Collection and habitat data. Little is known about the habitat requirements of this rare species. Campbell (1982) reported that adults have been taken on rotting gilled mushrooms. Most of the specimens from New Brunswick were collected from the fleshy polypore fungus, Bjerkandera adusta (Willd.) P. Karsten growing on a dead, standing American beech tree and a beech log. One individual was found in a mass of Pholiota sp. mushrooms at the base of a dead, standing Populus sp. Another individual was captured in a Lindgren funnel trap. Adults were found in mature hardwood and adjacent mixed forests, and in an old-growth white spruce and balsam fir forest. This species was collected during September in New Brunswick. Distribution in Canada and Alaska. AK, BC, AB, ON, PQ, NB, NS ( Campbell 1982 ; Campbell and Davies 1991 ). This northern species has a very broad distribution from Alaska to Nova Scotia, but with large distributional gaps between known localities ( Campbell 1982 ).
