• Compsus auricephalus

  golden-headed weevil

  Compsus auricephalus is a broad-nosed weevil in the family Curculionidae, native to the southern United States and Central America. It is the northernmost species of the predominantly Neotropical genus Compsus and the only native representative of the genus in the USA. The species exhibits two distinct color morphotypes: a typical green form with pink to coppery head and legs, and a uniformly white to pale brown form. It shows considerable morphological variation across its range, including body shape, elytral apices, and pronounced sexual size dimorphism.
