Andaman Mormon (Female)

A Distinctive Endemic of the Andamans

The Andaman Mormon (Female) is one of the most remarkable endemic butterflies of the Andaman and Nicobar Islands. Evolving in the humid tropical rainforests of these geographically isolated islands, this species represents the unique biodiversity and high degree of endemism that characterize the region.

The commemorative postage stamp featuring the female Andaman Mormon highlights both its striking features and the importance of conserving such rare island species.

Physical Characteristics

The female Andaman Mormon has a wingspan of approximately 150 mm, making it larger than the male. Its body is black, but it can be distinguished by its prominent wing markings and structural features.

• Forewing: Marked with broad internervular streaks, white in the discal area.
• Hindwing: Interrupted by an oval black spot and a broad elongated black patch. The apical half of the tail is red, whitish at the tip.
• Colouration: The combination of black, white, and red markings gives the female a distinctive and elegant appearance.

Though not rare in the Andamans, females are notably difficult to sight, adding to their mystique.

Habitat and Ecology

The Andaman Mormon inhabits forested regions from North to South Andamans. It is a forest species closely associated with its specific larval food plant — a citrus climbing vine.

The species resembles the Great Mormon and is known to mimic the Andaman Club Tail, a fascinating example of adaptive survival in the wild. Such mimicry helps reduce predation and reflects the complex ecological relationships within the island ecosystem.

Conservation Importance

Given the fragile ecology of the Andaman and Nicobar Islands, the protection of endemic butterflies like the Andaman Mormon is vital. Several butterfly species of the islands are safeguarded under the Wildlife Protection Act, 1972, and conservation efforts are further supported by global assessments from the International Union for Conservation of Nature (IUCN).

Preserving forest habitats and host plants is essential to ensure the continued survival of this species.

Philatelic Significance

Through the issuance of this commemorative postage stamp, the Department of Posts honours the Andaman Mormon (Female) as a symbol of the rich and delicate biodiversity of the Andaman and Nicobar Islands. The stamp serves not only as a celebration of natural beauty but also as a reminder of the need for sustained conservation efforts to protect endemic wildlife.
