Papilio nireus, the green-banded swallowtail, narrow-banded blue swallowtail, or African blue-banded swallowtail, is a butterfly of the family Papilionidae. It is found in Sub-Saharan Africa.
Description
[edit]The wingspan is 75–90 millimetres (3.0–3.5 in) in males and 85–95 mm (3.3–3.7 in) in females. Forewing above at most with two blue submarginal spots in cellules 7 and 8; rarely in the female with several yellow ones; the blue (male) or greenish (female) median band is 2–7 mm broad at the hindmargin of the forewing and 4–12 mm in the middle of the hindwing, and is only a little widened posteriorly; the spot in cellule 2 of the hindwing does not completely cover the base of the cellule and the narrow spot in cellule lc does not reach the cell; forewing beneath almost always entirely without submarginal spots. [Nominate] Median band of the forewing above well developed, the spots of cellules 2—4 obliquely cut off distally; the discal spot in cellule 2 of the hindwing is very long and produced farther towards the anal angle than the spot in cellule 1 c.

The median band narrower, but complete; the spot in cellule 2 of the hindwing is shorter and does not reach so far towards the anal angle as the one in 1 c. Larva above green, beneath whitish, with a whitish oblique longitudinal streak at each side on segments 7 and 8 and a girdle of ring-shaped spots on the third segment.
