Cethosia

Cethosia is a genus of brush-footed butterflies belonging to the family Nymphalidae. These butterflies are commonly known as the lacewings. The genus is primarily found in Southeast Asia, with some species extending into parts of the Indian subcontinent and the Indo-Malayan region. Cethosia species are characterized by their vibrant orange and black wing patterns, often with intricate markings that mimic the leaves of their host plants, providing effective camouflage.

The wings of Cethosia butterflies are typically broad and somewhat rounded. The upper surfaces are usually a striking combination of bright orange, deep black, and sometimes white or reddish markings. The undersides often display a more subdued pattern of brown and grey, designed for concealment when the butterfly is at rest with its wings closed. This sexual dimorphism is common, with males often being more brightly colored than females.

The larval stage of Cethosia butterflies, the caterpillars, feed on various species of Passiflora, commonly known as passion flowers. Adult butterflies feed on nectar from a variety of flowering plants. Cethosia species are generally solitary and are often observed flying in open, sunlit areas, such as forest clearings, gardens, and along the edges of woodlands. Their flight is typically strong and direct.
