Arhopala bazaloides
Arhopala bazaloides, the Tamil oakblue, is a species of lycaenid or blue butterfly found in Asia. The Tamil oakblue is found India in, Myanmar , Sri Lanka and Thailand. Brief description

The light part of the hindwing beneath is so extensive that only the costal part remains darker spotted. Upper surface in both sexes of a deep purple
violet with a black marginal band of about 3 mm width in the male, being still broader in the female. Upperside : both wings deep purplish, with broad costal and posterior brown
margins. In the secondaries these borders are decidedly broader than in the primaries; abdominal fold brown. Tail brown, white-tipped, the nervures on each side of which are elongated and form two very short tails. Underside: both wings brown, with the spots margined with whitish. Description

The adults are small, often brilliantly coloured with electric blues, reds, and oranges. Females lay single, sea urchin shaped eggs on host leaves or flower buds; the resulting caterpillars are typically slug shaped. In many species, caterpillars depend on ants for protection, so caterpillars produce sugary secretions that are collected by the ants, in a symbiotic relationship. Most individuals overwinter in either the egg or pupal stage. The species was once considered as extinct from Sri Lanka, but rediscovered in 2014 from wet zone lowland forests of Sinharaja and Kanneliya. References
