Polyommatus kandura Sri Lanka, Myanmar, Taiwan, Hong Kong, Hainan, Mangulam Island, Sulawesi and the Philippines that belongs to the lycaenids or blues family.

Wet season form: Male has a bluish purple upperside. Forewing has base and basal half of costa flushed with pale blue; costa and termen edged by a slender dark brownish block even line, beyond which along the termen the cilia are brown, at base, white outwardly. Hindwing: costa somewhat broadly dusky black; a slender black conspicuous anteciliary line, beyond which the cilia are white traversed medially by a brown line; dorsum broadly pale brown, two subterminal pale bordered black spots in interspace 1, and one similar spot in interspace 2, often obsolescent and barely indicated. "Pale green at all stages, on the shade or the young leaves of the lime and pummelo bushes on which it feeds. When full grown it is about seven sixteenths of an inch in length, onisciform as usual; the head "black, smooth and shining, with a somewhat dark green dorsal line down the body, the whole surface but very slightly shagreened and covered with extremely fine and short downy hairs. The constriction between the segments slight. There are traces of two pale subdorsal lines, and there is a pale lateral line below the spiracles. The usual extensile organ on the twelfth segment short. This larva has no distinctive markings by which it can be easily recognized; it is altogether a very plainly coloured and marked insert. I have found it common in Calcutta during the rains, the ant which attends it betraying its presence. The latter has been identified by Dr. A. Forel as Camponotus rubripes, Drury (sylvaticus Fabr. ), subspecies conpressus, Fabr." (Lionel de Nicéville quoted in Bingham)
