Earliest North American occurrence of Phyllotreta striolata (Coleoptera: Chrysomelidae) from Québec, Canada

Abstract A pair of elytra of the striped flea beetle Phyllotreta striolata (Fabricius) (Coleoptera: Chrysomelidae) was recovered from a sample of sediment dating before 1668 collected in Ville de Québec, Québec, Canada, making it the earliest recorded introduction of the species in North America. It is proposed that its transatlantic voyage took place on crucifers either voluntarily transported as foodstock and animal fodder or involuntarily as weeds.
