3. Papilio nireus nireus Linnaeus, 1758

WL: 55mm. This is a common and widespread forest species in Guinea-Bissau. Females are harder to observe, as they usually occur in the vicinity of host-plants within forest habitats. It is similar to P. sosia, but possesses a narrower green band on the forewing and hindwing recto. The nominate subspecies is distributed throughout sub- Saharan West and Central Africa, from Senegal to Angola and Zambia; the East African subspecies is P. n. lyaeus. The caterpillars also feed on Rutaceae .
