How do tracheae facilitate gas exchange
WebEven aquatic insects use a tracheal system for gas exchange. Some, like mosquito larvae ("wigglers"), get their air by poking a breathing tube — connected to their tracheal system — through the water surface. Some insects that can submerge for long periods carry a bubble of air with them from which they breathe.
