Collection and habitat data.

In New Brunswick, this species was collected from a variety of wetland types. These include a tamarack bog, a black spruce bog, an old eastern white cedar swamp, Carex marshes, and an old beaver ( Castor canadensis Kuhl) flowage with grasses. Adults occurred in sphagnum hummocks in bogs, in moss and litter at bases of trees, in litter and sphagnum in marshes, and in grass litter near a brook in an old beaver flowage. One individual was captured in a Lindgren funnel trap deployed in an old red oak forest. Chandler (1997) reports specimens being taken from sphagnum moss, swamp debris, tree holes, and from a mixture of birch/alder litter on the margin of a freshwater marsh. Adults were collected during April, May, and June.
