Eudocima cocalus

Eudocima cocalus

Diagnosis. The male forewing is similar to that of sikhimensis Butler (p. 256), but has the most distal ripple-mark concave distad rather than convex. The moth is much smaller and has a pale yellow hindwing that lacks an inner black lunule. Females are distinguished by large whitish blotches on the forewing discally, antemedially and tornally.

Taxonomic note. The Indian Subregion species hypermnestra Stoll is very similar but has the inner black lunule of the hindwing represented by two black patches. Zilli & Hogenes (2002) illustrated the genitalia of both species.

Geographical range. N.E. Himalaya, Sundaland and east to Australia and the Solomons.

Habitat preference. The species is not common, five specimens in recent surveys being recorded in lowland forest, four at Tawau in Sabah (200m) and one at Labi in Brunei (30-60m). There is older material without precise data from G. Marapok and G. Kinabalu in Sabah.

Biology. Moore (1881) illustrated a Javanese larva that is grey, irregularly variegated, the ocellate marks with paler grey rings and darker grey centres. The host plant recorded was Cocculus (as Epibatherium; Menispermaceae). A similar larva was illustrated by Semper (1896-1902) for the Philippines.
