Habitat & Habits
The Swordtails are remarkable for the very long, slender and tapering tail on the hindwing. They are forest butterflies and are very swift on the wing, with an erratic flight. They are often mistaken for a white Pierid butterfly, as the tails are usually not seen during flight.
This species is the only representative of the genus Pathysa in Singapore. It is credited with being one of the few butterflies in the region to bear a local name - itamputi, from the Malay words "hitam", meaning black, and "putih", meaning white.
