Collection and habitat data.

Assing and Wunderle (1995) reported that this species was most often collected from well-decayed fungi, but was also found in moose ( Alces alces L.) and grouse ( Bonasa umbellus L.) dung and leaf litter. Paquin and Dupérré (2002) captured large numbers of this species in pitfall traps deployed in the southern boreal forest of Quebec. The specimens from New Brunswick were found in decaying gilled mushrooms in a mature mixed forest and an old eastern white cedar forest. Adults were collected during August and September.
