Collection and habitat data.

Adults of this northern species are typically found by sifting Alnus and Salix spp. litter near margins of bogs, shallow lakes, and streams ( Campbell 1984a). They are also found in Carex hummocks (collected by treading hummocks into water) and in bird nests on ground ( Campbell 1984a). Most of the New Brunswick specimens were collected from a wet (emergent sedges) sedge marsh near a small lake by treading sedges and grasses near Myrica bushes into water. Two adults were found in leaf litter and moss under alders near a small brook in a Carex marsh, and one individual was found under a cobblestone on a shaded cobblestone bar in a brook. Adults were collected during May, June, and July.
