Andaman Mormon (Male)

A Pioneering Endemic Butterfly

The Andaman Mormon (Male) holds special significance as the first endemic butterfly described from the Andaman and Nicobar Islands. Flourishing in the humid tropical rainforests of the islands, this species exemplifies the unique biodiversity that has evolved due to the long geographical isolation and relatively undisturbed ecology of the region.

The commemorative postage stamp featuring the male Andaman Mormon celebrates this remarkable species and draws attention to the importance of conserving endemic island fauna.

Physical Description

The male Andaman Mormon has a wingspan of approximately 120 mm. Its body is entirely black, presenting a bold and striking appearance.

• Upper Side: Black forewings without internervular streaks; hind wings without tail and marked by a broad blue antediscal band.
• Underside: Black with a basal red streak on the forewing and obscure internervular veins.
• Hind Wing Markings: A distinct red patch, a complete red ocellus, and submarginal blue lunular spots, with the posterior ones less prominent.

The interplay of black, blue, and red markings gives the male a distinctive and attractive appearance in flight.

Habitat and Ecology

The Andaman Mormon is primarily a forest species, inhabiting areas from North to South Andamans. It is closely associated with its larval food plant, a citrus climbing vine, reflecting its dependence on specific vegetation within the island ecosystem.

The species resembles the Great Mormon and is also known to be mimicked by the Andaman Club Tail, illustrating fascinating adaptive relationships within the butterfly community.

Conservation Significance

Although the Andaman Mormon is not considered rare in the islands, the fragile ecology of the Andaman and Nicobar Islands necessitates continued protection. Several butterfly species of the region are protected under the Wildlife Protection Act, 1972, and conservation priorities are reinforced by global assessments from the International Union for Conservation of Nature (IUCN).

Safeguarding forest habitats and host plants is crucial for ensuring the survival of endemic species such as the Andaman Mormon.

Philatelic Importance

Through the issuance of this commemorative postage stamp, the Department of Posts honours the Andaman Mormon (Male) as a symbol of the extraordinary natural heritage of the Andaman and Nicobar Islands. The stamp not only highlights the beauty of this endemic butterfly but also underscores the need for awareness and conservation of the islands’ unique biodiversity.
