Is found in India, Sri Lanka, China, Borneo, Japan, the Philippines, Thailand, and Australia. It was described by Johan Christian Fabricius in 1775.[2]

Larva is pale purplish brown. There is a yellow subdorsal line and white spots with a pale lateral line below them on the thoracic somites. Black-ringed ocelli can be seen on 4th to 10th somites, where the first two centered with blue, and posterior with purple. In the early instars, posterior ocelli are centered with crimson color with dorsal bands of yellow specks.[3] The species is found in open lowland habitats.[4] As the caterpillar crawls, it sweeps the tail-like horn, which is black and tipped in white, in an arc forwards and back.
Agriculture[]
They are often considered a pest on both busy lizzie () and fuchsias (Fuchsia sp.). Caterpillars of this species have also been seen feeding on arum lily (Zantedeschia aethiopica), Argentine trumpet vine (), climbing guinea flower (Hibbertia scandens), billy goat plum (Planchonia careya), godetia (Clarkia amoena), star cluster (Pentas lanceolata), Australian native violet (Viola hederacea) and slender grape (Cayratia clematidea). The larvae are black with yellow dots, they have a small spine on their tails and use it as a mimicked head. Before pupating the caterpillar will reach a length of about 70 mm.[5]
The adult is brown with light brown stripes down the thorax. The stripes are mimicked on the inner margin of the forewing.[6]
