Commander

The Commander is a tiny yet striking forest butterfly found throughout Sri Lanka, especially common in the lower wet zone. With a wingspan of around 30 mm, both males and females share a similar appearance. The upper side of the wings is rich reddish-brown, marked by a bold oblique white band that breaks into patches toward the upper margin. Red bars outlined in black stand out on the forewings, while darker brown marginal bands are more pronounced on the hindwings. The underside shifts into softer tones, with a bluish-grey base fading into greyish brown, carrying a muted version of the upper wing pattern. Despite its small size, the Commander is quite eye-catching when it glides through sunlit forest paths and stream edges.

This species is closely tied to forest habitats and is often seen in sunny clearings as well as darker, shaded areas where it searches for larval food plants. Adults mainly feed on fallen fruits and tree sap, though they also visit flowers and are frequently observed feeding on Melastoma malabathricum fruits along rainforest tracks. Males occasionally engage in mud-sipping but do so alone rather than in groups. Females carefully lay eggs at the tips of leaves, a behavior that supports the feeding habits of the caterpillars. The larvae depend on plants from the Rubiaceae family, including Mussaenda frondosa, Wendlandia bicuspidata, and Mitragyna parvifolia, making the Commander an intimate part of Sri Lanka’s forest butterfly communities.
