Collection and habitat data.

In Newfoundland,this species has been captured in unbaited and carrion-baited pitfall traps in old balsam fir, spruce and balsam fir, birch and riparian forests and shrubby coastal barrens ( Klimaszewski et al. 2011). Gusarov (2004) reported this species from Abies , Betula , Picea , and Oxalis litter. The specimens from Nova Scotia were captured in a pan trap in a “closed” spruce woodland ( Majka and Klimaszewski 2010). Specimens from New Brunswick were sifted from moss and leaves under alders near a brook in an old-growth eastern white cedar swamp and from wet moss on the margin of a small, shaded, spring-fed brook in a white spruce and balsam fir forest. The adults were collected during May and August. Elsewhere, this species has been collected from June to October.
