Notes

The butterfly is not rare in montane dense forest mixed with bamboo at moderate elevations (alt.300m - 1100m) and often comes to rotten fruits that has fallen to the ground. They prefer in the dark jungle and suddenly fly out from below. Flight is fast and quickly fly away into the bush.
Examples from Central Thailand (Phetchabun and Chaiyaphum) are very interesting, both the shape of the wings and blue band on the UpF seem to be intermediate between the nominotypical subspecies and ssp.annamensis. And the hairtuft at the base of space 1a is small and inconspicuous as in ssp.annamensis. Okamoto et. al.,2013 also noted that two subspecies are found sympatric in Western Thailand.
The genitalia of ssp.amythaon, ssp.dilucida, ssp.annamensis and these populations are similar and could not find obvious difference between them. However further taxonomic study is needed.
