Trachea

The trachea are part of the respiratory system of insects. Air enters the insect's body through the spiracle and enters the trachea. The trachea are tubes that are strengthened by rings of cuticle. From the trachea the air moves into smaller tubes called tracheoles that spread throughout the body of the insect and allow oxygen to be delivered to the various parts of the body.
