In May 2012, a rare butterfly, the Waterberg Copper (Erikssonia edgei), which was thought to have gone extinct almost 30 years ago, was rediscovered by a lepidopterist, Mark Williams, at Bateleur Nature Reserve north-west of Bela-Bela in the Waterberg district of Limpopo. Thanks to the pristine conditions and favourable habitat, this is currently the butterfly's only known location in the world. It was last seen in the only known colony, west of Modimolle, in the early 1980s.
