Collection and habitat data.

Specimens have been collected from moss along a stream margin, sweeping vegetation along a stream margin, from a Berlese sample from a decayed stump, at light and from emergent Carex in an alder swamp (Campbell 1983b). In New Brunswick, adults were common among emergent Carex in an open section of a tamarack ( Larix laricina (Du Roi) Koch) bog near a small, slow-flowing stream. Adults were collected by treading vegetation into water. One adult was also collected from litter (mostly Carex sp.) on muddy soil on the inland margin of a salt marsh. All adults were collected during May.

Distribution in Canada and Alaska.

ON, QC, NB (Campbell 1983b). This species occurs in the eastern third of the United States northward to Quebec and Ontario (Campbell 1983b).
