Notes

The butterfly is common in woodlands at low to high elevations (alt.200m - 2200m) and is occasionally seen in urban areas. Males are frequently observed coming to streams to suck water during the dry season in N.Thailand.
The records and photos from Phang Nga, P.Thailand in Küppers & Janikorn,2017 are interesting. Female photos of Pa-051 and 052 are definitely ssp.aeacus, but Pa-049 seems slightly approach ssp.malaiianus. It is likely to be a transition zone of both subspecies. Further distributional research with reliable specimens is needed.
