Danaus chrysippus, known as the Plain Tiger or African Monarch, is a common butterfly which is widespread in Asia and Africa. It belongs to the Danainae ("Milkweed butterflies") subfamily of the brush-footed butterfly family, Nymphalidae. It is a medium-sized, non-edible butterfly, which is mimicked by multiple species.
The Plain Tiger is believed to be one of the first butterflies to be used in art. A 3500 year old Egyptian fresco in Luxor features the oldest illustration of this species.
The Plain Tiger can be considered the archetypical danaine of India. Accordingly, this species has been studied in greater detail than other members of its subfamily occurring in India.
