What are the pinchers at the end of an earwig's abdomen called?

The pinchers at the end of an earwig's abdomen are called cerci. Cerci are specialized appendages that can serve various functions depending on the species. In earwigs, they are often used for defense as well as in mating behavior. The cerci can help the earwig grasp and hold onto surfaces or other organisms, which is particularly helpful during aggressive encounters or courtship displays.

Understanding this distinction is important in recognizing the anatomy and behavior of insects. While the other terms like claspers, spines, and mandibles refer to different structures with specific functions in various organisms, cerci are uniquely adapted for certain activities within the context of earwigs, making them the correct term for this specific anatomical feature.
