This taxon has a very localized distribution and has only been found from Chumphon to Ranong. The butterfly is not rare in montane primary forests at low elevations (Alt. 20 - 150m). It is often seen flying gently in the dark areas inside the forest.
Ek-Amnuay ([2007],2012) recorded ssp.neptunus from Khao Phanom Bencha, Krabi, however it is considered doubtful. Hitherto no one has seen any specimens from Krabi area. Of course, it might be distributed in this region, but we need to confirm which subspecies it is by reliable specimens, because there is a possibility that it is ssp. manasukkiti. Further distributional research is needed in the future.
