Photos taken in Reading, UK, on 2012-06-10.

Any ideas for the family?

How about Cinochira atra?

Thanks. I'll change the title to attract the Tachinid experts.

No, not Cinochira ... in this photo the median vein is not shallowly curved towards r4+5. Looks like Muscidae to me :)

Thanks, Chris. Another change of title...

On closer scrutiny, the anal vein does appear to meet the edge of the wing, therefore Anthomyiidae (abdomen also appears antho-like).

I always thought orange colour on the frons was a way to tell if it was an Antho or a Muscid, without the need for any other visual clues. Maybe someone knows differently. So an Antho..it seems.
Mind you, I have been wrong before...once or twice...well more actually!!

Sorry Roger, but the colour of the frons is of no value, anthomyiid frons can be all black or all yellow/red, or inbetween. I can''t offer any ID as I can't see the details, but it is about the right build.

Thank you everybody. I didn't really expect a species, nor even a genus. I just thought this fly looked a little odd among my other unidentified Muscoids.

On picture 2, one can distinctly see the anal vein reach the wing border, thus, of course, Anthomyiidae.
Muscidae very rarely have (some Coenosiinae) an orange anterior part of frons (or it is entirely orange in orange-bodied species), so it remains a good clue on the field.
