Honey bee sting. Coloured scanning electron micrograph (SEM) of the sting of a honey bee (Apis mellifera). Honey bees live in a colonial nest. The worker bees use their stings to defend the nest, pumping a venom into their enemy which causes a painful inflammatory reaction. When a vertebrate is attacked, the sting detaches from the bee's abdomen and embeds in the skin, ensuring that the venom reaches the most sensitive tissues. A chemical signal is also released, alerting other bees to a vulnerable area. The backward- sloping barbs at the tip of the sting ensure that it detaches from the bee's abdomen. The bee then dies. Magnification x158 at 6x7cm size.
