Collection and habitat data.

This species occurs in a wide variety of wetland habitats, usually associated with standing water such as wet meadows, marshes, swamps, forest seepages, and along pond and lake margins ( Smetana 1995). Some individuals were collected from muskrat nests. Adults were collected by sifting leaf litter, grass, and moss or by treading vegetation into water. In New Brunswick, this species was found in similar kinds of habitats. Adults were found in drift material near a seepage area along a river margin, among moist leaves on vernal pond margins in red maple and silver maple swamps, in a Carex hummock in a Carex flowage/marsh, in floating vegetation on a beaver pond margin, and in drift material on a lake margin. Adults were collected during May, June, and July.

Distribution in Canada and Alaska.
