Collection and habitat data.

Smetana (1995) reported that this species typically occured under bark of both deciduous and coniferous species and was often associated with old trees. Adults occur in debris under bark, in rotting wood, and in wood and debris around the bases of dead standing trees. This species has also been found in rotting mushrooms and forest floor litter and has been taken in flight intercept traps ( Smetana 1995). In New Brunswick, this species was found in similar habitats, including under bark of American beech, red maple, red oak, red spruce, and from the nest contents of a barred owl. Adults were also collected in Lindgren funnel traps and in flight during evening flights. Adults were captured during April, May, June, and August.

Distribution in Canada and Alaska.
