Collection and habitat data.

This species typically occurs under bark of dead conifers ( Newton et al. 2000), the same habitat from which most New Brunswick specimens were collected. Adults were collected from under bark of large fallen spruce and under bark on the underside of a large red pine log. Two adults were captured in Lindgren funnel traps in an old-growth red pine forest. Adults were collected during May, June, July, and August.
