Weevil \Wee"vil\, n. [OE. wivel, wevil, AS. wifel, wibil; akin
   to OD. wevel, OHG. wibil, wibel, G. wiebel, wibel, and
   probably to Lith. vabalas beetle, and E. weave. See {Weave}.]
   (Zool.)
   Any one of numerous species of snout beetles, or
   Rhynchophora, in which the head is elongated and usually
   curved downward. Many of the species are very injurious to
   cultivated plants. The larvae of some of the species live in
   nuts, fruit, and grain by eating out the interior, as the
   plum weevil, or curculio, the nut weevils, and the grain
   weevil (see under {Plum}, {Nut}, and {Grain}). The larvae of
   other species bore under the bark and into the pith of trees
   and various other plants, as the pine weevils (see under
   {Pine}). See also {Pea weevil}, {Rice weevil}, {Seed weevil},
   under {Pea}, {Rice}, and {Seed}.
