Ventilation of Tracheal System - Diffusion

Gaseous exchange due to diffusion generally takes care of the oxygen needs of most small insects. Similarly fairly large but inactive insects (e.g., some large caterpillars) do not actively ventilate the system. Diffusion alone is adequate provided the spiracles are kept open permanently. The same process accounts for elimination of carbon dioxide.
