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).
