This species was collected from nest contents of barred owls (Strix varia Barton) and from a gilled mushroom on a tree. Adults were also collected from Lindgren funnel traps deployed in hardwood forests with sugar maple (Acer saccharum Marsh.) and American beech (Fagus grandifolia Ehrh.), an old red oak (Quercus rubra L.) forest, an old-growth northern hardwood forest, a 110-year-old red spruce (Picea rubens Sarg.) forest, and an old red pine (Pinus resinosa Ait.) forest. This species is probably associated with decaying organic materials associated with standing trees. Adults were collected during June, July, August, and September.

In New Brunswick, adults were collected from under tight-fitting bark of a standing dead birch (Betula sp.) and a standing dead balsam fir (Abies balsamea (L.)

Acidota quadrata occurs in arctic and alpine tundra areas south into the boreal forest (Campbell 1982). Relict populations from New Hampshire and Maine occur in alpine areas. Adults have been found in leaf litter, in wet moss, and under rocks near streams, in flood debris near rivers, inside a beaver lodge, and in wet moss and clumps of dead grass in alpine tundra (Campbell 1982). The specimen from New Brunswick was sifted from moss and leaf litter, near a brook in an old-growth eastern white cedar (Thuja occidentalis L.) swamp during May.

Adults of this northern species are typically found by sifting Alnus and Salix spp. litter near margins of bogs, shallow lakes, and streams (Campbell 1984a). They are also found in Carex hummocks (collected by treading hummocks into water) and in bird nests on ground (Campbell 1984a). Most of the New Brunswick specimens were collected from a wet (emergent sedges) sedge marsh near a small lake by treading sedges and grasses near Myrica bushes into water. Two adults were found in leaf litter and moss under alders near a small brook in a Carex marsh, and one individual was found under a cobblestone on a shaded cobblestone bar in a brook. Adults were collected during May, June, and July.

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.

This Holarctic species has been collected from moss and Carex hummocks, along lake, stream, and bog margins, from floating debris on streams, and in moist Salix and Alnus spp. litter (Campbell 1983b). Most specimens from New Brunswick were collected from moss, sphagnum, and leaf litter in and near eastern white cedar swamps and in Carex marshes. Adults were collected by sifting moss and litter or treading Carex hummocks and vegetation into water. This species was collected during April, May, June, July, and August.

This species is rarely collected, in part because it is primarily active in the late fall and early winter (Campbell 1984b). Adults have been found crawling on snow on a warm day in November and by sifting moss and plant debris in October and November (Campbell 1984b). The New Brunswick specimens were found floating on water on the surface of frozen puddles along a forest trail after a heavy rain the previous night that had melted a 10 cm deep snow cover. Presumably the adults were washed into the puddles by the heavy rain. The adults were collected in late November.

This is a fungicolous species occurring in various species of mushrooms (including Russula sp.), typically those growing on rotting wood (Smetana 1996). Smetana (1996) reported that numerous specimens were captured in flight intercept traps. All records from Smetana (1996) were from September and October. In New Brunswick, adults were collected during September on Pholiota sp. at the base of a dead black cherry (Prunus serotina Ehrh.), a dead Populus sp., and on a log. One individual was collected from a gilled mushroom on the forest floor. Adults were found in a mature mixed forest, an eastern white cedar swamp, and in an old-growth northern hardwood forest.

Webster, old growth mixed forest, shaded brook, in gravel on gravel bar (3 ♂, 4 ♀, NBM, RWC).

In New Brunswick, Coryphium nigrum was found on margins of heavily shaded brooks, usually on a gravel, sand, and clay mix. One teneral individual was collected from saturated moss on a rock in a brook. Adults were collected either by turning pebbles and gravel or more easily by lightly splashing the brook margin. Adults were collected after they moved to the tops of the pebbles, but were often difficult to see due to the low light levels of the habitat. Nothing was previously known about the biology of this species other than that adults were collected in late March through May and in September (Campbell 1978). Campbell (1978) suggested that adults were probably most active during spring or even late winter like other members of the tribe. In New Brunswick, adults were collected from mid to late June and early July, and were common at this time.

Habrocerus capillaricornis has been reported from forested areas under bark, in litter, in fungi (Assing and Wunderle 1995) and from compost (Brunke et al. 2011). In New Brunswick, this adventive species was common among decaying leaves in a pile of leaves made the previous year. Other adults were observed among a pile of decaying corncobs and cornhusks nearby and from compost (Webster, unpublished data). Adults were also found under bark of spruce in a woodpile, in decaying fungi, in the wall of a beaver lodge and at a black-light trap. Adults were collected during April, May, July, and August.

New Brunswick, Restigouche Co., Jacquet River Gorge P.N.A., 47.8160°N, 66.0083°W, 14.VIII.2010, R. P. Webster, old eastern white cedar forest, in decaying mushrooms (2 ♂, NBM, RWC). York Co., Canterbury, near Browns Mountain Fen, 45.8954°N, 67.6307°W, 7.IX.2007, R. P. Webster, mixed forest along forest trail, in decaying gilled mushrooms (1 ♂, 2 ♀, RWC).

Assing and Wunderle (1995) reported that this species was most often collected from well-decayed fungi, but was also found in moose (Alces alces L.) and grouse (Bonasa umbellus L.) dung and leaf litter. Paquin and Dupérré (2002) captured large numbers of this species in pitfall traps deployed in the southern boreal forest of Quebec. The specimens from New Brunswick were found in decaying gilled mushrooms in a mature mixed forest and an old eastern white cedar forest. Adults were collected during August and September.

New Brunswick, Charlotte Co., near Little Pocologan River, 45.1731°N, 66.6141°W, 7.V.2007, R. P. Webster, clear-cut, under bark of large Pinus strobus (white pine) log (1, RWC). York Co., 15 km W of Tracy off Rt. 645, 45.6837°N, 66.8809°W, 16.VI.2007, R. P. Webster, small clear-cut, under bark of red pine stump (1, RWC); same locality, collector but 45.6848°N, 66.8821°W, 27.VIII.2008, R. P. Webster, old red pine forest, under bark of large standing dead white pine (4, RWC).

Brunke et al. (2011) noted that almost nothing was known about this rarely collected species but mentioned that it shared morphological features with other Staphylinidae living in subcortical habitats. Most adults ofHabrocerus magnus from New Brunswick were found under somewhat loose bark of white pine (Pinus strobus L.) (large logs and a large, dead, standing tree). One individual was collected from under bark of a large red pine stump. These data suggest that this species lives under bark of large dead conifers. Adults were collected during May, June, and August.
