Collection and habitat data.

Most adults of Bassareus formosus in New Brunswick were swept from foliage of Comptonia peregrina in old fields and other forest openings during July and August. The repeated collection of Bassareus formosus fromthis plant suggests a close association with it that was not reported by Clark et al. (2004).
