Collection and habitat data.

In New Brunswick, adults were usually found in moss, leaf, and grass litter near various kinds of wet habitats. These included Carex marshes, shaded brook margins, a vernal pond in a mature red spruce and eastern white cedar forest, and on hummocks in an old-growth eastern white cedar swamp. Elsewhere, this species has been found in similar habitats, including a series collected from a beaver lodge ( Smetana 1982). Adults were collected during April, May, and June.
