A blue Calliphorid photographed in Barnard Castle, County Durham, UK, on 2010-08-06.
I suspect it might be a female 
Melinda viridicyanea.  Can anyone confirm this?
My suspicion is based on the following reasoning:
It looks very similar to this female 
M. viridicyanea:

And to this 
Melinda sp:

But the scutum seems too hairy and the cross-vein on the wing too straight for this female 
Protophormia terraenovae:
 
http://diptera.in...to_id=2132
There are only 2 Melinda sp on the UK list: 
M. viridicyanea and 
M. gentilis.  The photos in the gallery suggest that 
gentilis is less blue the fly in my photos.

It is a Melinda indeed and both are very similar.
Colouration is not very constant in Calliphoridae, I would not rely on that.

Thanks Theo.  I'll just call it a Melinda sp. then, and I'll remember that point about colouration.
