Danaus chrysippus, also known as the plain tiger or African monarch, is a medium-sized, butterfly widespread in Asia and Africa. It belongs to the Danainae (milkweed butterflies) subfamily of the brush-footed butterfly family, Nymphalidae. Its colouration 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 archetypal danaine of India. Accordingly, this species has been studied in greater detail than other members of its subfamily occurring in India.
D. chrysippus is a medium-sized butterfly with a wingspan of about 7–8 centimetres (2.8–3.1 in). The body is black with many white spots. The wings are tawny, the upperside brighter and richer than the underside. The apical half of the forewing is black with a white band. The hindwing has three black spots around the center. The hindwing has a thin border of black enclosing a series of semicircular white spots.
Background colour and extent of white on the forewings varies somewhat across the wide range; see Systematics and taxonomy below.
The male plain tiger is smaller than the female, but more brightly coloured. In addition, male danaines have a number of secondary sexual characteristics. In the case of the plain tiger, these are:
The range of the plain tiger extends from Africa and southern Europe, eastwards via Sri Lanka, India, and Myanmar to China, Java and Sulawesi. It is a very common species.
Despite the external similarity, the common tiger (D. genutia) is not closely related to this species. Three subspecies were considered valid in a 2005 review:
