Caterpillar spiracle, coloured scanning electron micrograph (SEM). This spiracle, or air pore, is part of the caterpillars respiratory system. Air diffuses into the spiracle and circulates the body in a network of tubes called tracheae. Waste gases exit the body through the spiracles. The hairs around it prevent foreign bodies entering the system. Caterpillars are the larval stage of members of the order Lepidoptera. Magnification: x500 when printed at 10 centimetres wide. | |
