Description:

A dead fly found floating in a rain filled sheep lick tub on moorland. There were some really tiny orange mites onthe surface of the water also, one is visible in this crop. I do not recall exactly the size of the fly but it might be identifiable by the distinctive head? Thanks.

Thanks Ian, I haven't begun

Thanks Ian,

I haven't begun to look at diptera in much detail. It does look like some others in the carousel. It seems to be a broad and varied family?

Empididae

Yes, quite a large and varied family, with just over 200 species in Britain. There are some downloadable keys produced by Mike Hackston:

I haven't tried them out yet, but they look promising.

Hi Martin, Thanks for the

Hi Martin,

Thanks for the link. I had a look there at the genus Rhamphomyia. This is a very exacting branch of entymology. The details are minute. I'm sure you are correct- I need to do more studying to pick out the venation detail.

Empid

I thought I could see a fork in R4+5, but therein lies the problem from photos!

Those keys, based on Collin, are very good. I use some of them quite a lot...the illustrations are very useful.

venation

Apologies Ian, having zoomed in on the photo further I agree with you that there does appear to be a fork in the vein, so I think Empis is a likely option, and it's not Rhamphomyia.
