Bee sting. Coloured scanning electron micrograph (SEM) of the end of the needle-like sting of a honeybee, tipped with blood. The sting is a modification of the female ovipositor, or egg- laying apparatus. It is no longer used to lay eggs, but instead serves as a weapon of defence. The sting consists of moveable chitinous elements, into which the ducts of two glands open. When a bee stings, the contents of the alkaline gland are mixed with the contents of the acid gland producing poison. The tip is armed with backward- sloping barbs, which makes it difficult to remove intact. The action of stinging kills the bee. Magnification unknown.
