Nephele hespera is a species of moth belonging to the family Sphingidae, commonly known as hawk-moths or sphinx moths. It is one of several species within the genus Nephele, which are generally characterized by their robust bodies, narrow wings, and rapid, powerful flight.
Taxonomy
Nephele hespera belongs to the order Lepidoptera (moths and butterflies), family Sphingidae (hawk-moths), and genus Nephele. Within Sphingidae, it is placed in the subfamily Sphinginae. The specific epithet "hespera" is derived from Greek, meaning "western" or "evening," a common descriptor in taxonomy that might refer to its geographical distribution or its nocturnal activity.Description
Nephele hespera is a medium-sized hawk-moth with a typical forewing length ranging from approximately 38 to 40 millimeters. The forewings are generally shades of brown or grey-brown, often featuring a distinctive large, roughly triangular or somewhat reniform (kidney-shaped) pale discal spot, which can be white, cream, or yellowish. This pale spot is a key diagnostic feature for the species. The hindwings are typically darker brown or greyish brown towards the margin, with a paler, often whitish or yellowish, basal area. The body is stout and covered in scales matching the wing coloration.Distribution and Habitat
This species is primarily found in East Africa and extends into parts of Central and Southern Africa. Its known distribution includes countries such as Kenya, Tanzania, Uganda, Rwanda, Burundi, Democratic Republic of Congo, Zambia, Malawi, and Mozambique. It inhabits various habitats, including woodlands, savannas, and sometimes forested areas, particularly where its larval host plants are present.Ecology and Life Cycle
Like most hawk-moths, Nephele hespera is nocturnal, meaning the adult moths are active and fly at dusk and throughout the night. Adult moths are known to feed on nectar from various flowering plants, playing a role in pollination.The larvae (caterpillars) of Nephele hespera are known to feed on plants belonging to the genus Combretum (family Combretaceae). Combretum species are widespread in the same African regions as the moth, providing a readily available food source for the caterpillars. The full life cycle, including details of the egg and pupal stages, follows the typical lepidopteran pattern.
