About the Common Castor Butterfly

Ariadne merione, the common castor, is an orange butterfly with brown lines whose larvae feed almost exclusively on castor (Ricinus communis). It is similar in appearance to Ariadne ariadne, the angled castor. This species is found in South and Southeast Asia. Their wingspan ranges between 30 and 35 mm. Like others in the family Nymphalidae, their front two legs are small and unused, effectively making them four legged. These smaller appendages are covered with long hairs, giving them the characteristic brush look.

Male: Upperside brownish ochraceous. Forewings and hindwings crossed by slender, somewhat obscure, very sinuous or zigzag dark basal, two subbasal and two discal lines disposed in pairs, followed by a single, sometimes double, postdiscal and a single subterminal slender line. All these lines more or less interrupted anteriorly on the hindwing, which has a smooth unmarked uniform appearance from costa to subcostal vein and vein 5. On the forewing there is in addition a series of obscure spots between the postdiscal and subterminal markings, arid a small white subcostal spot before the apex.
