Collection and habitat data.

This species appears to prefer decaying organic substances and has been found on carrion, under human feces ( Smetana 1971a), and in fleshy fungi ( Blatchley 1910). In New Brunswick, most specimens were found in decaying mushrooms and compost (pile of corncobs and cornhusks). Two individuals were captured in Lindgren funnel traps deployed in an old-growth northern hardwood forest. Adults were found in April, June, July, August, September, and October.
