The Krishna Peacock (Papilio krishna) is a large swallowtail butterfly found in forests in China, North East India, Myanmar and Vietnam.

Description

A large beautiful butterfly with a prominent swallowtail, the Krishna Peacock has a wingspan of 120 to 130 mm.
It has black upper forewings with a thin prominent yellow discal band running across the wing, parallel to the body.
The upper hindwing has a large blue discal patch which tapers off into a greenish yellow band from its lower edges inwards towards the dorsum. It has a series of red mauve capped crescents (usually 5 in number).
The upper hindwing discal band appears on the underhindwing also as a prominent curved yellow discal band.

Male upper (left half) and underside (right half)

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.^[1]
