Monkey Puzzle (Rathinda amor)

The Monkey Puzzle (Rathinda amor) is a distinctive small butterfly belonging to the family Lycaenidae and is the only species in the genus Rathinda. It occurs in Sri Lanka and parts of South Asia, including India, Bangladesh and the Western Ghats. The adult has a characteristic brownish-black coloration with a subtle violet sheen on the upper wings. The forewing bears prominent white spots, while the hindwing has dark lunular markings associated with orange and metallic blue-green markings and several delicate tail-like extensions. The tails are black with white tips, and the antennae are black with pale rings and an orange-tipped club. Females are generally similar to males but tend to have larger white spots on the upper forewings. The underside is predominantly white or slightly yellowish, intricately patterned with pale chocolate-brown markings, orange-yellow bands and small metallic blue-green spots, giving the butterfly a remarkably cryptic and complex appearance when resting among vegetation. he Monkey Puzzle is typically associated with moderate- to high-rainfall forests, scrub forests and their edges, generally at elevations below about 900 m, and it prefers low vegetation, forest undergrowth, paths and clearings. It may also occur in gardens where suitable larval food plants are present. Adults are relatively weak and low-flying, rarely remaining airborne for long; after landing, they characteristically turn, sidestep and repeatedly move their tail filaments, a behavior thought to make it difficult for predators to identify which end of the butterfly is the head. The caterpillar is pale green with fleshy reddish projections along its back, while the green chrysalis gradually becomes brownish as it approaches maturity and remains attached to foliage by a stalk at its posterior end. Larvae have been recorded feeding on plants from several families, including Sapindaceae, Myrtaceae, Euphorbiaceae, Rubiaceae, Dipterocarpaceae and Loranthaceae, with plants such as Ixora (Ixora coccinea) and mango (Mangifera indica) among the recorded food plants. These close associations with vegetation, together with its unusual tail-wagging behavior and intricate wing markings, make the Monkey Puzzle a particularly fascinating member of Sri Lanka’s butterfly fauna.
