Any young insect from the time that it hatches from the egg
   until it becomes a pupa, or chrysalis. During this time it usually
   molts several times, and may change its form or color each time. The
   larvae of many insects are much like the adults in form and habits, but
   have no trace of wings, the rudimentary wings appearing only in the
   pupa stage. In other groups of insects the larvae are totally unlike
   the parents in structure and habits, and are called caterpillars,
   grubs, maggots, etc.
