Collection and habitat data.

This species lives under bark of logs and trees ( Deyrup and Gara 1979; Newton et al. 2000). In New Brunswick, adults were collected from under tight-fitting bark of a standing dead birch ( Betula sp.) and a standing dead balsam fir ( Abies balsamea (L.) Mill.), and from a pile of plywood disks. Adults were captured in Lindgren funnel traps at several sites. Adults were collected during May, June, July, and August.
