Chrysomeloidea

The Chrysomeloidea are an enormous superfamily of beetles, with tens of thousands of species, mostly in the families Cerambycidae (the long-horned beetles) and Chrysomelidae, the leaf beetles. Several species in these two families are important plant pests. The spotted cucumber beetle is a serious pest of vegetables and is a very common insect on all sorts of flowers. The Colorado potato beetle, Leptinotarsa decemlineata, attacks potatoes and other members of the Solanaceae. The Asian long-horned beetle is a serious pest of trees where it has been introduced. Some authorities have suggested removing the Cerambycidae and related families (Disteniidae, Oxypeltidae, and Vesperidae) from Chrysomeloidea to create a separate superfamily 'Cerambycoidea' (e.g.,), but in the absence of evidence to support the monophyly of the resulting groups, this proposal has not yet been accepted by the scientific community.
