Collection and habitat data.

Onichodon canadensis has been reared from decayed yellow birch ( Betula alleghaniensis Britt.), collected at black lights, and found on red spruce and Fagus sp. ( Muona 2000). This species was found in various forest types in New Brunswick. These included a mature hardwood forest with beech, an old red oak and maple forest, an old red oak forest, an old silver maple swamp, an old mixed forest with red and white spruce ( Picea glauca (Moench) Voss), red and white pine, balsam fir, eastern white cedar, red maple, and Populus sp., a red spruce forest with red maple and balsam fir, and an old-growth eastern white cedar forest. Most adults were captured in Lindgren funnel traps. One individual was collected at black-light trap, another in a window trap. Adults were captured during July and August.

Distribution in Canada and Alaska.

ON, QC, NB, PE, NS ( Bousquet 1991; Majka 2007). Bousquet (1991) reported this species for New Brunswick, but no supporting voucher specimen was found in the CNC or other collections examined by Majka (2007). However, a specimen in the NBM collected by W. McIntosh in Saint John on 6 August 1900 was located, establishing this species as a member of the New Brunswick fauna ( Majka 2007). The above records provide the first recent records of this species from the province.
