  Ravenous Leaf Beetles

  Orsodacnidae is a small family of leaf beetles (Coleoptera: Chrysomeloidea) that was historically classified as a subfamily of Chrysomelidae but is now recognized as distinct. The family contains two subfamilies: Aulacoscelidinae (genera Aulacoscelis, Janbechynea) and Orsodacninae (genus Orsodacne). Members of this family exhibit specialized feeding relationships with cycads and other plants, with documented seed predation by immature stages and folivory by adults.
