What's the difference between insect and metathorax?
Insect
Definition:
(n.) One of the Insecta; esp., one of the Hexapoda. See Insecta.

(n.) Fig.: Any small, trivial, or contemptible person or thing.
(a.) Of or pertaining to an insect or insects.
(a.) Like an insect; small; mean; ephemeral.

Metathorax
Definition:
(n.) The last or posterior segment of the thorax in insects. See Illust. of Coleoptera.
Example Sentences:
(1) A chordotonal organ occurring in the posterior metathorax of an atympanate moth, Actias luna (L.) (Bombycoidea: Saturniidae), appears to be homologous to the tympanal organ of the noctuoid moth.
