SPRINGTAIL , the See also:common name of a See also:group of small See also:insects, so named from the presence of a pair of tail-like appendages at the end of the See also:abdomen, which acts as a See also:spring. When the See also:insect is undisturbed these appendages are turned forwards and held in position by a catch beneath the abdomen; but in See also:case of alarm they are kicked forcibly downwards and back-wards, jerking the See also:body into the See also:air. This See also:action may be rapidly repeated until a See also:place of safety is reached. These insects usually live under fallen leaves, stones or the bark of trees, and sometimes occur in such quantities as to resemble patches of See also:powder or dust. One See also:species (Podura aquatica) may be seen floating in this way in masses upon the See also:surface of See also:standing See also:water. Another (Achorutes socialis) may sometimes be found in abundance in the See also:snow. Zoologically the springtails belong to the sub-See also:order Collembola of the order See also:Aptera (q.v.).
