White Peacock Butterfly

The eggs of this species are small and green and found on the underside of host plant (Bacopa monniera) leaves. Caterpillars are black with silver or white dots and branched spines. The chrysalis is light green with small black dots. The upper side of the adult butterfly is white and contains a round black spot with a light-to-dark brown crescent-shaped trim on forewing. The hindwing has two spots similar to those on the forewing and is trimmed with the same crescent trim in brown to orange. The two front legs are non-functioning, giving the appearance of only four legs- characteristic of all members of the Nymphalidae family. In dry or winter seasons, the White Peacock becomes paler and larger. (Floridata, 2001; Struttmann, 2004)
