Similar Species

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).
