Insects may be found in almost all environments, although only a small number of these types of species arise in the oceans.
The adult insects vary in size from a 0.139 mm to a 56.7 centimeter. The heaviest recognized present day insects were the Giant Weta. The biggest known extinct insects are the ancient dragonfly, Meganeura. The relationship of insects evolutionary record to that of other animals is unclear. In the Paleozoic Era, fossilized insects of huge size have been found, including giant dragonflies with wingspans of 55 to 70 cm much larger than any living insect. Many greatly successful insects groups are shown to have coevolved with blossoming plants.
The chief transportation of insects includes walking, flying, and even swimming. Walking as locomotion in insects is one of the most competent forms. Some have even tried to copy it through robotics as a way of locomotion. Insects are the only invertebrates to have evolved flight. Some insects are even able to swim, others being completely aquatic or even skimming on the surface. Insects are mostly lonely, but some are social insects, living together in large well organized colonies and some others taking care of their young. Some common insects include ants, bees, and wasps, which actually benefits humans by making honey.

Insects belong to the Class Insecta. Insects are arthropods, having a three pairs of jointed legs, firm exoskeleton, two antennae, a three part body and mix eyes. They are the most varied among the types of species on the planet. Insects include more than a million species that are previously described. They represent more than half of all known breathing organisms. The number of the insects species is expected at between six and ten million. They represent over 90% of the conflicting life forms.
