Papilio (Chilasa) agestor, the tawny mime, is a swallowtail butterfly, native to Indian subcontinent and widely found across Asia.

Race govindra, Moore very closely resembles the typical form but can always be distinguished by the presence of a complete series of postdiscal bluish-grey spots on the upperside of the hindwing.

It is generally also smaller in both sexes than typical agestor, and on the upperside of the hindwing the ground colour in the anterior interspaces is broadly centred along the middle with very dark brown, almost black.

[1] The butterfly is found in Pakistan from west Kashmir to Sikkim and right across from Assam to Myanmar (including Nepal, Bhutan and Bangladesh), Thailand, Vietnam, Laos, Kampuchea, central and southern China and peninsular Malaysia.

The larva is at first of a reddish colour but very soon turns black and white, and lies on the upper surface of a leaf where it greatly and protectively resembles a bird's droppings."
