This subspecies ranges from Newfoundland to southwestern Alaska, south to central British Columbia, southeastern Alberta, northern Minnesota, north-central Ohio (Purrington and Stanton 1996: 44), northern New York, and Maine [see Goulet and Baum 1982: Fig. 1]. The records from “California,” “Wyoming,” "South Dakota," “Iowa” (see Bousquet and Larochelle 1993: 87), and Missouri (Anonymous 2007) are likely based on mislabeled specimens or are in error.
