They use their powerful mandibles to crush and chew their prey. Some stonefly species are also known to feed on algae and detritus.
Stoneflies typically hunt by crawling on the bottom of streams and rivers, searching for prey. They may also lie in wait for prey to come by, or they may actively chase down their quarry. When they find prey, they will quickly lunge at it and grab it with their mandibles.
Stoneflies are an important part of the aquatic ecosystem, as they help to control the populations of other invertebrates. They are also a food source for fish and other aquatic predators.
