Neptis miah, the small yellow sailer, is a nymphalid butterfly found in India, Bhutan, Thailand, and Malaysia eastward to western China, Hainan and Guangdong.[1] [2] Seven subspecies have been identified. The Guangdong subspecies belongs to N. miah disopa Swinhoe and the Hainan subspecies is considered as N. miah nolana Druce.
The whole Neptini tribe is a difficult group and many species are alike. In fact, there may be a few unrecorded species flying in Hong Kong, which may be mistaken as the common N. hordonia or other brownish Neptis, like N. clinia Moore.
