 cankerworm
      n : green caterpillar of a geometrid moth; pest of various fruit
          and shade trees

 Cankerworm
    (Heb. yelek), "the licking locust," which licks up the grass of
    the field; probably the locust at a certain stage of its growth,
    just as it emerges from the caterpillar state (Joel 1:4; 2:25).
    The word is rendered "caterpillar" in Ps. 105:34; Jer. 51:14, 17
    (but R.V. "canker-worm"). "It spoileth and fleeth away" (Nah.
    3:16), or as some read the passage, "The cankerworm putteth off
    [i.e., the envelope of its wings], and fleeth away."
