Tawny Rajah (Charaxes psaphon)

Rather uncommon butterfly flies all over the island except in the higher hills. It is much common in the dry zone especially during the south-west monsoon and scarce in the wet zone. Both sexes especially males settle on wet patches, bird droppings, decaying animal matters and rotting fruits. It is a very fast flier and also take part in migrations. Hill-topping phenomena is also observed of male Tawny Rajas*. According to the sources females are rarely seen, since they are less active and preferring to sit deep in the foliage. Larva feeds on Croton laccifer (ගස් කැප්පෙටියා),  Dalbergia pseudo-sissoo (බඹර වැල්),  Croton aromaticus (කැප්පෙටියා)  and Entada rheedii (පුස් වැල්)

* Male flying up to and staying on a hill top waiting for females.
