[6] Pain is a signal of damage in the body, but molecules that produce pain and those that are toxic, and actively cause damage, are not the same.
Scorpion stinger. In all stinging Hymenoptera the sting is a modified ovipositor. [5] Unlike most other stings, honey bee workers' stings are strongly barbed and lodge in the flesh of mammals upon use, tearing free from the honey bee's body, killing the bee within minutes. [2]

The body of a scorpion is divided into two parts or tagmata: the cephalothorax or prosoma, and the abdomen or opisthosoma.
