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. (Zo["o]l.) 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. (Zo["o]l.) Any air-breathing arthropod, as a spider or scorpion. [1913 Webster]

3. (Zo["o]l.) 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]

{Insect powder},a powder used for the extermination of insects; esp., the powdered flowers of certain species of {Pyrethrum}, a genus now merged in {Chrysanthemum}. Called also {Persian powder}. [1913 Webster]
