Native to the Nearctic region. Widespread in the eastern United States ( Gustafson and Miller 2015 ). Canadian records. Ontario: Charleston Lake Provincial Park, 22-Jun-2015 (2 exx, CBG); Charleston Lake Provincial Park, 25-Jun-2015 (2 exx, CBG). Diagnostic information. See Gustafson and Miller (2015) . Bionomic notes. Recorded from a variety of lotic and lentic freshwater habitats ( Gustafson and Miller 2015 ). The Canadian adult specimens were hand-collected at a boat launch site on the shore of Charleston Lake, and two larvae matched to the adults by barcode sequences were collected with a dip net at a different site in the same lake.
