Pathysa antiphates itamputi

Butler 1885 - The Fivebar Swallowtail

Koh Samui and Koh Pha Ngan.

One of two species of 'Swordtails' found on Samui, and by far the commoner. This is primarily a forest species and can be found flying close to rivers and streams.

When resting, with its wings closed, it can not be mistaken for any other species, with its green colouring. However, in flight, its rapid wing movements make it easily mistaken for a Pierid butterfly. The males of this species love to puddle, and at times, large numbers can be found congregated around a single damp patch.
