Adults are known to nectar from a variety of flowers.
The genus Papilio is Latin for Butterfly. The origin of the species echerioides is currently unknown.
The White-Banded Swallowtails are usually found in thick forested areas but they often visit open areas in search of nectar plants.
Not being extremely strong fliers the adults can usually be found in the vicinity of their host plants. Males patrol for receptive females in the forested areas. Once a female has mated she then searches for a host plant to lay her eggs on. The larvae feed on the host plant until they form their chrysalis.
Information on the number and timing of the broods in the wild is currently unavailable.
The White-Banded Swallowtail, Zoroaster Swallowtail (Papilio zoroastres) and the Jackson’s Swallowtail (Papilio jacksoni) are three different species of butterflies found in Kenya which look almost identical in both the female and male forms.
