Insects (Latin: Insecta) - a class of invertebrate arthropod animals. Along with the centipedes belong to the subtype of tracheal. There are about one million species of insects. Have the greatest diversity among all the other animals on Earth, including butterflies, beetles, flies, ants, bees, and others. The science that studies insects is called entomology.
Insects - the largest class of living creatures on Earth, occupying various ecological niches. This happened, presumably because in their development were the priority of the three principles:
* Maximum simplicity of organization;
* The narrow specialization of life;
* The extraordinary fertility.
