The Class Insecta
Insects, Figure 21, are the largest group, with probably over one million identified and named species (and undoubtedly a greater number as yet unknown to us).
There are about 26 orders in the Class Insecta and you will find species everywhere. There may be tiny little fleas and there may be monster mosquitoes in the jungle.
insect - an animal of class Hexapoda (or Insecta) of subphylum Uniramia of phylum Arthropoda.
In Linnaeus' original scheme, the animals were one of three kingdoms, divided into the classes of Vermes, Insecta, Pisces, Amphibia, Aves, and Mammalia.

mandibles Third pair of appendages from the anterior in Crustacea; second pair in Insecta; primarily function in feeding; derived from appendages on primitive fourth (first postoral) somite.
testicular cyst [Gr. cysto - a sac or bladder]. Found in the testicular lobes of grasshoppers (Insecta, Orthoptera), a membrane bound structure containing a group of germ cells that are all at the same stage of spermatogenesis.
Class: A category of the classification scheme of living organisms ranking below a phylum and above an order (e.g., Insecta).
