Collection and habitat data.

Smetana (1976) reported this species from moss, mushrooms, and deciduous leaf litter (birch and poplar stands) near streams. In the Alberta foothills forests, Quedius labradorensis was considered to be an open-ground specialist after forest harvesting and only extended a short distance into adjacent uncut forests ( Pohl et al. (2007). Numbers of this species also increased after harvesting. In New Brunswick, most adults were found in old-growth eastern white cedar swamps in moss usually near small streams. One adult was found under white-tailed deer ( Odocoileus virginianus (Zimmerman)) dung, and another was collected at a mercury-vapor light. Adults were collected during April and May.

Distribution in Canada and Alaska.

AK, BC, NT, AB, MB, ON, QC, NB, NF ( Smetana 1971a, 1973, 1976, 1978). Majka et al. (2011) listed this species as occurring in New Brunswick without any supporting references or data. Here, we provide the first documented records from New Brunswick.
