The Great Yellow Mormon is also called Asian Swallowtail (confusingly, as others have this name, including the Chinese Yellow Swallowtail, Papilio xuthus) and the Sunset Swallowtail. Native to Indonesia, Borneo and the Philippines, its wingspan can reach 125mm/5 inches. The females (above) and males (below) look very different and the female has many different forms.
