   Tent caterpillar (Zool.), any one of several species of
      gregarious caterpillars which construct on trees large
      silken webs into which they retreat when at rest. Some of
      the species are very destructive to fruit trees. The most
      common American species is the larva of a bombycid moth
      (Clisiocampa Americana). Called also {lackery
      caterpillar}, and webworm.
