What is an Insect?
Definition of INSECT
1: any of numerous small invertebrate animals (as spiders or centipedes) that are more or less obviously segmented —not used technically
2: any of a class (Insecta) of arthropods (as bugs or bees) with well-defined head, thorax, and abdomen, only three pairs of legs, and typically one or two pairs of wings
Insects are the most numerous of the animal kingdom, the number of species is estimated to be around one million species worldwide and representing over 90% of all species on earth.
Insects have an exoskeleton, a three part body-head, thorax and the abdomen, three pairs of jointed legs, compound eyes and one pair of antennae, and they can be found in almost all environments.
