Description
The sexes are different and the female occurs in many districts in two forms. Tail narrow, pointed. Hindwing above with narrow bluish submarginal crescents, beneath with a regular row of reddish yellow crescents between cell and outer margin. Female ''P. androgeus'' has on the forewing two large yellow patches, sometimes also a small spot; in the female ''P. piranthus'' these spots are wanting or are merely indicated, the metallic scaling of the hindwing is not dense and extends into the cell.Jordan, K. , in Seitz, A.

Adults are on wing from April to October in multiple generations per year. The larvae feed on the leaves of ''Subspecies
*''Papilio androgeus androgeus'' – (Suriname, Colombia, Ecuador to Bolivia, Brazil (Amazonas, Pará, Mato Grosso)) *''Papilio androgeus epidaurus'' Godman & Salvin, 1890 – (Florida, Mexico, Panama, Cuba to Santa Lucia) male: the yellow area very broad: female: forewing with indications of a yellow band outside the cell; the grey-blue scaling on the hindwing dense. *''Papilio androgeus laodocus'' (Fabricius, 1793) – (Brazil (Minas Gerais, Paraná), Paraguay, Argentina) the yellow area of the male is pale, the small spots placed before the extremity of the cell are smaller and often entirely wanting. Only one female known; this is similar to the female ''androgeus'' of the nominate subspecies, but the upper yellow spot is smaller than the second.Threats
