Delias pasithoe parthenope

Wallace 1867 - The Red-base Jezebel

Koh samui and Koh Pha Ngan.

This species is rarely met here. It is known to have migratory tendancies, and that the fact that on the only two occasions I have seen this species, it has been just after strong winds from the mainland have buffeted the Island, leads one to suspect that it is not resident on these islands..

The larvae of this species is considered a pest in Sandalwood plantations where-ever its range meets that of that plant.
