Description
Bee sting. Coloured scanning electron micrograph (SEM) of the barbed tip of a bee sting. The sting is armed with backward sloping barbs which makes it difficult to remove once it is embedded in skin. The sting of the honeybee Apis mellifera, was originally an egg-laying organ that evolved into a weapon of defence. It consists of moveable chitinous elements into which the ducts of two glands open, one gland producing a poison which is injected when the sting penetrates. Magnification: x510 at 6x4.5cm size.
