Calosoma lepidum
University of Alberta E.H. Strickland Entomological Museum Read more about this collection »
SeasonalityAdults have been collected in April to June.
IdentificationThis species, in the subgenus Chrysostigma, is similar to calidum, but differs on the following: The entire body is shorter, with broader elytra, which are almost constantly more or less rufinistic. Prothorax narrower, more constricted towards the base, basal foveae smaller, side margin more narrowly and less distinctly reflexed. Elytral foveae usually more numerous, smaller, not or very little broader than their interval, adjoining striae not disturbed; transverse lines of the intervals less deep and regular, particularly near the suture; all striae as a rule deeper. Length 17 to 23 mm.
