Hubner (1823) established the genus Eronia with the species cleodora. Its distribution is most of Africa. Cleodora possibly after one of the the Thriai nymphs.
Eronia leda was originally Dryas leda Boisduval 1847, but revised to Eronia (Suffert 1904). The Dryads were tree nymphs. Leda of course from Leda and the Swan. Each of her two eggs gave birth to twins: two boys, Castor and Pollux, and two girls Clytemnestra and Helen (of Troy).
Post script: E Leda now Afrodryas leda - the African tree nymph.
