Family - PAPILIONIDAE
Papilio xuthus, Yunnan, China
Back in the 18th
century when Linnaeus created the System Naturae, the word
Papilio was used as the genus name for
every known species of butterfly in the world. Since then much has
been learnt about the relationships between different species.
Consequently most have been reassigned to new genera, and only about
215 of the 17600 currently known species are retained in
found in Myanmar, China, Taiwan,
Korea, Ussuri, Amur, Japan, the Philippines and Hawaii.
This species inhabits woodland, suburban gardens, city parks and
Citrus orchards, at elevations between
sea level and about 1000m.
