"Papilio chrapkowskoides" is a member of the "Papilio" genus, of which  Papilio appalachiensis and "Papilio xuthus" are also members. "Papilio chrapkowskoides" belongs to a clade called the "nireus" species group with 15 members. The pattern is black with green or blue bands and spots and the butterflies, although called swallowtails lack tails with the exception of "Papilio charopus" and "Papilio hornimani". The clade members are: Description. Reflecting the confused separation between "Papilio bromius" and "P. chrapkowskii". Very similar to "P. chrapkowskii", but pale mottling and submarginal spots below not so well developed. Cilia of forewing black, not white, as in "P. chrapkowskii". A somewhat unstable race with frequent transitions to the  two previous races: "P. bromius" and "P. chrapkowskii".
