Is a praying mantis poisonous and if so what does it sting and how does it inject its poison?

Praying mantises are not poisonous; they lack venom and do not sting. Instead, they are predatory insects that capture and consume their prey using their strong forelegs. While they can deliver a painful bite if threatened, it is not toxic and poses no danger to humans. Their primary defense mechanisms include camouflage and aggressive displays rather than venomous attacks.
