"Euploea core," Wikipedia, the free encyclopedia. Euploea core, the common crow, is a common butterfly found in South Asia to Australia. In India it is also sometimes referred to as the common Indian crow, and in Australia as the Australian crow. The common crow is a glossy-black butterfly with brown undersides with white markings along the outer margins of both wings. The wingspan is about 8–9 cm and the body has prominent white spots. The male has a velvety black brand located near the rear edge on the upperside of the forewing. On the underside there is a white streak in the same location. This white streak is present in both male and female. In its natural position this streak is hidden behind the hindwing and can be seen only when the butterfly is captured and observed closely.
