Suggested I change title to Sarcophagid to catch the experts
Still having trouble spotting any differences with these, can anyone identify it for me please?
Taken in southern UK, 1/7/2010.
Thanks

Hi, there have been ~50 views but no responses so I just wondered if that was because the photos aren't suitable for identification or just that someone who knows hasn't looked yet, or whether because I have 'guessed' at Muscid I have only attracted the muscid fans and it isn't one? So any comments would be appreciated (eg 'not a muscid try broadening your search to ....') etc
Cheers
Nick

Change title to Sarcophagid or even Sarcophaga

Hmm, it's not
Sarcophaga carnaria/
variegata group - it'll be one of the other, smaller species that are going around at the moment. I am catching lots but I haven't tried identifying them yet - I usually do that in winter when I have more time. Sadly, the features that identify Sarcophagini tend to centre on the tip of the abdomen or the genitalia, so its not easy to distinguish much in photos. :)

Little doubt it is Brachycoma devia, this silvery colour

You mean the colour is silvery-blue, rather than yellowish-grey dusting?

My first impression was Brachicoma as well.
It is indeed a silvery-blue colour that distinguishes this genus from Sarcophaginae, even in the field.
Specimens are easily recognised by the row of strong parafacial bristles.

Thanks for all the replies - I searched the forums for Brachicova Devia and found this post http://www.diptera.info/forum/viewthread.php?thread_id=1932&highlight=Brachycoma+devia&pid=8001#post_8001 (I hope that works!) where there is discussion about palpi and arista so thought I'd see if any of my photos showed anything helpful - I'm not sure but I have attached a couple more photos of close ups of the head - not very good quality but might help?

It does look like it has some strong parafacials (mine all have the same comb-like row of parafacials) ... and wow, look at the hairs on those palps! :)
That's an interesting feature that I don't think appears in my keys ... it's a nice one to know :)

Brachicoma it is.
Most likely Brachicoma devia (Sarcophagidae, Paramacronychiinae).
