Blue-Banded Swallowtail | Papilio nireus EGGS
Papilio nireus, commonly known as the Blue-banded Swallowtail, is a stunning butterfly species in the family Papilionidae (Swallowtails). It is widely distributed across sub-Saharan Africa, inhabiting forests, woodlands, and savannas. This butterfly is admired for its striking coloration and graceful flight.
The wings of Papilio nireus are jet black with vibrant turquoise or blue-green bands that run diagonally across the forewings and continue as spots on the hindwings. The hindwings have a scalloped edge and may feature subtle tails, a characteristic trait of many swallowtails. The vivid green bands provide a striking contrast, making this butterfly a visual standout in its natural habitat.
The caterpillars of Papilio nireus are green with white or yellowish markings, helping them blend into the foliage of their host plants, primarily trees and shrubs from the Rutaceae family, such as citrus plants. Females lay their eggs singly on the leaves of these plants, which serve as the sole food source for the larvae.
Papilio nireus exhibits swift and strong flight, often seen flitting through forest clearings or feeding on flower nectar. Its ecological role as a pollinator and its exquisite beauty make it a valuable species in African ecosystems, as well as a favorite among butterfly enthusiasts and conservationists.
