Chilasa clytia (Linnaeus, 1758)
Common Mime
July 16-18, 1999 - Hong-Kong - Hong-Kong - China © Frédéric Vivien
I tentatively identified this butterfly to a Chilasa clytia of the form clytia. I do not see what it could be otherwise, looking at dabrera1982 or at the website of Hong-Kong lepidopterists.
