Collection and habitat data.

Penthe obliquata was found in mature hardwood forests with American beech and sugar maple, an old-growth northern hardwood forest, a floodplain forest with black ash ( Fraxinus nigra Marsh.), butternut, and red maple, an old red oak forest, a red oak and red maple stand, a silver maple swamp, a mature (110-year-old) red spruce stand, an old (180-year-old) red pine forest, an old eastern white cedar forest, and in mixed forests. Many adults were captured in Lindgren funnel traps deployed in the above forest types. Adults with specific collection data were collected from polypore fungi (bracket fungi) on standing dead American beech trees and poplar logs, in fleshy polypore fungi on a dead, standing red oak and on a stump, from a woody polypore on a dead, standing balsam fir, from Polyporus varius Fr. on a dead, standing sugar maple, and from under bark of a spruce log. Majka and Pollock (2006) reported this species from under bark of a variety of conifer species in Nova Scotia. They also reported adults from belted polypore, Fomitopsis pinicola (Fr.) Kar., on conifers. Adults from New Brunswick were captured during May, June, July, August, and September,
