County records: Alger, Cheboygan, Chippewa, Dickinson, Gogebic, Huron, Isabella, Keweenaw, Leelanau, Luce, Marquette, Mecosta, Midland, Missaukee, Oscoda, Sanilac, Schoolcraft, Wayne, Wexford.

Notes. Biological information available from trap nests set out by Fye (1965) and Scott (1994, 1996) in Ontario and Michigan, respectively. There seem to be few recent records from the Northeastern United States, although the species is still routinely found further north and west.
