Specimens of this species from New Brunswick were collected from a decaying fleshy polypore mushroom on a standing, dead spruce in a mature red spruce forest, from a decaying Climacodon septentrionale (Fr.) P. Karst. on a dead, standing yellow birch in a recent clearcut (boreal forest area), and from a (fresh) Climacodon septentrionale (Fr.) P. Karst. on a living sugar maple in an old-growth northern hardwood forest. Four individuals were collected in company with Lordithon niger (Gravenhorst) from a decaying fleshy polypore fungus on a standing, dead Populus sp. in a hardwood forest (sugar maple and American beech) in Saint-Raphaël (15.VII.2006), Quebec (Webster, unpublished). One specimen from Tennessee (USA) was sifted from leaf litter. Little was previously known about the habitat and biology of this rare species. Campbell (1973) suggested that this species lived in some restricted habitat, such as mammal burrows. The habitat data above suggest that this species may be associated with decaying fleshy polypore or polypore-like fungi on standing dead and living trees. Adults were collected during July and August.

Campbell (1991) reported this species from river banks, flood debris on rivers, under logs, and decaying vegetation. Most New Brunswick specimens were found in litter in crotches of silver maples with multiple trunks in an old silver maple swamp (floodplain forest) early in April. This habitat was probably an overwintering site for this species. Many other staphylinid adults of various species were found in the debris in these tree crotches. Other individuals were sifted from leaf litter at the bases of large silver maples. Adults were collected during April and May.

This is a hygrophilous species in both Europe and North America and is usually found in marshes and bogs in moss (especially sphagnum) and debris (Campbell 1991). In New Brunswick, this species was found in various wetland habitats, including a forested black spruce (Picea mariana (Mill.) B.S.P.) bog, an eastern white cedar swamp, sedge (Carex) fens and marshes, freshwater marshes, stream margins, the margin of a vernal pond, and in an abandoned North American beaver Castor canadensis Kuhl) lodge occupied by muskrats (Ondatra zibethicus L.). Adults occurred in moist leaves, sphagnum, litter, and moss, in Carex hummocks, and in debris in the roof of a beaver lodge. In New Brunswick, this species was collected during March, April, May, and June.

ON, QC, NB (Campbell 1991). Campbell (1991) considered the distribution and habitat of this species in the Nearctic region unusual for a Holarctic species because of the specialized habitat preferences (found in sphagnum and debris in marshes and bogs) and pattern of distribution (restricted to Ottawa Valley of Ontario and Quebec). He suggested that the species may have been overlooked by most collectors and may actually have a broader distribution in North America than the records indicate. Klimaszewski et al. (2010) considered Tachyporus transversalis Gravenhorst as an adventive Palaearctic species.

Campbell (1991) reported that this species was often found in drier habitats than other members of the Pictum group of species. Adults were reported from various kinds of forest litter in pine, hardwood, and mixed pine and hardwood forests as well as cypress forests (Campbell 1991). In New Brunswick, this species was most often found in and near wetland habitats, such as calcareous fens, Carex marshes, tamarack (Larix laricina (Du Roi) Koch) bogs, alder swamps, and red maple swamps. One adult was found near a stream in a mature hardwood forest. Adults occurred in moss and sphagnum hummocks, moss, leaf and grass litter at bases of trees, and Carex hummocks. Adults were collected during April, May, June, and September.

Campbell (1991) reported this species from various of wetland habitats as well as forests. Adults were taken from flood debris along rivers, margins of beaver ponds, beaver lodges, muskrat nests, mallard (Anas platyrhynchos L.) nests, moss near seepage areas, leaf litter along margins of marshes, streams, and bogs, and various kinds of grass and leaf litter from conifer and deciduous forests (Campbell 1991). Recent studies in Alberta (mid-boreal ecoregion) by Buddle et al. (2006) indicated that this species was associated with old (>70-year-old) fire-origin, mixed wood forest stands. Later, Pohl et al. (2007) reported that this species was also associated with regenerating mixed wood stands in the western foothills of Alberta. The specimens from New Brunswick were collected in moldy conifer duff and fleshy gilled mushrooms in a small balsam fir (Abies balsamea (L.) Mill.) (regenerating) stand adjacent to a hardwood forest. Campbell (1991) reported most specimens of this species were taken in June to September. The specimens from New Brunswick were collected during May and September.

Little is known about the habitat requirements of this rare species. Campbell (1982) reported that adults have been taken on rotting gilled mushrooms. Most of the specimens from New Brunswick were collected from the fleshy polypore fungus, Bjerkandera adusta (Willd.) P. Karsten growing on a dead, standing American beech tree and a beech log. One individual was found in a mass of Pholiota sp. mushrooms at the base of a dead, standing Populus sp. Another individual was captured in a Lindgren funnel trap. Adults were found in mature hardwood and adjacent mixed forests, and in an old-growth white spruce and balsam fir forest. This species was collected during September in New Brunswick.

Little was previously known about the habitat associations of this rare species (Campbell 1982). In New Brunswick, adults of Lordithon quaesitor were most frequently found on Bjerkandera adusta (Willd.) P. Karsten (a fleshy polypore fungus) on the side of beech logs and standing dead beech trees in mature hardwood forests. This species was also found in Pleurotus sp., among a group of Polyporus varius Fr. on a large sugar maple log and on a dead standing American beech in an old-growth hardwood forest with sugar maple and yellow birch, in polypore fungi on sides of logs, in Pleurotus sp. on a dead standing balsam poplar (Populus balsamifera L.) tree, and in a gilled mushroom on the forest floor of an old-growth northern hardwood forest with sugar maple and yellow birch. One adult was collected in a Lindgren funnel trap. Some adults were collected in a mature red spruce forest, a mixed forest, and an alder swamp adjacent to a mixed forest. Lordithon quaesitor was sometimes found together with Lordithon niger, Lordithon axillaris, and Lordithon longiceps and probably has a similar biology to those species. Adults were collected during May, June, July, August, and September.

New Brunswick, Carleton Co., Hovey Hill P.N.A., 46.1115°N, 67.7770°W, 19.VIII.2004, R. P.

Webster, hardwood forest, in Laetiporus sulphureus (1, RWC).

Little was previously known about the habitat associations of this rare species. One specimen from Quebec was collected from large gilled mushrooms on the side of a log (Campbell 1982). Four specimens of this species were collected from Pleurotus sp. mushrooms on the side of Populus logs in a hardwood forest in Saint-Raphaël (15.VII.2006), Quebec (Webster, unpublished). Most specimens from New Brunswick were collected from Pleurotus sp. mushrooms on standing dead Populus sp. trees or on the side of logs in mature hardwood forests with sugar maple and beech. Some adults were also collected from a large orange-gilled mushroom on the side of a log. One individual was collected from inside a Laetiporus sulphureus (Fr.) Murr. (Polyporaceae). These data suggest that this species may be specialized on Pleurotus sp. and other large gilled mushrooms that grow on standing dead trees or logs. Campbell (1982) suggested that this species, like Lordithon niger and the European Lordithon bicolor (Gravenhorst), may be associated with old-growth hardwood forests. Adults of Lordithon axillaris were collected during June, July, and August in New Brunswick.

Nothing was previously known about the habitat associations of this rare species (Campbell 1982). The New Brunswick specimens were collected from Bjerkandera adusta (Willd.) P. Karsten and Porodaedalea sp. (both are fleshy polypore fungi) on a beech log, or on dead, standing beech trees in a mature to old-growth and predominantly hardwood forest. One individual was captured in a Lindgren funnel trap in a mature to old red oak forest. Several specimens of this species were found in company with Tachinus schwarzi in a decaying fleshy polypore fungus on a standing, dead Populus sp. in a hardwood forest in Saint-Raphaël (15.VII.2006), Quebec (Webster, unpublished). Adults from New Brunswick were collected during June, August, and September. The habitat data above suggest that this species might be specialized on fleshy polypore fungi and related species that grow on dead standing trees or logs. Campbell (1982) noted that this species appeared to be becoming increasingly rare and suggested that it might be associated with old-growth hardwood forests, which are disappearing from most of eastern North America. However, more sampling should be done in forests of various ages to establish if this species is indeed an old–growth associate.

Adults of Mycetoporus rugosus have been collected from a wide variety of moist (often deep and moldy) litter and moss, including both deciduous and conifer litter of various species in forested habitats, as well as lake, stream, and river margins (Campbell 1991). New Brunswick specimens were collected from similar habitats, most frequently from moss and litter near brooks in old-growth eastern white cedar swamps. Adults were also collected from drift material and oak leaf litter along a lakeshore and from sphagnum in a black spruce forest. Adults from New Brunswick were collected during May and June.
