Brush-footed butterfly of subfamily Charaxinae

The superfamily Papilionoidea (from the genus Papilio, meaning "butterfly") contains all the butterflies except for the skippers, which are classified in superfamily Hesperioidea, and the moth-like Hedyloidea.

A proposed phylogenetic position of the Papilionoidea is as follows:^[1]

Some authors treat this group as a series Papilioniformes within a single superfamily that also includes the skippers. However not all authors agree that all the butterflies constitute a single clade. The skippers are significantly different from the other butterflies. The members of the Papilionoidea may be distinguished by the following combination of characters:

• the body is smaller and less moth-like.
• the wings are larger.
• the antennae are straight and clubbed (rather than hooked as in the skippers).
• the caterpillars do not spin cocoons to pupate in.
• the pupae are angular rather than rounded.

Families of Papilionoidea

The five well-supported families of Papilionoidea are:

• Swallowtails and Birdwings, Papilionidae
• Whites or Yellow-Whites, Pieridae
• Blues and Coppers or Gossamer-Winged Butterflies, Lycaenidae
• Metalmark butterflies, Riodinidae
• Brush-footed butterflies, Nymphalidae which contain the following 13 subfamilies:
  • the snout butterflies or Libytheinae (formerly the family Libytheidae).
  • the Danaids or Danainae (formerly the family Danaidae).
  • the Tellervinae.
  • the glasswings or Ithomiinae.
  • the Calinaginae.
  • the morphos and owls or Morphinae (including the owls as tribe Brassolini).
  • the Browns or Satyrinae (formerly the family Satyridae).
  • the Charaxinae (preponas and leaf butterflies).
  • the Biblidinae.
  • the Apaturinae.
  • the nymphs or Nymphalinae.
  • the Limenitidinae (especially the adelphas) (formerly the family Limenitididae).
  • the tropical longwings or Heliconiinae.

Of the subfamilies of Nymphalidae, only the Morphinae and Satyrinae are possibly paraphyletic, but these two subfamilies form a strongly-supported clade with the Charaxinae as sister-group.^[2]

The fossil genus Lithopsyche is apparently a Papilionoidea incertae sedis which has long been mistaken for a geometer moth of the Boarmiini. It is variously placed in the Lycaenidae or Riodinidae. A similar fossil, Lithodryas, is more firmly assigned to the Lycaenidae, but might belong to the Nymphalidae. Riodinella, yet another prehistoric genus, also seems to belong here, but its relationships are quite obscure indeed. However, these fossils – all found in Eocene deposits dating roughly between 50 and 25 million years ago – suggest that the radiation of the Papilionoidea into the present-day families took place during that epoch. Prodryas, from the end of the Eocene, can be quite robustly assigned to the Nymphalidae, and is in fact quite likely a member of the Nymphalini. Oligocene fossils of Papilionoidea are usually assignable to an extant family without problems.

Taken together, these fossils place the origin of the Papilionoidea in the latest Mesozoic or early Paleogene, while the extant families emerged approximately the early Eocene onwards.
