Collection and Habitat data. In NH captured in leaf litter on spring edges, and by flight intercept traps in mixed and coniferous forests. Collected from May to September in northern NH. In AK found on arctic tundra and in clear-cuts ( Klimaszewski et al. 2021). In western Canada recorded from a variety of coniferous forests, and a subalpine meadow at 3000 feet in moss seepage on a slope ( Klimaszewski and Winchester 2002a, Klimaszewski et al. 2021). In NB found in moss and leaves under alders near a brook in an eastern white-cedar swamp, from under cobblestones and gravel in sand on a partially shaded cobblestone bar near outflow of brook into a river, and in moss along a shaded spring-fed brook in a boreal forest area ( Klimaszewski et al. 2021).
