Collection and habitat data.

This adventive species is often found in decaying plant material, decaying vegetables, cow dung, and decaying leaves ( Hoebeke 1995). In New Brunswick, this species was collected from under drift material along river margins, in compost (decaying vegetables), and among decaying corncobs and cornhusks. Adults were also collected in flight with an aerial net during a late afternoon (15:00-18:00 h) flight near a mixed forest and along a trail in a mixed forest. One adult was captured in a Lindgren funnel trap in a mature hardwood forest. Adults were captured during April, May, June, and August.
