The Crane Fly Larvae uses its rear end to breath oxygen not in the water, so it doesn't need to have a high dissolved oxygen level to live. It does need a nice muddy bank to make its burrow in so that it can change into a crane fly before hatching after the winter.
Dobsonfly Larvae (Corydalinae)
Uses its hook-like appendages to grasp on to solid surfaces because it is not a very strong swimmer. It also preys on smaller aquatic insects and its largest predators are fish and frogs. They are sensitive to pollution.
Riffle Beetle (Elmidae)
They like to hang out in fast-moving rivers on stones because they need a lot of oxygen and riffles are where the most dissolved oxygen can be found.
Black Fly Larvae (Simuliidae)
These larvae attach themselves to rocks and can not move until they are fully grown. They require a lot of dissolved oxygen and can not flee from pollution and they are sensitive to it.
Horsehair worm (Nematomorpha)
They knot themselves up because they live in the water and grow to be quite long in length. They are parasitic off of the other macroinvertebrates which require a clean ecosystem to survive so naturally, the horsehair worm is also sensitive to pollution.
Sponge Fly Larvae (Neuroptera)
They mostly stay in their cacoons while in the larvae phase, but need to prey on macroinvertibrates once their manibles break out of their cacoons.
Water Mite (Hydrachna)
Water Mites must live in areas with a lot of plants. These plants are sensitive to pollution, and without them, the water mite could not survive. They are closely related to the spider and have eight legs.
Water Penny (Psephenidae)
These are sensitive to pollution because the pollution causes more algae to grow. Although they eat the algea, if there is too much, it ruins their habitats and they can not survive.
