Appearance
Male and female. Upperside black. Fore and hind wings with a discal broad transverse area from below vein 4 in fore wing to vein 2 on hind wing, a moderately large spot in interspace 5, a minute preapical dot beyond in interspace 6 on fore wing, and a subterrninal row of spots with two or three spots beyond them on the tornal angle of the hind wing, pale yellow, sometimes with an ochraceous, sometimes with a greenish tinge. The discal area on the fore wing nearly as broad in interspace 3 as on the dorsum, on the hind wing narrowing to an acute point on vein 2 at two-thirds of its length from base of wing. Tails touched with bluish grey. Underside with the discal transverse area and spot in interspace 5 as on the upperside; base and costal margin of the fore wing to apex, and base and dorsal margin of the hind wing broadly lilacine brown, on fore wing with two small black spots near base. Bordering the transverse discal area on the inner side, where it is margined with black lines, and above, is a broad chocolate carved band, continued more narrowly along the outer side of the discal area; beyond this on the fore wing is a concave series of dusky black lunules, on the hind wing the band itself is traversed by a line of obscure pale lunules; finally on the hind wing there is a subterminal series of internally white-bordered black spots followed by an obscure ochraceous terminal line, and above the tornal angle a slender transverse black line from vein 1 to dorsal margin.Wingspan 64–85 mm.
Distribution
It occurs in the Himalayas from Kashmir to Sikkim, the hills of Central India and the Eastern Ghats, the Western Ghats and Southern India, Ceylon, Assam, Cachar, and via Myanmar and the Tenasserim Hills far into Indonesia.
Habitat
Eggs are laid on various species of Fabaceae plants. These include acacias such as "A. caesia", "A. catechu" and "A. farnesiana", "Adenanthera pavonina", "Albizia" species such as "A. chinensis", "A. corniculata", "A. julibrissin" and "A. lebbeck", "Caesalpinia" species such as "C. bonduc", "C. major" and "C. regia", "Delonix regia", "Grewia" spp., "Leucaena leucocephala", "Peltophorum pterocarpum", "Pithecellobium clypearia" and "Pithecellobium dulce".At least on Borneo but probably elsewhere too, adults do generally not visit carrion or old fruit to drink liquids.
