Collection and habitat data.

In Europe, Quedius cinctus usually occurs in decaying organic material, usually near human settlements ( Smetana 1971a). In New Brunswick, specimens were similarly found in decaying organic material (decaying mushrooms, decaying corncobs and cornhusks, decaying leaves). One individual was found in wet moss along a cold, shaded brook. Adults were collected in April, July, September, and October.

Distribution in Canada and Alaska.

ON, NB ( Majka et al. 2009; Brunke and Marshall 2011). This adventive species was first reported from New Brunswick and Canada by Majka et al. (2009) from three specimens collected from a domestic pig carcass in Bouctouche (Kent Co.) in 2007. This species is probably well established in New Brunswick and likely occurs in the intervening areas between this province and Massachusetts (Framingham and Fall River, USA), where the species was first reported by Smetana (1971a) from North America.
