The homeotic specimen of Papilio aegeus ormenus, showing the undersides of the wings. The homeotic aberration is bordered by the discocellular cell and veins M2 and CuA1. Note that the distorted pattern on the hindwing is independent of the homeotic markings on the forewings, and is more likely caused by damage sustained by the pupa during ecdysis from the fifth instar.
