Charaxes psaphon, plain tawny rajah, is a butterfly in the family Nymphalidae. It was described by John Obadiah Westwood in 1847. It is found in the Indomalayan realm.
The fast flying Tawny Rajah travels at all levels through the forest. They only feed on rotting fruit, tree sap and faecal matter. Males are fond of mud sipping, but females are rarely seen on the ground. They engage in ‘hill topping’. This is a migrant species.
This butterfly is not an abundant species. It is more likely found in dry zone forests.
