Eudocima homaena Eudocima homaena (Christmas I.)

. There is marked sexual dimorphism in forewing pattern. Males have it variegated and transversely rippled purplish brown, with a shallowly sigmoid postmedial and straight antemedial. Females have a similar ground colour, but the pattern is more irregular and is disrupted by a broad green streak much as in the next two species but with a more angular shape.

Geographical range. Indian Subregion, Taiwan, Nicobars, Peninsular Malaysia, Borneo, Philippines, Christmas I.

Habitat preference. Records range from the lowlands to 1930m, but the species is more frequent in the lowlands. Females are much rarer in light-trap samples.

Biology. The larva has been described and sometimes illustrated, usually under its synonym, ancilla, by Moore (1881, 1884-1887), Mathur (1942) and Bell (MS). It is a deep, velvety blackish brown or purplish brown, often greyer dorsally, with the setae on minute blue spots. The ocelli are centred azure-blue within black surrounds and ringed with yellow, and there are irregularly sized lateral yellow patches laterally on A1, A6, A7 and A8, the largest being on A6, and that on A1 being in line with the ocelli. The hump of A8 is red in the illustration by Moore (1881).

Host plants recorded (Robinson
et al., 2001) are Achyranthes (Amaranthaceae), Cocculus, Cyclea, Menispermum and Tiliacora (Menispermaceae).
