scientific name    Carabus chamissonis    

habitat
Found primarily in open, dry country, particularly the tundra.

seasonality
Adults have been collected in May to September.

identification
This species is in the subgenus Oreocarabus. A rather variable species, but common features are: Black, without any trace of metallic lustre, elytra often rufinistic. The raised margin of prothorax is better defined inwards than in nemoralis. The elytral sculpture is based on seven faint ridges on each interval between the rows of foveae but the ridges are irregular, often so obscure and confluent that the impression is of punctures arranged into winding rows. Length 12.4 to 16.5 mm.

life history
Presence of immature adults in August suggests this species overwinters in the adult stage.

conservation
Common.

diet info
Both larvae and adults are predatory.

range
This species is found in Alaska and northeastern United States and ranges across most of Canada. In Alberta this species is relatively common throughout, except the very dry south-east regions.
