Spherical, shiny and orange-yellow, laid on upper surface of leaves.The larvae and pupa are stated by Mackinnon to resemble closely the larva and pupa of "P. agestor'. Messrs. Davidson and Aitken's description of them is as follows:"Not unlike the larva of the "Ornithoptera" group in form, having similar rows of fleshy processes, but it is by far the handsomest "Papilio" larva we know, being of a dark umber-brown colour with a bright red spot at the base of each process, a dorsal row of large irregular yellow patches and a partial lateral row ending in a diagonal band which connects the two."
Velvet black or dark green. Has carmine spots. Has a dark red-brown longitudinal band and red spots. Two rows of sharp spines on segments 1 to 4 and single row on the others. The Osmeterium is light indigo-blue.The larvae feed on species of the Laurel family "Lauraceae"
