  Insect \In"sect\ ([i^]n"s[e^]kt), n. [F. insecte, L. insectum,
     fr. insectus, p. p. of insecare to cut in. See Section. The
     name was originally given to certain small animals, whose
     bodies appear cut in, or almost divided. Cf. Entomology.]
     1. (Zool.) One of the Insecta; esp., one of the Hexapoda. See
        Insecta.
        [1913 Webster]
  
     Note: The hexapod insects pass through three stages during
           their growth, viz., the larva, pupa, and imago or
           adult, but in some of the orders the larva differs
           little from the imago, except in lacking wings, and the
           active pupa is very much like the larva, except in
           having rudiments of wings. In the higher orders, the
           larva is usually a grub, maggot, or caterpillar,
           totally unlike the adult, while the pupa is very
           different from both larva and imago and is inactive,
           taking no food.
           [1913 Webster]
  
     2. (Zool.) Any air-breathing arthropod, as a spider or
        scorpion.
        [1913 Webster]
  
     3. (Zool.) Any small crustacean. In a wider sense, the word
        is often loosely applied to various small invertebrates.
        [1913 Webster]
  
     4. Fig.: Any small, trivial, or contemptible person or thing.
        --Thomson.
        [1913 Webster]
