Springtail \Spring"tail`\, n. (Zo["o]l.)
   Any one of numerous species of small apterous insects
   belonging to the order {Thysanura}. They have two elastic
   caudal stylets which can be bent under the abdomen and then
   suddenly extended like a spring, thus enabling them to leap
   to a considerable distance. See {Collembola}, and {Podura}.
