The Cattleheart White (Archonias brassolis) is a butterfly in the family Pieridae and only member of the Archonias genus. It is found from Central America, south through most of South America.
The wingspan is 56-65 mm for ssp. rubrosparsa and 31-34 mm for approximata.
Although Archonias brassolis is a member of the Whites family, it is primarily black, with red hindwing patches and white forewing patches. It is geographically variable, with some forms being remarkable mimics of various Parides swallowtails, while others strongly resemble Heliconius. It is likely that these butterflies are themselves unpalatable and thus M?llerian mimics.
The larvae feed on Loranthaceae species and are gregarious. Adults of ssp. approximata have been recorded feeding on the nectar of Eupatorium species.
