Collection and habitat data.

One of the Nova Scotia specimens was collected by treading wet Sphagnum ( Smetana 1973), otherwise little is known about the habitat associations of this species ( Smetana 1971a). Specimens from New Brunswick were collected in red oak and red maple forests, a red spruce and red maple forest, an old sugar maple and American beech forest, and regenerating mixed forests. Adults were collected from gilled mushrooms, a decayed fleshy polypore fungus on a log, from a rotten fungus-covered log, baited with decaying mushrooms, sifted from sphagnum and leaf litter at bottom of old tire depression, and swept from foliage in a regenerating forest. Adults were also captured in pitfall traps in large numbers ( Klimaszewski et al. 2005). This species is probably associated with decaying organic matter, such as decaying mushrooms. Adults were captured during July, August, September, and October.

Distribution in Canada and Alaska.

ON, QC, NB, NS ( Smetana 1971a, 1973; Klimaszewski et al. 2005). This species was first reported from New Brunswick by Klimaszewski et al. (2005) from specimens collected in pitfall traps at the Acadia Research Forest (Sunbury Co.)
