Appearance
"Anthomyia procellaris" can reach a length of 5–7 millimetres. These small flies show velvety black on greyish markings, with three black spots on the center of the thorax. The eyes are bare and the proboscis is robust. The abdomen is mainly greyish.This species is very similar to "Anthomyia imbrida" and "Anthomyia pluvialis" and it is a quite difficult species to identify correctly. However in "Anthomyia procellaris" the black marking just at the base of the wings is not divided into two separate areas and ends in a straight rear boundary. Moreover in males the anterodorsal hairs on the hind tibia are less than 9.

Distribution
This species is present in Europe, the East Palearctic realm, the Near East, and the Nearctic realm.
