What is an insect?

Insects are a special group of arthropods. All insects share several, easily-recognizable external characteristics including:

  • Three body segments
    (head, thorax, and abdomen)
  • Three pairs of jointed legs,
    all of which are attached to the thorax
  • Antennae (although there are a few species of insects with no antennae)
  • Wings (though there are some flightless insects)

The figure below demonstrates some of these characteristics of insects.
