Collection and habitat notes.

Coprophilus castoris was reported from inside beaver ( Castor canadensis Kuhl) lodges and collected during an evening flight (St. Andrews, N.B.) ( Campbell 1979). The recent New Brunswick specimens of this rare species were found among cobblestones and gravel on sand on a partially shaded cobblestone bar near the outflow of a brook into a river, and among gravel in a cold-shaded brook, and were collected with an aerial net during a late afternoon (15:00-18:00 h) flight. Adults were collected during April, May, and July.
