Longhorn beetles have very powerful chewing mouthparts that can bite through very hard wood, so they do bite people, and especially if you grab them the wrong way you may get bitten. It is said that the adult Titanus giganteus can reach 16.7 cm in body length, and if its antennae are included it can reach 21 cm in length. It has a hard exoskeleton and powerful mandibles, and the mandibles can bite through a pencil or cut into human skin.
