Welcome to Papilionoidea of the World

This is a new ScratchPad about the Papilionoidea of the world. We will use it to provide a working check list of the butterflies of the world (Papilionidae, Hedylidae, Hesperiidae, Pieridae, Nymphalidae, Riodinidae and Lycaenidae) and basic information about their distribution and hostplant associations.
