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).
