Key to the adult Amerila species of southern Africa


This key is based on the descriptions in Häuser & Boppré's paper (see references below). Southern Africa in this key covers South Africa, Swaziland, Lesotho, Namibia, Botswana, Zimbabwe, Mozambique, Angola, Zambia and Malawi.

Distribution data is based on what H&B included from specimens only - therefore distributions are probably wider for most species than stated.

All photos included here are subject to ID confirmation!!!

Thank you, Sam :-)

I will improve it as we get more data on iNat (and I need to fix some of the formatting also).

Onwards!
