Insects breath through holes on their body called spiracles.
They are called spiracles, tiny tubes alongside the insect's body which allow it to receive air. Kind of like gills, but for insects. Good luck!

The way in which insects and fish breathe differs in the process in which each receives oxygen. Insects use a tracheal system to receive oxygen and fish use their gills to filter oxygen out of the water.
Animals that have gills include fish, some amphibians like tadpoles, and certain invertebrates such as mollusks, crustaceans, and some insects in their larval stages. These gills enable these animals to extract oxygen from water for respiration.

Many aquatic insects, like mosquito larvae and water scorpions respire through breathing tubes (or valves). They must get oxygen from the surface to breathe.
