Haplorhynchites is a genus of leaf and bud weevils in the family Attelabidae, comprising ten recognized species. The genus is best known through Haplorhynchites aeneus, commonly called the sunflower head-clipping weevil, which exhibits a distinctive reproductive behavior where females girdle plant stems below the flower head to facilitate larval development. Members of this genus are associated with prairie ecosystems and sunflower plants, with most species described from North America.
