Collection and Habitat data. The NH specimens were captured in leaf litter on marsh edge, under leaf litter around pond, from meadow sod, in old field, and from forest litter. Typically taken by sifting or by pitfall traps. Collected from April to October. In Canada most records from NB are from riparian habitats. Adults were sifted from flood debris and drift material along river margins, including many observed on surface of gravel near water’s edge on a gravel bar in river; some individuals were found under cobblestones; and one specimen taken from debris at entrance of Marmota burrow in a pasture (Webster et al. 2009). Elsewhere, it has been found in deciduous forests, a lucerne field, and a highbush blueberry field. In Europe it is common in natural habitats (Klimaszewski et al. 2018).
