Collection and habitat data.

In the Palaearctic region, Rugilus angustatus  occurs under decaying organic matter along forest borders and watercourses and in meadows ( Hoebeke 1995). In New Brunswick, adults of this adventive species were found along river margins, in hardwood and mixed forests, and in a beaver dam. Adults were found under loose bark in wood piles, among composted wood chips and decaying plant material, under overhanging sticks on the outer margin of a beaver dam, and in flood debris on a river margin. Two individuals were collected with an aerial net during evening flight (16:00-18:00 h) on a river margin. Adults were collected during April, June, and August.
