Ankle dancing rattles are made from a coccon of particular moth species which attaches itself to a tree. After harvesting they are filled with small pebbles and sewn to a piece of isikhumba hide. Tied to ankles and wrists, they are used by sangoma diviners and their initiates when dancing to drumming, song and clapping. During these performances participants attain a state of trance which enables them to divine lost possessions, missing relatives, livestock, and herbs for healing various ailments.
