What's the difference between larva and larve?

Larva


Definition:

  • (n.) 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.
  • (n.) The early, immature form of any animal when more or less of a metamorphosis takes place, before the assumption of the mature shape.

  • (19) Statistical analysis has shown the following: a) the growth inhibition, which is especially distinct in autumn-spring generation, takes place in the Ist instar larvae 1.76-2.20 mm long inhabiting the walls of the nasal cavity and concha (their average body length at hatching is 1.08 plus or minus 0.004 mm); the inhibition is associated with interpopulation relations and apparently does not depend on the date of its beginning and can last from 6 to 7 months; c) after the growth resumption the development continues uninterruptedly up to the moulting; the inhibition is also possible at the beginning of the 2nd instar and then the development proceeds without any intervals up to the complete maturation of larvae.
