New Butterfly Record for Sri Lanka

On February 16, 2008, Dr. Michael van der Poorten identified a species of butterfly new to Sri Lanka – the Orange Migrant, Catopsilia scylla.

Catopsilia scylla is found in Malaysia, Australia, Singapore, Indonesia and Borneo but had never been recorded in Sri Lanka. Male and female adult butterflies were seen flying in the North Western Province of Sri Lanka; eggs, larva, pupae and pupal cases were also found in abundance on shrubs of Cassia surattensis, its principal larval host plant in the island.

Cassia surattensis is not native to Sri Lanka but has been introduced and planted along roadways.
