The name insect is derived from the Latin "insectum" meaning cut into sections i.e. their bodies are segmented. The insects (class insecta) are the most numorous and diverse members of the phylum group Arthropoda, comprising of one million known species and possibly millions more are yet to be discovered.


Other members of the Arthropoda are the Arachnida (spiders, scorpions and mites), Crustacea (crabs, lobster and woodlice), Chilopeda (centipeds) and Diplopoda (millipedes). All arthropods have an outer shell, call and exoskeleton made of chitin often toughened with a protein called sclerotin, and varying numbers of jointed legs.
