(Left, to right) Above is a picture of a Stonefly and the Stonefly is a intolerant bug. The next picture is a Water Mite and it is a very intolerant bug.

Intolerant and very Intolerant are sensitive and very sensitive bugs. Intolerant bugs that live in polluted streams don’t do so well. But if you put a very Intolerant bug in a polluted stream will die really fast. That’s also a really good way to tell if your streams polluted or not. If it is there will be a lot of tolerant bugs and barley any Intolerant bugs. And then if you reverse that your stream would be polluted.
