Natural history.

In NB, two specimens of Orus dentiger were sifted from decaying sea wrack on gravel sea beaches during May. Elsewhere, this species has been collected from March to November under stones, in soil samples, on lake shores, in sphagnum moss on the margin of a tamarack ( Larix laricina (Du Roi) Koch) marsh ( Blatchley 1910, Herman 1965), from clumps of moss and grass in a swamp, and under a log on a riverbank (CNC).
