The eggs, globular reddish, are laid on leaves of climbing vines of the Aristolochia (Aristolochia foveolata). The legs are laid one egg per leaf on the tips of the vines leaves. A fully-grown caterpillar is dark greyish brown with a light grey saddle mark on the back. Buff and grey tubercles cover the whole extent of the body. The larvae of the Rajah brooke's Birdwing Butterfly are voracious eaters but their movement is very slow. Once they defoliate a certain leaf, they move on to the other and sometimes starvation might lead to cannibalism. The caterpillars have an osmeterium behind the head that secretes a pungent fluid, which deters potential predators. The caterpillars are very unappealing and toxic due to their feeding habits. Caterpillars concentrate this aristolochic acid in their tissues up until they attain adulthood.
The pupa is apple green with violet markings. It is attached by the cremaster and silk girdle to the vine stem vertically. "Scientific name for butterfly Lepidoptera".
