Taxonomy

There are over 20 Battus polydamas subspecies. 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.^{[citation needed]} Such errors may indicate that B. p. antiquus never existed at all, though this is disputed.

Description

Drury's illustration depicts a male. The ground color of the forewings and hindwings is black. The upperside of the forewings consists of a row of eight green spots. The upper four spots are small. The sixth one is the biggest. The row of spots on the hindwing is narrower.
