Ohh Bugs!!!
Many kinds of insects live in different types of water. Some live only in clean water while others live in dirty polluted water!
The different insects that live in streams can tell us how healthy that stream is! Many insects need clear, cool water, lots of oxygen and lots of food to stay alive. BUT some like to live in polluted water and even like to eat dirty smelly sewage! Insects are also food for many other animals like birds and fish!
