Century Dictionary and Cyclopedia
    • n ovipositor The ovipositing organ with which many (especially hymenopterous, orthopterous, coleopterous, and dipterous) insects are provided, and by means of which they place their eggs in a position suitable for development. It forms the end of the abdomen, several of the rings or somites of which are specially modified for this purpose. It normally or usually consists of three pairs of rhabdites, the outer two pairs of which incase or sheathe the inner pair, and form an extensile tube, of very variable size and shape in different insects. It is sometimes longer than the body of the insect. In the terebrant hymenopters the ovipositor forms a saw or an auger (serra or terebra). In the aculeate hymenopters, as bees and wasps, the ovipositor is the sting or aculeus. In orthopters it is often conspicuous, as seen in the cut. Also called oviscapt. See also cuts under canker-worm and Cecidomyia.
