The butterfly is uncommon in montane forests at low elevations (Alt. 30 - 350m).
Some specimens from P. Thailand appear to be very close to ssp.saturata, with the blue area on the females being more purple and more extensive. However, the range of colour variation within these populations is wide and unstable. Further taxonomic and distibutional studies are needed, including the relationship to ssp.saturata.
