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 ....' etcCheers 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 Theo |

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. Liekele |

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). Liekele |
