What are the characteristics of the insects that make them successful?
Insects possess an amazing diversity in size, form, and behavior. It is believed that insects are so successful because they have a protective shell or exoskeleton, they are small, and they can fly. Their small size and ability to fly permits escape from enemies and dispersal to new environments.
