It is shouting "Lydella" at me but I can't find any features that would confirm it ... maybe Theo could comment? :)

Yes, correct, you can see the erect apical scutellars in the second pic. The eyes are bare and the scutellum is black, so it can't be Phryxe.

I'd say it is a female L. stabulans, but females Lydella are pretty difficult to separate from pic.

Yes, the erect apical scutellars were fairly clear ... couldn't see a single hair at the base or r4+5 ... but the bare eyes and 'chin-less' face with wide frons were all making me think Lydella :)

Thanks, Chris and Theo, Lydella sp is quite good enough for me!

Just to add some context, Lydella stabulans is one of the commoner summer tachinids in the UK. Lydella grisescens would be a better find but they are hard to split from a photo :)

If the colours in the picture are any good, this can't be grisescens, this one is much too bluish.
