Since its discovery in Connecticut in 1934 (Britton 1934), the green immigrant leaf weevil, Polydrusus sericeus (Schaller) (Coleoptera: Curculionidae), has expanded its range in eastern North America. It is now present from Ontario to Prince Edward Island in Canada and ranges west to Minnesota and south to Connecticut, New York, Michigan, Illinois, and Ohio in the United States (Bright and Bouchard 2008; Coyle et al. 2008). We report the first records for P. sericeus in western North America, from British Columbia. It was discovered after an adult was submitted for identification to the second author in June 2011 by a concerned highbush blueberry (Vaccinium corymbosum L.) grower. He noted that similar weevils had been present in one field for at least the previous two growing seasons. Details of all collections are documented below under New Records.
