Detailed explanation-1: -Most Insects have what is called Bilateral Symmetry. This means that if you had to draw a line through the middle of their bodies you will see that both sides are the same.

Detailed explanation-2: -Animals with bilateral symmetry have a “head” and “tail” (anterior vs. posterior), front and back (dorsal vs. ventral), and right and left sides.

Detailed explanation-3: -Examples of animals that possess bilateral symmetry are: flatworms, common worms ("ribbon worms"), clams, snails, octopuses, crustaceans, insects, spiders, brachiopods, sea stars, sea urchins, and vertebrates. The symmetry of an animal generally fits its lifestyle.
