There are over 20 Battus polydamassubspecies. While many are considered rare, B. p. antiquus is the only subspecies currently listed as extinct. Dru Drury received his butterflies from a variety of sources during a period of history when cartography was not precise. There exists, to those who have examined his three-volume work Illustrations of Natural History, a plethora of errors in his taxonomy. Such errors may indicate that B. p. antiquus never existed at all, though this is disputed.
