Palaearctic seed beetle (Coleoptera, Chrysomelidae, Bruchinae) new to North America, arrival, distribution, and autecology.

First North American records are presented for Frölich, 1799 (Coleoptera, Chrysomelidae, Bruchinae), as confirmed by morphology from multiple sites in Canada: British Columbia, Ontario, and Québec. Diagnostic information is presented for in North America. This insect is expected to reduce plant reproductive output in infested L., L., and other potential (Fabaceae) hosts. Impacts on broad bean ( L.) production are expected to be small. Potential reproductive impact on native North American species remains unknown. The United States of America and Canada are now known to be home to 69-79 species of adventive Chrysomelidae including 16-18 Bruchinae. We have found two dead, teneral individuals inside seeds imported from Europe, and we hypothesise that this species was introduced to Canada from Europe via seeds for planting sometime before 2007. At our study sites, flowering began in mid June followed by oviposition in late June with first adults emerging in late August, requiring about 60 days from egg to adult stage. (Rodani, 1877) (Hymenoptera, Pteromalidae) was newly recorded as parasitoid of in Canada, and caused about 10% mortality in at our sites.
