Collection and habitat data.
In Europe, this species is typically found in synanthropic situations in decaying organic materials such as compost ( Smetana 1971a). It has also been reported from mammal burrows, tree holes, and caves in natural settings. In New Brunswick, adults were collected from under bark of a fungus-covered, dead, standing basswood, among moist wood chips and decaying plant material, and from Lindgren funnel traps deployed in a hardwood forest and an old-growth white spruce and balsam fir forest. Adults were captured in June, July, September, and October.
Distribution in Canada and Alaska.
