The attached was photographed in South East England earlier this month. (Aug).

Having read the thred 'Little fly ... fly looking' dated 17/08/06 I suspect that this is a Phasia Sp. I was only able to get the one photo so hopefully it is sufficient.

Thanks

Regards
Gordon

Phasia it is !
See previous similar post.
Need a blowup of the head. Looks like Ph. pusilla in this case, though.

Thankyou Theo.

This is the best I can do for a blow up I'm afraid. Not alot of difference.

Would be better to see the hairs on the gena and the colour of the haltares :) Light gena hairs =obesa, dark =pusilla/barbifrons ... then dark haltares =pusilla and light haltares =barbifrons :)

Right Chris,
but with this angle the 'official' character would be most easy to see:
hairs on parafrontals in several rows -> barbifrons
bristles on parafrontals in one row -> pusilla (or, at least, subg. Hyalomyia).
At this moment, I'm more sure it should be pusilla

Yeah, given that it was taken in UK it is most likely to be pusilla anyway or a strange, undusted obesa. P.barbifrons would be good to confirm it possible because it would be a nice sighting - we get them reasonably regularly but they're still not 'common'. :)

Right.
Here barbifrons is common and pusilla to look for.
So let's change houses !
