Euploea radamanthus, the magpie crow, is a butterfly found in India and Southeast Asia that belongs to the crows and tigers, that is, the danaid group of the brush-footed butterflies family.


Male forewing: dorsum and termen very convex; costa arched. Female forewing: differs only in being narrower and the dorsum sinuous. Hindwing in both sexes: costa and termen strongly curved, forming together half of an ellipse of which the straight dorsal margin is the chord. Male. Upperside black, the forewing with a brilliant blue gloss throughout, the base brown; hindwing: the upper portion silky hair-brown, the disc and terminal margin shot with blue. Forewing: a very large, irregular, white spot filling the apex of the discoidal cell, three elongate spots divided by the nervures above and one or two small white spots below, the whole forming an irregular oblique bar; a large sub-terminal blue spot in interspace 2 and smaller similar spots in interspaces 4-7; finally a line of 3 or 4 small terminal blue spots near the tornus: all these blue spots occasionally white-centred. Hindwing: broad white streaks in interspaces la, 1b, 1 and 2, a spot (sometimes absent) at base of interspace 3, another (but rarely) at base of interspace 4, one or two discal blue spots and very incomplete subterminal and terminal series of similar spots. Underside hair-brown, the markings as above but more complete .and larger; on the hindwing there are in addition one or two spots or streaks in the cell and on the disc beyond it. Female upperside pale umber-brown, the apical half of the forewing with or without blue gloss; markings similar to those of the male, but all of them white and somewhat larger, especially the two spots at the lower end of the oblique baron forewing; on the hindwing there are in addition three white streaks in the cell with two or three spots beyond, the subterminal and terminal series of spots white and generally complete. Underside similar, the markings broader. Antenna black; head, thorax and abdomen in male bluish black, in female cinereous; in both sexes the palpi and thorax beneath spotted with white, the abdomen transversely barred with the same colour.[1]

Race ramsayi, Moore (Eastern Himalayas). Differs in being on the whole larger, with the white markings of great width, in the female almost entirely filling the cell in the hindwing. In both sexes streaks are always present in interspaces 3 and 4 of the hindwing, while the sub-terminal and terminal series of spots on that wing are generally complete. The female in all the specimens I have examined has a decided blue gloss on the apical half of the forewing.[1]


Eastern Himalayas and into the Malay region.
