Collection and habitat data
In New Brunswick, adults of this species were collected in a mature hardwood forest with American beech, sugar maple, and ash, mixed forests, and an old red oak forest. Most individuals were collected from partially dried Pleurotus sp. on dead standing Populus sp. and on a slightly dried Climacodon septentrionale (Fr.) Kar. on a dead standing sugar maple. A few adults were also captured in Lindgren funnel traps and at an ultraviolet light. Skelley et al. (1991)[1] reported that larvae of this species feed in a variety of hard and soft basidiomycete bracket fungi, including Pleurotus sp. In New Brunswick, adults were collected during June and September.
