Diagnosis

The fasciae are crimson red, straight, variable in width, and may or may not be edged black. The male has three black discal dots in a triangle, the female has only the more costal two of these, set longitudinally. In the male, the red bands may be expanded to more or less surround the discal spots. The hindwing varies from white to strong pink. The paler, less blackened individuals may be more frequent in open and coastal areas.

Biology

Records in Yunus & Ho (1980) and Zhang (1994) give the larval hosts as mosses and Hevea (Euphorbiaceae: rubber); the former is more likely, the latter possibly merely the substrate. However, Kuroko & Lewvanich (1993) recorded the larva of coccinea as feeding on leaf tissue of Dimocarpus (Sapindaceae); they illustrated the larva and cocoon.
