There are 8 species in the genus Cupha,
commonly known as Rustics. The commonest and most widespread species
is erymanthis which occurs from India
and Sri Lanka to China, and south to the Philippines, Sumatra and
Java. The remaining species are distributed variously from the
Philippines to Australia.
Cupha prosope is found in New Guinea
and surrounding islands, and in Australia from Cape York to Brisbane
This species is found in open areas of rainforest, e.g. along forest
roads and riverbanks.
The egg is greenish-yellow and globular.
It is laid singly on
leaves of Flacourtia,
and Xylosma ( Salicaceae ). The fully
grown larva is greenish-brown, dotted with white. It has an orange
head and long black multi-branched dorsal and lateral spikes. The
chrysalis is green mottled with silver. It has 3 pars of dorsal
filaments, and long head horns, giving the impression of a fungal
growth sprouting from a larval corpse.
Both sexes nectar at
Lantana. Males commonly bask on the
ground in glades or forest roads.
