Collection and Habitat data. The NH specimens were mainly captured in old-growth forests using flight intercept traps; also taken by pitfall and Malaise traps as well as found on the side of a water tower. Collected from October through the winter and spring to May. This forest species is found in Canada in association with decaying organic matter; in NB many were collected from among decaying vegetables (compost) either within or adjacent to a commercially available plastic compost bin near a mixed forest; others were found in moist leaves under sap flows from recently cut or wounded trees, decaying mushrooms, and moose dung in mixed forests ( Webster et al. 2009). In NS collected from dead pigs, a decaying gilled fungus, on a decaying Ganoderma shelf-fungus, in a pitfall trap, and in leaf litter at entrance of a cave (Majka et al. 2006). Reported from caves ( Klimaszewski and Peck 1986), and this species may be a cave specialist ( Klimaszewski and Pelletier 2004). However, occurrence in caves may be incidental as there are no apparent adaptations for cave life.
