Collection and habitat data.

Bibloporus bicanalis was reported from white pine litter ( Chandler 1997), and Klimaszewski et al. (2007) indicated that the largest numbers have been taken using intercept traps in old-growth forests, particularly where old conifers are present. In New Brunswick, adults were captured Lindgren funnel traps deployed in a mature hardwood forest with sugar maple, American beech, and white ash ( Fraxinus americana L.), an old red oak forest, an old mixed forest, an old-growth northern hardwood forest with sugar maple and yellow birch, a mature mixed forest, an old red pine forest, an old eastern white cedar forest/swamp, a 110-year-old red spruce forest, and an old-growth white spruce and balsam fir forest (boreal forest). This species was most frequently captured in hardwood forests. Adults were captured during April, May, June, and September.
