Life Cycle of the Leopard

The Leopard, Phalanta phalantha phalantha, is quite a common butterfly in Singapore. It is often found in parks and gardens on sunny days where its host plant, the Weeping Willow(Salix), is planted. The Leopard is usually spotted flying around weeping willows and nectaring on lantana and ixora.

The chrysalis. Coloured a beautiful pale green and edged with silver and shining red, it looks like an exquisite piece of jewellery. It can be surprisingly difficult to spot on the undersides of willow leaves where it is usually attached. The chrysalis becomes transparent to show the butterfly within just before its emergence.
