Two individuals were collected from under cobblestones along a lakeshore in August, another was captured in a Lindgren trap in the canopy of a trembling aspen in a hardwood forest in June. In Alberta, one female was collected with a window trap and in British Columbia, specimens were found in bison dung ( Klimaszewski et al. 2015a).
