INSECTS

Insects are a class within the arthropods that have a chitinous exoskeleton, a three-part body (head, thorax, and abdomen), three pairs of jointed legs, compound eyes, and two antennae. They are among the most diverse group of animals on the planet and include more than a million described species and represent more than half of all known living organisms. Insects may be found in nearly all environments, although only a small number of species occur in the oceans, a habitat dominated by another arthropod group, the crustaceans.

Ten Facts about Insects

  1. Insects are arthropods, a type of invertebrate, animals that lack a backbone.
  2. Insects are the only invertebrates to have developed flight, and this has played an important part in their success.
  3. Many insects are valuable as predators on the harmful species, and some are important as scavengers and as aerators of the soil.
  4. Insects are of aesthetic importance some insects, such as dragonflies, beetles, and butterflies, are widely thought to be among the most beautiful of all animals.
  5. Insects range in length from the feathery-winged dwarf beetle, which is barely visible to the naked eye at 0.25 mm (0.01 in), to the walkingstick of Southeast Asia, which measures up to 50 cm (20 in) with its legs stretched out.
  6. Insect exoskeletons are highly effective as a body framework, but they have two drawbacks: they cannot grow once they have formed, and like a suit of armor, they become too heavy to move when they reach a certain size.
  7. Insects comprise the most diverse group of animals on the earth, with around 925,000 species described. More than all other animal groups combined.
  8. Insects may be found in nearly all environments on the planet, although only a small number of species have adapted to life in the oceans where crustaceans tend to predominate.
  9. Insects commonly regarded as pests include those that are parasitic (mosquitoes, lice, bedbugs), transmit diseases (mosquitos, flies), damage structures (termites), or destroy agricultural goods (locusts, weevils).
  10. Insects are found throughout the world except near the poles and pervade every habitat except the sea.
