Very few other animals can fly. Flying helps insects escape predators and move from place to place, thus broadening the space they can inhabit. However, not all insects have wings. Survival of the Fittest Insects can be considered the most dominant life form on earth. Special body parts enable insects to survive in environments normally considered to harsh for survival.
