Zuträge zur Sammlung exotischer Schmettlinge [sic] 1: 13 ([3] + 4-6 + [7] + 8- 32 + [33] - [40] pp.). Augsburg. [7:-:8]. Type-species: Leptosia chlorographa Hübner, by subsequent designation (Scudder, 1875. Proceedings of the American Academy of Arts and Sciences 10: 204 (91-293). [extralimital]. = Nychitona Butler, 1870. Cistula Entomologica 1: 34, 41 (33-58). Type-species: Papilio dorothea Fabricius, by original designation.

The genus Leptosia belongs to the Family Pieridae Swainson, 1820; Subfamily Pierinae Swainson, 1820; Tribe Leptosiaini Braby, 2014. There are no other genera in the Tribe Leptosiaini in the Afrotropical Region. Leptosia (Wood Whites) is an essentially Afrotropical genus of nine species. Seven species are Afrotropical and two are found extralimitally – L. nina (India to Australia) and L. lignea (Sulawesi). The genus was revised by Bernardi in a series of publications (1952, 1959, 1964, 1966). *Leptosia alcesta (Stoll, [1782])# African Wood White 1 African Wood White (Leptosia alcesta), Burman Bush, Durban.

Distribution: Senegal, Gambia, Guinea-Bissau, Guinea (Bacelar, 1949), Liberia, Ivory Coast, Ghana, Togo, Benin (Fermon et al., 2002), Nigeria, Cameroon, Equatorial Guinea, Gabon, Congo, Central African Republic, Angola, Democratic Republic of Congo, Sudan, Uganda, Ethiopia, Uganda, Kenya, Tanzania, Malawi, Zambia, Mozambique, Zimbabwe, South Africa, Swaziland, Madagascar. 2 Habitat: Forest and heavy woodland (savanna), especially along river courses. Also in disturbed areas in the forest zone (Larsen, 2005a). In Tanzania ssp. inalcesta occurs from sea-level to 1 850 m (Kielland, 1990d). In Madagascar in forest (Lees et al., 2003). Habits: A very common and ubiquitous forest butterfly (Larsen, 2005a). Both sexes keep to the forest understorey where they fly low down, in the shade, with a very weak, bouncing flight. They have been likened, when in flight, to floating pieces of tissue paper. Both sexes feed from small flowers in the forest undergrowth (Pringle et al., 1994). Larsen (1984; 1991; 2005a) recounts that in Nigeria he once saw a specimen settle on water to drink, being supported by surface tension alone, and using its closed wings as a ‘sail’. Males do not normally mud-puddle (Larsen, 1984). They are on the wing from early morning, often at first light (Larsen, 2005a). Flight period: All year but more plentiful in late summer and autumn (Pringle et al., 1994). Early stages: Clark & Dickson, 1967: 38. [Described from material from Umhlanga Rocks, KwaZulu-Natal]. Egg. Laid singly on young shoots; pure white; 1.5 mm high by 0.4 mm in diameter; 10 longitudinal ribs, 6 of which reach the micropyle; ribs are cross-braced by 28-30 fine ribs; eclosion occurs after 4-6 days. Larva. Exits the egg near the top and consumes the discarded shell. On hatching is 1.5 mm long and transparent water- white, the transparency, until it feeds making it difficult to see. Feeds on the edge of a leaf and grows to 3 mm in 6 days. Second instar larva greenish above and whitish below. Selects a resting place from which it ventures forth to feed. Grows to 6 mm in 3 days. Third instar larva green and shows the same habits as the previous instar. Grows to 8 mm in 3 days. Fourth instar larva green but more setose than previous instar. Grows to 12.5 mm in 3 days. Fifth (final) instar larva slightly darker green with faint whitish sub-spiracular stripe. Grows to 22 mm (male) and 23 mm (female) in 10 days. Pupa. Length 15.5-16 mm and pale green. Secured to a twig by cremastral hooks and supported by a girdle. Pupal period about 10 days. There is a succession of broods throughout the year.
