The Krishna Peacock (Papilio krishna) is a large swallowtail butterfly found in forests in China, North East India, Myanmar and Vietnam.
Resembles Papilio paris generally, but differs in many points as follows: Upperside: ground-colour more of a brownish black, irrorated similarly to parti with, green scales, but the scales smaller and more sparsely spread. Fore wing: the postdiscal transverse band well-defined, complete, formed of white scaling with only a thin sprinkling of green scales on its inner margin, generally erect or slightly curved, rarely slightly sinuous. Hind wing: upper discal patch metallic greenish blue, smaller than in paris, but the portions of it in interspaces 6 and 7 more extended towards the termen, the metallic golden-green band that joins tho patch on its inner side to the dorsal margin more conspicuous than in paris; the tornal ocellus as in paris, but above it a subterminal series of claret-red lunules in interspaces 2, 3, 4 and 5, followed by a series of ochraceous-red obscure terminal narrow lunules in the interspaces, the cilia on the outer margin of each conspicuously white. Underside: forewing as in paris but an erect ochraceous-white postdiscal band as on the upperside limits; the series of internervular pale streaks on the outer half of the wing. Hind wing: a well-defined discal ochraceous-white band formed of a series of somewhat lunular marks in the interspaces, these increase in width anteriorly; a subterminal series of claret-red lunules traversed by violet scaling on the inner side as in paris, but much broader and more prominent; finally a terminal series of ochraceous-yellow lunular marks in the interspaces ; the cilia that border each lunule white. Antennae, head, thorax and abdomen as in P. paris.
Generally found in the forests of the Himalayas where it flies from 3000 to 9000 feet. source
