Collection and Habitat data. In NH captured in alder and grass leaf litter in a boreal forest, and above tree line in dwarf Salix , Vaccinium , and leatherleaf litter. Collected only in September. In Canada found in various wetland habitats: Carex marsh in emergent vegetation (treading, very common), splashing exposed bedrock next to waterfalls among cobblestones, gravel, and sand, on gravel bar near outflow of brook into a river, in hardwood forest in moist leaves on vernal pond margin, upper margin of sea beach in drift material (mostly grass litter), and two individuals were collected with an aerial net in late afternoon when snow was still present in shaded areas of the woods ( Webster et al. 2009). In QC found in leaf litter next to stream; in Salix litter at two localities in the YT; and in NL taken by a flight intercept trap in a mixed forest ( Klimaszewski et al. 2018).
