Charaxes eupale latimargo (female)
 
Charaxes eupale and the near identical species subornatus are both distributed across the African forest zone from Senegal to western Tanzania. The green colouration of their wings, antennae and proboscises are produced by pigments - in most other green butterflies these colours are produced structurally by light refracting from microscopic ridges on the surface of the scales, or from a lattice within them. Charaxes eupale, the common green charaxes, is a butterfly in the family Nymphalidae. It is found in Senegal, Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Nigeria, Cameroon, Gabon, the Republic of the Congo, the Central African Republic, Angola, Zambia, the Democratic Republic of the Congo, Uganda, Sudan, Rwanda, Kenya, Tanzania and Malawi. The habitat consists of lowland evergreen forests.
The larvae feed on Scutia myrtina, Albizia gummifera, Albizia zygia, Albizia adianthifolia and Cathormion species.
The green colouration is produced by pigments as opposed to being produced structurally, which is common in most green butterflies.
