Cethosia cyane, commonly known as the leopard lacewing, is a vividly patterned butterfly found in South and Southeast Asia, especially in countries like India, Malaysia, and Indonesia. This butterfly is part of the Nymphalidae family and is renowned for its intricate wing patterns and bright colors. The upper side of its wings displays a striking contrast of orange and black with white spots, while the underside reveals a lace-like pattern of orange, white, and black, giving it a delicate, ornamental appearance.
The leopard lacewing inhabits tropical and subtropical forests and can often be spotted in gardens and open woodlands. It feeds on nectar from a variety of flowering plants, contributing to pollination within its ecosystem. Cethosia cyane undergoes a complete metamorphosis, and its caterpillars are typically red and yellow striped with black spines, feeding on plants from the Passifloraceae family, such as Passiflora and Adenia. These host plants contain toxins, which the caterpillars ingest and retain throughout life, making them distasteful to predators in all stages but particularly as adult butterflies.
With its bold coloration and complex patterns, Cethosia cyane is admired by butterfly enthusiasts and plays an essential role in the biodiversity of its native habitats. While it is not currently threatened, habitat loss could pose risks to its population in the future.
