Collection and Habitat data. In NH adults were captured in maple litter along a stream in a forest, leaf litter around pool edge, beach wrack, and by FIT and window traps. Collected from May to August with most collections taken in May. In Canada specimens were taken among cobblestones on a lakeshore and from a Lindgren funnel trap in the canopy of Populus tremuloides in a hardwood forest; one individual was found in bison dung in BC, and another taken by a window trap set in a 10-year-old regenerating white spruce stand in AB ( Webster et al. 2016, Klimaszewski et al. 2018).
