SeasonalityIn Alberta this species has been collected from late May to early September.
IdentificationAdults: 8.0-9.5mm in length which helps to distinguish them from C. sericeus sericeus. Entire dorsal surface usually bright metallic green but sometimes with a bluish hue, elytra subopaque; appendages rufo-testaceous, antennae infuscated frm the fourth segment. With the exception of the center of the frons, the head is coarsely punctate and pubescent. Antennal segment widening apicad, almost conical in appearance, especially near base. Microsculpture absent on head which also. aids to distinguish them from individuals of C. sericeus sericeus. Microsculpture of the prothorax is irregularly isodiametric and elytra are strongly granulate. Penis is short with a blunt apex. Adapted from Lindroth 1963.

Presumably omnivorous.
Range
Transamerican; in Alberta specimens have been collected as far north as Calling Lake.
