This is the first record from Thailand. The first discovery was taken photo by Antonio Giudici on 4.Mar.2020 in Umphang Dist., Tak.
The butterfly was found around small stream in montane forests at moderate elevations and appears to be a very local species. Males occasionally come to the banks of streams and puddles to suck water.
