Blethisa quadricollis Haldeman

Blethisa quadricollis occurs across Canada and northern USA, extending from Newfoundland to Alaska. It is recorded from 10 provinces and

two territories and from Alaska to Rhode Island (Fig. 2b) (Goulet 1983; Goulet and Smetana 1983; www.gbif.org/species/8216288). Our collection of the species presents the first record from Nunavut, confirming that it is found in all Canadian provinces and territories. The new records from Ontario’ s Far North fill in a gap, as it was previously reported from Moosonee, Ontario and Manitoba (Fig. 2b). Blethisa quadricollis inhabits acidic bogs and Sphagnum L. ( Sphagnaceae ) along the edges of pools.
