Collection and habitat data.

Klimaszewski et al. (2011) reported this species from coniferous, mixed, and deciduous forests in NF & LB. Specimens were captured in carrion-baited pitfall traps, unbaited pitfall traps, and flight intercept traps dur ing June, July, and August. Some adults were collected from decaying mushrooms in forests ( Klimaszewski et al. 2011). Most specimens from New Brunswick were collected from fresh and decaying gilled mushrooms. One individual was collected from a rotting lobster mushroom and another from a coral mushroom on a spruce log. This species was found in mixed forests, mature red spruce forests with red maple or birch, a black spruce forest, an eastern white cedar swamp, and a red oak forest. Adults from New Brunswick were collected during August, September (most specimens), and October.

Distribution in Canada and Alaska.

NB, NL, QC ( Klimaszewski et al. 2011). This species is probably more widely distributed in eastern Canada.
