Collection and habitat data.

Little is known about the habitat associations of this species. Adults have been taken from leaf litter in Larix forests, in rotten Douglas-fir ( Pseudotsuga taxifolia Britton) and grand fir ( Abies grandis (Douglas ex. D. Don) Lindl.) logs, under board in a meadow, ex fungus, and in association with the ant Formica neorufibarbis Emery (probably accidentally) ( Smetana 1971a). The New Brunswick specimens were collected in Lindgren funnel traps deployed in an old (120- to 180-year-old trees) red pine forest, an old red oak forest, an old-growth northern hardwood forest, and an old-growth white spruce and balsam fir forest. Adults were collected during May, June, July, August, and September in New Brunswick and Quebec.

Distribution in Canada and Alaska.

NT, YT, BC, AB, MB, ON, QC, NB ( Smetana 1971a, 1990). The records from Quebec and New Brunswick represent significant range extensions east of the known distribution of this species reported by Smetana (1971a, 1990), indicating that this species is transcontinental in distribution in Canada.
