Phylogeny
The butterflies form the clade Rhopalocera, which is composed of three superfamilies: Hedyloidea (the moth butterfly family Hedylidae), the Hesperioidea (the skipper family Hesperiidae), and the Papilionoidea (the true butterfly families Papilionidae, Pieridae, Nymphalidae, Lycaenidae, and Riodinidae). All of these families are monophyletic. The Hedyloidea is the sister group to the other two superfamilies. Within the Papilionoidea, Papilionidae is the sister group to the other families, and Pieridae is the sister group to (Nymphalidae+(Lycaenidae+Riodinidae)). Phylogenetic hypotheses within the Nymphalidae are still under discussion. Current research is concentrated on subfamilial and tribal relationships, especially in the Nymphalidae.
