Notes

The butterfly is uncommon in montane forests at moderate to high elevations (Alt. 1300 - 2200m). In the 1980s, it was very common to see many of them sucking water along streams in Nan, Thailand, however, recently their numbers have decreased significantly.
The markings of this taxon are very variable. I suspect it may be in the range of variation of ssp.belladonna. Further taxonomic study, including DNA analysis, is needed.
