Collection and habitat data. Habitat (outside of the study area). It occurs in many coniferous, mixed and hardwood/deciduous forest types in Canada. Adults commonly found in decaying mushrooms (polypore and gilled) and sometimes in fresh mushrooms. In NB, in an oak forest, rich Appalachian hardwood forest, northern hardwood forest, various mixed forests, red spruce forest, mature red spruce forest with red maple or yellow birch, black spruce forest, and eastern white cedar forests and swamps ; specimens in fresh and decaying gilled mushrooms of various species, rotting lobster mushrooms, and a coral mushroom on spruce log. Also captured in unbaited and carrion-baited pitfall traps and flight intercept traps in various coniferous (spruce-feathermoss, spruce-lichen forests), mixed (spruce/aspen, riparian), and deciduous forests in NF and LB including some from decaying mushrooms ; also from red maple, pine/willow, balsam fir/white birch forests, elsewhere. Collecting period. VI–X (most common in VIII and IX). Collecting method. Sifting litter and mushrooms, carrion-baited and unbaited pitfall traps, flight intercept traps, Lindgren funnel traps .
