Collection and habitat data.

Campbell (1991) reported this species from a variety of habitats, including forest leaf litter, fungi on an old tree stump, among grass roots, damp moss near a pond, under a log on a lakeshore, and from Microtus pennsylvanicus (Ord) nests. In New Brunswick, specimens were found in a various microhabitats including leaf litter and moss near brooks, margins of vernal ponds and a river, leaf litter at bases of trees, and among decaying corncobs and cornhusks. This species was found in a Carex marsh, mature hardwood forests, silver maple swamps, mixed forests, and river and brook margins. Adults were collected during April, May, June, and September and were active early in the spring on bare patches around bases of trees when over 30 cm of snow was still on the ground.
