• Chrysochus

  dogbane leaf beetles, milkweed beetles

  Chrysochus is a genus of leaf beetles in the subfamily Eumolpinae, established in 1836 by Louis Alexandre Auguste Chevrolat. The genus name derives from Greek χρυσοχόος, meaning 'goldsmith,' referencing the striking metallic coloration of its members. The genus contains at least eight described species distributed across North America, Europe, and Asia, with six species in the Palearctic realm and two in North America. Species in this genus are specialized herbivores of plants in the dogbane and milkweed families (Apocynaceae and Asclepiadaceae).
