Graphium agamemnon agamemnon

Linnaeus 1758 - The Tailed Jay

Koh Samui only.

A common and widespread species, that can not be mistaken for any other species on the Island. It is a very swift flyer, and rarely settles, even when feeding.

The species can be found almost anywhere on the Island, from forest clearings to gardens, where it can be found feeding on Lantana flowers. The female is rarer than the male, but by no means uncommon, and can be distinguished by having longer hindwing tails.
