Collection and habitat data.

Nearly all Tetartopeus  spp. have been collected in association with wetland habitats, usually in accumulations of damp leaf litter, moss, and other debris along streams, bogs, marshes, swamps, and ponds ( Watrous 1980). Watrous (1980) noted that Tetartopeus capitosus  (as Latrobium (Tetartopeus) punctulatum  LeConte) occurred mostly in the boreal forest region but gave no specific habitat data for this species. In New Brunswick, adults of this species were found in silver maple swamps (floodplain forests), a red oak and silver maple forest, along a lake margin, and in a tamarack ( Larix laricina  (Du Roi) K. Koch) bog. Adults were found in leaf litter near vernal ponds, under drift material on a lake margin, and by treading Carex  in a tamarack bog, and one individual was captured at an ultraviolet light.
