Anthomyia procellaris - Anthomyia procellaris
This is quite a handsome little fly, its thorax being neatly marked with black on grey. The abdomen is also greyish.
There are other similar species and certain identification requires detailed examination, if we cannot be certain that an image is Anthomyia procellaris but it is likely to be this species, it is highlighted in a red box.
Anthomyia procellaris is very similar to A. imbrida and A. pluvialis. Pluvialis can normally be distinguished by the dark mark at the base of the wings being divided into two separate spots. In procellaris and imbrida this is fused into one connected spot. In procellaris this spot has a straight rear boundary wheras in imbrida it is more notched. It is also useful to count the anterodorsal setae on the hind tibia (males), there are 9-15 in A. imbrida, less in the others. (Note that A. imbrida has not been recorded in Leics and Rutland).
Well wooded areas. It is often seen sun-bathing on fences and posts and feeding on bird droppings.
This species is not well understood but is thought to have an association with birds' nests.
Scattered records from England and Wales.
Status in Leicestershire and Rutland is not known.
