Papilio chrapkowskoides

The blue or greenish median band of the upper surface is broad, 10—14 mm. broad at the hindmargin of the forewing, 10—17 mm. in the middle of the hindwing and distinctly widened posteriorly; the spot in cellule 2 of the hindwing always completely covers the base of the cellule and the spot in 1 c is very long and always reaches the cell. The green-blue spot in the cell of the forewing above reaches basad at least to the middle of cellule 2; forewing beneath without large yellowish submarginal spots, at the most with a few small spots near to the margin. Sierra Leone to the Congo region and Equatoria.[3]

The larvae feed on Calodendrum capense, Vepris, and Citrus species.[4]

Papilio chrapkowskoides nerminae is treated as a full species by some authors.

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:

• Papilio aristophontes Oberthür, 1897
• Papilio nireus Linnaeus, 1758
• Papilio charopus Westwood, 1843
• Papilio chitondensis de Sousa & Fernandes, 1966
• Papilio chrapkowskii Suffert, 1904
• Papilio chrapkowskoides Storace, 1952
• Papilio desmondi van Someren, 1939

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.[6]
