Polyura is the genus of nawab butterflies. They are native to the Indomalaya and Australasian ecozones that belong to the brush-footed butterfly subfamily Charaxinae, or leafwing butterflies. Like the large and conspicuous pasha and rajah butterflies ( Charaxes) they belong to the Charaxini tribe. Recent genetic research has shown that some species of the genus Charaxes are more related to Polyura than to other Charaxes species. Polyura should therefore be included in Charaxes.
