Collection and habitat data.

Most adults from New Brunswick were collected from well-decayed gilled and boletus mushrooms that had been placed in an opening in a 20-year-old regenerating mixed forest. One individual was caught in a Lindgren funnel trap deployed in an old red pine forest. Adults were collected during June, July, and August. Little was previously known about the biology of this species (Bousquet and Laplante 2006).
