The Common Crow (Euploea core) is a common butterfly found in South Asia. In India it is also sometimes referred to as the Common Indian Crow, and in Australia as the Australian Crow. It belongs to the Crows and Tigers subfamily of the Nymphalidae (Brushfooted butterflies). The Common Crow is the most common representative of its genus Euploea. Like the Tigers (genus Danaus), the Crows are inedible and thus mimicked by other Indian butterflies (see Batesian mimicry). In addition, the Indian species of the Euploea genus shows another kind of mimicry, Müllerian mimicry. Accordingly, this species has been studied in greater detail than other members of its genus in India. The Common Crow (Euploea core) is a glossy black butterfly with brown underside with white marks along the outer margins of the wing. The wingspan is about 8–9 cm and the body also has prominent white spots. Upperside dark brown, broadly paler along terminal margins; Fore and hind wing with subterminal and terminal series of white spots; on fore wing the former more or less oval, curved inwards opposite apex, the latter series often incomplete, not reaching apex, the spots smaller; often there is a small costal spot, and very rarely a spot in apex of cell and one or more discal spots; on the hind wing the inner series of spots are elongate, the outer conical. Underside similar, but ground-colour more uniform; cell, costal and discal spots on both fore and hind wing nearly always present. It is found in Sri Lanka, India, Myanmar and Australia. The butterfly, being protected by its inedibility, has a leisurely flight. It is often seen flying about shrubs and bushes in search of its host plants. It visits a large variety of flowering plant species. On hot days large numbers of these butterflies can be seen mud-puddling on wet sand. This butterfly also gathers on damaged parts of plants such as Crotalaria, Heliotropium to forage for chemicals precursors to produce pheromones. The protection mechanism
