Hi,

A big one, around 12mm I think.

2nd October on Ivy, my garden near Lincoln UK.

3 pics + 1 crop

Looks like a female sarcophagid to me :) The eyes look too red and bare to be a Linnaemya :)

Thansk Chris, it was a little confusing because of that bristly face.

Could this be Brachicoma devia? I can't see the long arista on mine, but it does have strong facial bristles!

I'll change the title.

Doesn't 'feel' like Brachycoma (which has a very distinct yet hard to describe colouration of the abdomen). Moreover, the arista 'seems' to be plumose.

I'm thinking female Ravinia striata ?

Thanks for the suggestion Theo, you could well be right! Ravinia striata, or Ravinia pernix as it now seems to be named, is the only Ravinia species we have, or maybe anyone has?

The arista certainly are not bold on that species, I would think they are plumose on mine. I found some very good photos of it, showing the face and the bristles look to match up. It also has the frill of pale hairs/bristles behind the head.

I am not sure this is Ravinia pernix, and I am basing this partly on the colour, which is too bluish-black as compared to the more greyish colour of R. pernix, and partly on the rows of frontal bristles, which I interpret as diverging abruptly anteriorly [difficult to see, though]. I would think this is a female Sarcophaga sp., and if very hardly pressed for a species name I would put my bets on Sarcophaga caerulescens, which is the species of British Sarcophagas, that in general is most dark and has that bluish 'whif' that also has given rise to its name.
