• Coptodisca

  Coptodisca is a genus of small moths in the family Heliozelidae, established by Walsingham in 1895. Species are leafminers whose larvae feed internally on leaves of woody plants, creating distinctive blotch mines. Several species have become invasive pests in Europe, particularly C. lucifluella and C. juglandiella on walnut (Juglans) and related trees. The genus is native to the Nearctic region with approximately 20 described species.
