Collection and habitat data.

Brunke et al. (2011) reported that Staphylinus ornaticauda was restricted to wetlands, such as bogs and fens, with an abundance of sphagnum moss. In New Brunswick, this species appears to be associated with eastern white cedar swamps and fens and red maple swamps on calcareous soils. Adults were collected in eastern white cedar swamps, an eastern white cedar, red maple, and black ash ( Fraxinus nigra Marsh.) swamp, and in a red maple swamp near an eastern white cedar swamp. Adults occurred in litter at the base of cedars, and in moist litter and moss near small vernal pools with Carex . Adults were collected by sifting litter. This species was collected in April, May, and June. This species is flightless ( Brunke et al. 2011). Due to the limited dispersal capabilities, restricted habitat requirements, and apparent rarity, Brunke et al. (2011) suggested that this species should be studied as a potential species at risk.

Distribution in Canada and Alaska.
