The Common Crow Butterfly, also called the Common Indian Crow, is one of the toxic Danaid family, native to South and Southeast Asia and Australasia.
The black and white body spots warn potential predators that these butterflies, whose caterpillars have eaten alkaloids, are distasteful and poisonous.
As a Danaid, it is mimicked by other butterflies such as the Common Mime and the female Great Eggfly as a defence against predators.
