 Food plants known to be utilised by the larvae are "Aristolochia acuminata", "A. indica", "A. pubera", "A. thoszetti", "Pararistolochia australopithecurus", "P. deltantha" and "P. sparusifolia".The leaves of the introduced Dutchman's pipe ("Aristolochia littoralis") will kill the larvae of this species and several other swallowtail butterflies in Australia.Consequently, it is discouraged to plant Dutchman's pipe in Queensland, New South Wales and the Northern Territory.
