Collection and habitat data.

Campbell (1976) reported that most specimens of this species were collected from under bark. Others were found in mushrooms, Polyporus betulinus (Bull.) Fr., on dead logs, dead beech ( Fagus grandifolia Ehrh.), and tree trunks and in tree holes. In New Brunswick, specimens were found on fleshy polypore fungi on a beech log, in Piptoporus betulinus (Bull.) P. Karst. (birch polypore), on Polyporus varius Fr., and in a well-rotted log. This species was commonly collected in Lindgren funnel traps in various forest types; mature hardwood forests with sugar maple ( Acer saccharum Marsh.) and beech, old red oak ( Quercus rubra L.) forest, old-growth hardwood forest with sugar maple and yellow birch ( Betula alleghaniensis Britt.), 110-year-old red spruce ( Picea rubens Sarg.) forest with red maple ( Acer rubrum L.), old red pine ( Pinus resinosa Ait.) forest, and an old mixed forest. Adults were collected during April, May, June, July, August, and September.
