Stoneflies spend most of their lives as larvae in the water, crawling along the bottom of streams and rivers, and clinging to the underside of rocks and woody debris. Some are predators (they eat other bugs), while others eat plants and algae or decaying organic matter (plant bits).

Where can you find stoneflies?

Stoneflies, as you can guess, live in habitats with plenty of stones. They prefer fast-moving, clear streams with a bot- tom of rocks and stones. Small mountain brooks and large streams in wooded areas usually have plenty of this type of habitat, and often many stoneflies.

Where are stoneflies native to?

Stoneflies are found worldwide, except Antarctica. Stoneflies are believed to be one of the most primitive groups of Neoptera, with close relatives identified from the Carboniferous and Lower Permian geological periods, while true stoneflies are known from fossils only a bit younger.
