Insecta is a class of invertebrate animals with segmented bodies, jointed legs, and external skeletons. They have three main body parts: head, thorax, and abdomen. Insects have two antennae, compound eyes, and three pairs of legs. They can be found in almost any habitat, from deserts to rainforests, and can live for a few weeks to several years. The current population of Insecta is estimated to be around 10 quintillion individuals.
Name Origin: Insecta is a taxonomic class of invertebrates within the arthropod phylum. The name Insecta is derived from the Latin word insectum, meaning "with a notched or divided body", which itself is derived from the neuter singular perfect passive participle of the verb insectare, meaning "to cut into, to cut up, to divide in sections".
