Collection and habitat data.

This species is associated with deciduous and coniferous trees, usually occurring in debris around bases of trees, in tree holes, under bark, and in rotting wood of old fallen trees ( Smetana 1995). In New Brunswick, specimens were collected from compost (decaying vegetables) in a compost bin, from under bark of a spruce log, in a fleshy polypore mushroom on a beech log, and from Lindgren funnel traps. Adults were collected in May, June, July, August, and September.
