Abstract

Lay SummaryHere, we show that one species of leaf-footed bug can self-amputate an injured limb to reduce the cost of injury. Other benefits of self-amputation include escaping predation and escaping entrapment. By identifying different benefits of this behavior, we stand to gain a more comprehensive understanding of how such an extreme trait evolves.
