Otiorhynchus (sometimes misspelled as Otiorrhynchus) is a large genus of weevils in the family Curculionidae. Many species of the genus, particularly the black vine weevil (O. sulcatus) and the strawberry root weevil (O. ovatus), are important pests, both as larvae and as adults. Larvae feed on plant roots.
