Collection and habitat data.

This species was found in various forest types in New Brunswick. These included hardwood forests with sugar maple and American beech, an old red oak stand, mixed forests, an old eastern white cedar forest/swamp, a red spruce forest, and an old red pine forest. Most adults were captured in Lindgren funnel traps. Adults with specific habitat data were collected from polypore fungi and from polypore fungi on a dead, standing American beech and a dead, standing eastern hemlock ( Tsuga canadensis (L.) Carr.). One individual was collected at an ultraviolet light. This species and Orchesia castanea (Melsheimer) have an amazing jumping ability, and adults often jumped out of a 15 cm high sifting box, resulting in the loss of many specimens. Adults were collected during June, July, and August.
