Entomologist Caroline Chaboo in Namibia

Caroline Chaboo, entomology curator, studies the evolution of leaf beetles in Namibia. The San Bushmen, drawing on cultural hunting knowledge thousands of years old, apply poison made from these beetles to arrows used in hunting. Scientists know the beetles as Diamphidia locusta. The San refer to them as “kua,” pronounced with a tongue click followed by “eww uhh.”
