Collection and habitat data.

In Nova Scotia, this species was found in red spruce stands on Fomitopsis officinalis (Fr.) Bond. & Sing., in an old-growth hem lock ( Tsuga canadensis (L.) Carr.) forest, and in a mixed old-growth hemlock, black spruce ( Picea mariana (Mill.) B.S.P.), and balsam fir ( Abies balsamea (L.) Mill.) stand ( Majka and Langor 2011). This species has been reported from under bark of various hardwood and conifer species, and on fungi, such as Bjerkandera adusta (Fr.) Kar. and Phellinus gilvus (Schw.) Pat. ( Lawrence and Stephan 1975). In New Brunswick, Cerylon unicolor was collected from under bark of sugar maple, silver maple ( Acer saccharinum L.), red spruce, and a conifer stump. One individual was sifted from flood debris along a river margin, another was found in fleshy polypore fungi on a dead, standing American beech tree. This species was also captured in Lindgren funnel traps deployed in hardwood forests with sugar maple and American beech, mixed forests, a mature red oak forest, an old red pine forest, a mature red spruce forest, and an old eastern white cedar ( Thuja occidentalis L.) forest. Adults were captured during May, June, and July.
