Anthomyia sp for ID

Submitted by colinleb on

Bit surprised to find this male fly in bottle trap baited with chicken to sample, particulary, Calliphorids.  Beds.  Suburban garden.  Some time between 21 - 30 April 2020.  I think it is Anthomyia sp., possible procellaris (although there are a couple of very similar species).  Is it possible to confirm ID from these photos please>

Thanks Nigel.  Via e-mail I have also had confirmation from Michael Ackland that this is Anthomyia procellaris.

He has also sent the attached photos to show the difference between males of the three similar species A. pluvialis, A. procellaris and A. imbrida, with the following notes:

"My intention is not only to supply a name when I am asked to ID an antho, but to make further use of the opportunity to offer the reason or characters which might help in the future, and I think this is much more helpful. (if I can). 

The shape of the lateral postsutural black mark (lateral view) in the males of Anthomyia pluvialis, procellaris and imbrida can almost always be separated by the hind margins of these black marks. In pluvialis it does not reach the thorax margin, in procellaris it does, and in imbrida it has an indentation."
