A common crow butterfly (Euploea core) extracts nectar from the blossom on a high branch of a moringa tree in West Bengal, India. The common crow butterfly belongs to the crows and tigers subfamily Danainae found from South Asia to Australia. As caterpillars, this species sequesters toxins from its food plant which are passed on from larva to pupa to the adult. While feeding, it is a very bold butterfly, taking a long time at each bunch of flowers
