|scientific name Carabus granulatus |
In open country or light deciduous woods, usually near water, often on cultivated ground.
The only Alberta specimen was collected in September.
This species, in the subgenus Carabus, is a European introduction. Black, upper surface and prosternum usually with rather dull brassy, sometimes greenish lustre. More slender than C. meander, with longer antennae and legs. The elytral sculpture is almost identical, except that a sutural ridge, inside the first row of tubercles, is at least suggested basally. Prothorax more pronouncedly square, with more broadly flattened sides. The elytral margin is not serrate behind the shoulders. Length 16 to 24 mm.
Known to overwinter in the adult stage.
Introduced; not common.
Both larvae and adults are predatory.
This species is found in the Massachusetts and Washington (state) in the United States and has a disjunct distribution in Canada. In Alberta there is a single record from Edmonton.

Interesting. I think this is the beetle we just found jaunting around on our upstairs hall carpet. We are near Martensville, Saskatchewan, just north of Saskatoon, on an acreage. June 10, 2015
