Why do earwigs have pincers?

Answer: Defense and catching prey

Digging underground tunnels — Wrong. Earwigs do live under debris and in crevices, but they don't dig with their pincers. The pincers are for grasping and defense.

Defense and catching prey ✓ — Correct! Earwig pincers (called cerci) serve multiple purposes: catching and holding small insects for food, defense against predators, and males use them in wrestling matches over mates. They look intimidating but rarely pinch humans hard enough to hurt—it's mostly bluff!

Climbing up smooth surfaces — Wrong. Pincers aren't climbing tools. Earwigs use their legs to climb. The pincers are primarily for grasping prey and defensive displays.
