How does the beetle's mechanical defense (bite) differ from a true insect sting?

Answer

The bite uses mechanical pressure capable of breaking skin, relying on brute force rather than venom.

Unlike a sting which injects venom, the beetle's bite relies on the mechanical pressure of its powerful jaws, which is strong enough to break the skin and cause bleeding.
