Graphium megarus megapenthes

Fruhstorfer 1902 - The Spotted Zebra

Koh Samui only.

A very rare species on Samui. I have only seen this species once. It is like a small Paranticopsis macareus, but whereas P. macareus has a single row of submarginal spots on the upperside hindwing, this species has two rows.

This species is thought to have two broods a year. However, both broods are in the Spring (Feb-March and March-April), as the larva will only feed on the current year's young shoots of its hostplant.

This is a forest species.
