The Head

• The head is one of the main three body regions of
  an insect. The head includes the eyes, antennae,
  and mouthparts.

3
Antennae

• The antennae of an insect are used to smell odors
  or to sense touch. Antennae size and shape vary
  from insect to insect.

4
Mouthparts

• Mouthparts are different in each species of
  insect. Some insects, like grasshoppers, have
  chewing mouthparts. Others, like butterflies,
  have sucking mouthparts. The mouthparts determine
  how the insect eats.

5
Thorax

• The Thorax is the middle of the three body
  segments. It is split into three segments. There
  are three pairs of legs (one connected to each
  segment) and one or two pairs of wings.

6
Wings

• Most insects have two pairs of wings, but some,
  like flies, have only one pair. The wings can be
  soft or hard. Sometimes wings have small hairs or
  scales on them.

7
Legs

• Insects have six legs. They have a pair on each
  of the three segments of the thorax. The legs
  themselves are segmented, and usually the last
  segment has a small set of claws. Some insects
  have special legs for jumping.

8
Abdomen

• The abdomen is the last of the three main body
  segments. It consists of eleven segments itself.
  The abdomen contains the external genitalia of
  the insect. In females, these consist of an
  ovipositor.

Conclusion

• There are three main body segments of an insect.
  They are the HEAD, THORAX, and ABDOMEN.
• The HEAD consists of the eyes, antennae, and
  mouthparts.
• The THORAX is three segments and includes the
  wings and six legs.
• The ABDOMEN is eleven segments and includes the
  external genitalia.
