One of four boldly-marked flies in this family - grey with black spots on the thorax. A. imbrida has slightly different-shaped markings on the thorax - an indentation on the hind lateral black spot - which distinguishes it from the other species. It also has more numerous (typically 9-15) anterodorsal setae on the hind tibiae and hairs on the arista are only as long as the basal diameter of the arista (these hairs are slightly longer in A. procellaris and A. bazini)

Other Anthomyia species.
