Subspecies and variation
Similar species
A distinctive species that is not easily confused with other species because of the transparency of the forewing. It has been suggested that the male is mimetic of Pachliopta polydorus, but their main resemblance are the red spots on the hindwing. The female is mimetic of Acraea andromacha, but differs obviously in wing shape and pattern.
