False-colour scanning electron micrograph of the posterior end of a honeybee,Apis mellifera,showing the bee's needle-like sting. 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 & 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,one producing poison. The tip is armed with backward-sloping barbs,which makes it difficult to remove intact. Magnification: x71 at 35mm size. Original is BW print Z345/134 | |
