Although uncommon, Euploea radamanthus is quite widespread throughout the region. Very little research appears to have been done into this species. Both sexes are similar in appearance but the background colour is slightly different and the female has larger areas of white on her wings. She is also slightly smaller in size. Males are more often seen than the females. They are also very skittish and difficult to approach.
