Bee sting. Coloured scanning electron micrograph of the posterior end of a honeybee Apis mellifera showing the bee's sting (needlelike). The sting is a modification of the female ovipositor,or egg- laying apparatus. The ovipositor is no longer used to lay eggs,but instead serves as a weapon of defense and as a means of paralysing the bee's prey by injection. Only females sting. The sting consists of moveable chitinous elements,into which the ducts of two glands open (red,at bottom): one producing poison. The barbed sting is found only on worker bees.
