Papilio xuthus
species of insect
Papilio xuthus, the Asian swallowtail, Chinese yellow swallowtail, Japanese swallowtail, Korean swallowtail or Xuthus swallowtail, is a yellow-colored, medium to large sized swallowtail butterfly found in northeast Asia, northern Myanmar, southern China, Taiwan, the Korean Peninsula, Japan (from Hokkaidō to the Yaeyama Islands), Siberia and the Hawaiian Islands. The butterfly has been observed thrice in New Zealand. Once in Dunedin in 1996 emerging from a chrysalis in a car yard specializing in Japanese used cars; it is thought the chrysalis arrived through one of the cars. and later in Auckland in 2011 and 2016. 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.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Papilio xuthus”, the useful work is to connect “species of insect” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 12, 2026. The linked authority identifier is Q132092. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1996, 2011, 2016 and 2014.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
