Collection and Habitat data. The ME specimens were captured in April and November by a flight intercept trap; the MA specimens were captured by a funnel trap with a SPB Lure, and another specimen was taken from a Betula sp. In Canada this species was found in hardwood forests under bark of American beech ( Fagus grandifolia Ehrh. ) logs (common), under bark of sugar maple (common), and in fleshy polypore (bracket) fungi on a dead standing beech tree, and under bark of unidentified trees ( Webster et al. 2009). These data suggest that this species is associated with subcortical habitats and other habitats associated with trees ( Klimaszewski et al. 2018). Elsewhere, this species was captured in various kinds of traps in sugar maple, red spruce, red spruce/hemlock ( Tsuga canadensis (L.) Carriére), and black spruce ( Picea mariana (Mill.) B.S.P) forests, with some being young, mature, and old-growth, ( Klimaszewski et al. 2018).
