Insects are invertebrates that are taxonomically referred to as the class Insecta.
They are the most numerous and most widespread terrestrial taxon within the phylum Arthropoda.
Insects are the most diverse group of animals on the earth.
With around 925,000 species described—more than all other animal groups combined.
Insects may be found in nearly all environments on the planet, although only a small number of species have adapted to life in the oceans where crustaceans tend to predominate.
