The world's first bisexual butterfly to be bred in captivity has been cultivated at a Singapore nature park, newspaper The Straits Times reports.

A Papilio Memnon with both female and male parts was discovered on Monday local time, at the Butterfly Park on Sentosa Island, the daily reported senior curator Ithnine Atan as saying.

Mr Atan said such occurrences are very rare in the wild and had never been recorded in captivity.

The butterfly's female parts are distinguished by red and white patches on its wing, broader wings, a longer antennae and a bigger abdomen to hold eggs.
