The Caterpillar of the large white butterfly.
Caterpillars eat leaves voraciously, grow rapidly, shed their skins generally four or five times, and eventually pupate into an adult form. Caterpillars do not breathe through their mouths. Air enters their bodies through a series of small tubules along the sides of their thorax and abdomen. These tubules are called 'spiracles', and inside the body they connect together into a network of airtubes or 'tracheae'.Photo credit: Sannse
