Papilio nephelus sunatus

Black and White Helen Butterfly
The Black and White Helen is one of the subspecies of Papilio nephelus, native to South and Southeast Asia and Australasia. The Black and White Helen of Malaysia looks a little similar to the Red Helen topside but without the red markings and with additional white bars on the topside forewings. The above may instead be the similar subspecies P. n. albolineatus of Sumatra/Borneo?
