Hypolimnas anomala, the Malayan eggfly or crow eggfly is a species of eggfly.

This species is present as various subspecies in South East Asia (Moluccas, New Guinea, Australia). It especially occurs in lowlands and tropical rainforests, wastelands, hill parks and natural reserves.

Hypolimnas anomala can reach a wingspan of 65 - 75 mm. These butterflies have brown forewings with a purple sheen. They show variable white markings. Usually there are a double row of white marginal spots and three pale streaks on each forewings. The hindwings are rather paler, with dark brown veins. The undersides of both wings are similar to the uppersides. In the adult butterflies only four legs are present. These butterflies mimic Euploea species.

Females lay golden in colour globular eggs in a large cluster on the underside of the leaves. They hatch after about 3–4 days. The 6th (and final) instarcaterpillars are black with yellow spots and spines. Also the head is yellow. with long black cephalic horns. They are gregarious and usually occur in large numbers. They feed on leaves of Urticaceae (Pipturus argenteus, Pipturus arboresceus, Pouzolzia, Villebrunea species ) and Euphorbiaceae (Claoxylon).
