Wasp sting. Coloured scanning electron micrograph (SEM) of the sting of the common wasp (Vespula vulgaris). The sting is a modification of the female ovipositor,or egg-laying organ. It is no longer used to lay eggs,but instead serves as a weapon of defence and attack. The sting consists of a lancet (red),with a venom sac at it base and attached muscles. When not in use the sting is encased in the abdomen (bottom). Magnification: x50 when printed at 10 centimetres wide | |
