Cethosia cyane euanthes

Fruhstorfer 1912 - The Leopard Lacewing

Koh Samui and Koh Pha Ngan.

A very common species on the islands. This species can be seen regularly in gardens and secondary growth. It has undertaken a rapid expansion in range over recent years. Since 1980, it has spread throughout the Malay Peninsular and has reached Singapore in the early 2000s.

The caterpillars are gregarious and very conspicuous, commonly found in large numbers on a species of passiflora. The spines are said to be urticating (gives a rash), and have very short barbs. The conspicuous colour means that the larvae are distasteful to predators, and it is likely that this is the case for all its stages.
