Notes
The butterfly is not rare locally in citrus plantations or gardens at low to moderate elevations.
The identification and distribution of nominotypical subspecies and ssp.tavoyanus in Thailand is still unclear. I follow Kimura et al.(2014) provisionally, however the populations from S.E.Thailand and Phetchaburi, P.Thailand might be ssp.tavoyanus. Further taxonomic study with a large number of specimens from various places is needed.
