Collection and habitat data.

Little is known about the habitat associations of this species. Smetana (1995) speculated that it might live in burrows of mammals or, less likely, in bird nests. Two specimens from New Brunswick were found in moss at the base of a tree in an old-growth eastern white cedar swamp early in the season when some snow and ice were still present. This was possibly an overwintering site. Most specimens were captured in Lindgren funnel traps deployed in a variety of forest types (red pine, red oak, red spruce, mixed forest, old-growth northern hardwood forest). These traps mimic tree trunks ( Lindgren 1983), and it is possible that this species lives in microhabitats associated with standing trees. Adults were collected in April, May, June, and July.

Distribution in Canada and Alaska.

QC, NB ( Smetana 1995). This rare species was known from only a few localities in Quebec south to Massachusetts and west to Michigan, Kansas, and South Dakota ( Smetana 1995).
