Collection and habitat data
In New Brunswick, adults of this species were captured in Lindgren funnel traps in a hardwood forest with sugar maple (Acer saccharum Marsh.), American beech (Fagus grandifolia Ehrh.), white ash (Fraxinus americana L.), and small areas of eastern hemlock (Tsuga canadensis (L.) Carr.) and eastern white cedar (Thuja occidentalis L.), an old mixed forest with red spruce, white spruce (Picea glauca (Moench) Voss), red pine (Pinus resinosa Ait.), white pine (Pinus strobus L.), balsam fir (Abies balsamea (L.) Mill., eastern white cedar, red maple (Acer rubrum L.), and Populus sp., an old red pine forest, and an old-growth white spruce and balsam fir forest. White (1982) reported this adventive Palaearctic species from under bark of pine, hemlock, and hickory (Carya sp.). Adults were captured during May and June in New Brunswick.
