SeasonalityJuly. IdentificationThis is perhaps the most frequently encountered species of Dicerca encountered in the aspen forests. Beetles are black, sometimes with a bluish tint. Elytral striae are complete to the apex, but sometimes weakly impressed. The mesotibia of the male has a distinct tooth. A similar species, D. hesperoborealis, may be separated, by examining the median carina (ridge) on the plate just before the hind coxa. The ridge lacks or has a very weak groove on one end. On beetles of D. hesperoborealis there is a distinct groove.
