Collection and habitat data.

Microhagus subsinuatus was reared from a moist, decayed Fagus grandifolia log ( Knull 1946) and swept from milkweed ( Blatchley 1910). This species was found in various forest types in New Brunswick. These included a mature hardwood forest with American beech, sugar maple, and ash, an old silver maple forest with green ash, a red spruce forest with red maple and balsam fir, an old-growth northern hardwood forest, an old-growth white spruce and balsam fir forest, and an old-growth eastern white cedar forest. Most adults were captured in Lindgren funnel traps. One individual was swept from foliage in a mature hardwood forest. Adults were collected during June, July, and August.
