Collection and habitat data.

In New Brunswick, Homaeotarsus cinctus  was found in Carex  marshes, open calcareous cedar fens, a forested black spruce ( Picea mariana  (Mill.) B.S.P.) bog, and in a kettle hole bog with a floating bog mat. Adults were found in wet to saturated sphagnum with scattered sedges often in a floating mat, among emergent sedges and grasses, and in sphagnum hummocks. Adults were collected by treading these microhabitats. Some adults were sifted from sphagnum and leaf litter at bases of trees on a Carex  marsh margin. This species was collected during April, May, June, July, and August.
