Hypolimnas bolina, commonly known as the Great Eggfly or Blue Moon butterfly, is a striking and widely distributed species in the Nymphalidae family. Native to tropical and subtropical regions, it is found across Asia, Australia, and the Pacific islands, inhabiting diverse habitats like forests, gardens, and open fields.
This butterfly is known for its sexual dimorphism. Males are especially striking, with velvety black wings adorned with iridescent blue or purple patches that resemble a full moon, surrounded by white margins. Females, on the other hand, have brown wings with a series of white and orange markings, mimicking toxic butterflies like Danaus chrysippus, offering them protection from predators. The wingspan ranges between 6 to 10 cm, making it a medium to large butterfly.
The lifecycle consists of egg, caterpillar, pupa, and adult stages. The caterpillars are black with spiny projections and feed on host plants like Asystasia, Ipomoea, and Ruellia. Adults are active pollinators, feeding on nectar from flowers like lantanas, marigolds, and hibiscus.
The Hypolimnas bolina is not only admired for its beauty but also for its ecological adaptability and mimicry. It plays a vital role in pollination and serves as a fascinating example of evolutionary strategies in butterflies.
