There are many kinds of insects.  They may all look different, but they are alike.  They are alike in three ways.

  • six legs
  • three main body sections (head, thorax, and abdomen)
  • hard skeleton

One way all insects are alike is that they have six legs.  Three legs on each side of the body.  The legs are attached to the thorax.  The thorax is the middle part of an insect's body.  Many insects have wings that are attached to the thorax.

Behind the thorax is the abdomen.  It is usually the largest part of an insect.

In front of the thorax is the head.  Eyes and a mouth are located in the head.  Antennae or feelers are also found on the head.  These are used to smell, feel, and taste things.

Insects have a skeleton too!  Their skeleton is on the outside of their bodies.  It is called an exoskeleton.  Your skeleton is found inside your body, and it is made of bones.  An insect's skeleton is the hardest part of its body.  It is made of a material called chitin.
