1.
(Zoöl.) One of the Insecta; esp., one of the Hexapoda. See Insecta.
&fist; 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.
2. (Zoöl.) Any air-breathing arthropod, as a spider or scorpion.
3.
(Zoöl.) Any small crustacean. In a wider sense, the word is often
loosely applied to various small
invertebrates.
4. Fig.: Any small, trivial, or contemptible person or thing. Thomson.
