In the Neartic region, this species can be very abundant along the margins of streams, ponds and lakes, but has only been reared infrequently. The pupa was described by Grogan & Wirth (1979). In Argentinian Patagonia, P. subaspera was collected in Villa Regina from the margins of the large Río Colorado, and a deep pond alonside a road in northern Chubut province.
