Insects are generally terrestrial as very few insects have invaded the sea. The insects pre-empt every space on this world but for the deep oceans. Even in the frozen extremes of the Arctic and Antartica you will see some insects alive and active during the warmer months. Their ability to metamorphose, or change form, allows them to persist against extremes in climate and environment. Their fragile forms strive also in sheer numbers, where one female may produce thousands of eggs, allowing armies to capture Earth.
Insects are ubiquitous, they are everywhere.
Beneath your feet, and in the air, you will find them. In and around plants and all animals, live Insects. An insect is an air breathing animal with a hard jointed exoskeleton. Adult insects have a body divided into three parts, the head with one pair of antennae, the thorax which carries three pairs of legs and usually two pairs of wings, and the abdomen which contains the excretory system and reproductive organs. All living things are divided into a series of categories depending on how closely related they are.
