Larvae feed on the leaves of some species of the genus Rosa, for example Rosa canina, Rosa majalis and Rosa pimpinellifolia.

19-4-2022 MANDINA LODGE, GAMBIA - AFRICAN PIED HORNBILL (Lophoceros fasciatus)
The African pied hornbill (Lophoceros fasciatus) is a bird of the hornbill family, a family of tropical near-passerine birds found in the Old World.
The African pied hornbill is a common resident breeder in much of equatorial Africa, from The Gambia to western Uganda and northern Angola. This is a bird of mainly forest habitats. The female lays up to four white eggs in a tree hole, which is blocked off during incubation with a cement made of mud, droppings and fruit pulp. There is only one narrow aperture, just big enough for the male to transfer food to the mother and the chicks.
