H. annosa is only distinguished from it in the key by the bristles below the hind femur, which we can't see here. A good lateral view might settle it.

Unfortunately this was the only photo I got of this fly. The NBN Gateway data (http://www.dipter...0000005368 and http://www.dipter...0000030832) does suggest that evecta is much more common than annosa in the UK, so I will put it down as Helina cf evecta.
Thankyou Stephen.

It's true that I see lots of evecta just like this here in Lancashire but I've never found annosa.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
