Elymniopsis
Elymniopsis is a genus of butterflies in the Nymphalidae family. It contains only one species, the African Palmfly (Elymniopsis bammakoo). It is found in Senegal, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Nigeria, Cameroon, Gabon, the Republic of Congo, the Central African Republic, Angola, the Democratic Republic of Congo, Uganda and Tanzania. The habitat consists of forests.
Adults appear similar to Acraea poggei in flight. The white form of bammakoo mimics the female of Papilio cynorta. Adults are attracted to fermented bananas and have also been recorded imbibing sap from wounds in trees.
The larvae feed on Elaeis guineensis, Phoenix reclinata, and Raphia hookeri.
