See text Cethosia cydippe, the eastern red lacewing,[1] is a species of butterfly from Australia, New Guinea and nearby islands.

The imagines have scarlet wings with thick black edges and a diagonal white patch on the forewings.

[2] The pupae are brown and spiky with black and gold markings, hang from a cremaster and resemble a dead leaf.

Although the Principle of Priority in zoological nomenclature would normally require the oldest name to be used, the 1767 name has been conserved against any earlier homonyms.

The subspecies is endemic to Queensland, where it is found in the northern Gulf Country and north-east coastal region.
