SeasonalityJuly. IdentificationSecond and third segments of the antennae are about the same size. The mesotibia of male is simple, or has a slight dilation. Elytra striate, becoming obliterated in the broadly punctured areas. The general body outline, is similar in appearance to beetles of Poecilonota cyanipes. There are two subspecies of D. callosa recognized by Bright (1987). No, good structural features for separating the subspecies were given except for relative size and geography. Bright reported both subspecies from Alberta. In my examination of the material, I recognize one subspecies, Dicerca callosa callosa Casey.
