Papilio xuthus, the Asian swallowtail, Chinese yellow swallowtail or Xuthus swallowtail, is a yellow-colored, medium to large sized swallowtail butterfly found in northeast Asia, northern Myanmar, southern China, the Korean Peninsula, Japan (from Hokkaidō to the Yaeyama Islands), Siberia and the Hawaiian Islands. It was also recorded in the state of Arunachal Pradesh, India, in 2014.
It mates multiple times in its life, leading to an increased genetic diversity in its young. It is preyed upon by a host of organisms, including the tree cricket Oecanthus longicauda, ant Lasius niger, and wasps (Polistes and Trogus mactator).P. xuthus utilizes color vision and color constancy while foraging for plants of the family Rutaceae.
It is common and not threatened.Papilio xuthus is common in urban, suburban, woods and orange orchards. The flight period is from May to August.
Males use both physical and visual cues to attract mates during the breeding season. Females of the species regularly mate with multiple partners. After mating, females use habitat and food quality to determine where they will oviposit their eggs.
Papilio xuthus is a member of the Papilio genus, of which Papilio appalachiensis, Papilio canadensis, and Papilio glaucus are also members. It is of the family Papilionidae and order Lepidoptera. It was first introduced in Hawaii in 1971 from Japan or Guam.P. xuthus makes significant seasonal migrations over 200 km. There are two subspecies of P. xuthus: Papilio xuthus koxingus and Papilio xuthus neoxuthus.
