Each process is tapered and rounded at the tips. The ventral base of the clasper is smoothly tapered to an acuminate, black, dorsal process (Nimmo, 1971).
Larvae are detritovores, feeding on vascular plant tissues.
The range of this species extends from Great Slave Lake to British Columbia, New Mexico, Michigan and Maine. In Alberta, it is relatively common throughout the plains and lower major mountain valleys (Nimmo, 1971).
