The Red or Common Lacewing Butterfly is native to South and Southeast Asia. It has many subspecies over its vast range. (The Red Lacewing of Australasia is a different species: Cethosia cydippe.) Above is the male, whose colour ranges from orange to bright red (the latter sometimes called the Viridis form). Unlike other Lacewing species, they have no white diagonal bar on the forewing.

Lacewing butterflies of Asia-Pacific are of the Heliconiini tribe and, like Heliconius butterflies of the Americas, the caterpillars eat passion flower vines to pass toxicity to the adult butterfly.
