These represent the first records of species from Canada. Brachyleptura circumdata (Olivier) was common on flowers in silver maple flood plain forests. Yanega (1996) noted that the larval hosts are spruce, and possibly pine. Spruce occurred several kilometers from the sites where this species was most abundant.
