A Tawny Coster butterfly was observed feeding on nectar along the water’s edge at the Vettaiperumal Temple tank. Scientifically known as Acraea violae, the Tawny Coster is a familiar yet striking butterfly found widely across India and South Asia. Its bright orange wings, marked with distinct black spots, make it easily recognisable. With a wingspan ranging between 53 and 64 millimetres, it is a medium-sized butterfly commonly seen in gardens, open fields, roadsides, and rural and semi-urban areas.
The Tawny Coster is known for its slow, floating flight, often flying close to the ground or resting on flowers while feeding on nectar. During its larval stage, the caterpillar feeds primarily on passion flower (Passiflora) leaves, completing a life cycle that progresses from egg to caterpillar, pupa, and finally to butterfly.
The Tawny Coster plays a great ecological role as a pollinator. Its adult lifespan is relatively short, lasting about two to three weeks. But during this period, it contributes significantly to plant reproduction and biodiversity.
