The variable cattleheart (Parides erithalion) is a North and South American butterfly in the family Papilionidae. The species was first described by Jean Baptiste Boisduval in 1836. The upperside of the wings is black with a row of red postmedian spots. The underside of the wings is also black with a row of pink and whitish spots. In males of some subspecies the uppersides of the forewings have a large olivaceous-green patch from the inner margin forward, with a creamy-white spot, while hindwings have a band of three red spots. Fringe in both sexes is dotted with white.
