Appearance

The wingspan is 56–65 mm for ''A. b. rubrosparsa'' and 31–34 mm for ''A. b. 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 Müllerian mimics.
