Leaf beetles (Chrysomelidae) are one of the most diverse beetle groups in the world.  Many species are specialist herbivores on particular species of flowering plants, and it is thought that the tremendous diversity of this group is due to a close evolutionary relationship with the flowering plants.  Here a leaf beetle feeds on a willow.
