Ant Stories By Andrey Pavlov

Some ants of the family Ponerinae have toxic venom and are of medical importance. The species include Paraponera clavata (Tocandira) and Dinoponera spp. (false Tocandiras) of South America and the Myrmecia ants of Australia.
In South Africa, ants are used to help harvest rooibos (Aspalathus linearis), which are small seeds used to make a herbal tea. The plant disperses its seeds widely, making manual collection difficult. Black ants collect and store these and other seeds in their nest, where humans can gather them en masse. Up to half a pound (200 g) of seeds can be collected from one ant-heap.
Although most ants survive attempts by humans to eradicate them, a few are highly endangered. These are mainly island species that have evolved specialized traits and include the critically endangered Sri Lankan relict ant (Aneuretus simoni) and Adetomyrma venatrix of Madagascar.
