Plecoptera (stoneflies)

Plecoptera, commonly known as stoneflies, are an order of insects characterized by their soft bodies, long antennae, and two pairs of membranous wings that lie flat when at rest. They are aquatic during their nymph stage, living in clean, well-oxygenated streams and lakes, where they play a vital role in the food chain. As adults, they emerge from water to mate and lay eggs, usually near freshwater habitats. Stoneflies are indicators of healthy water quality, as they require high oxygen levels and are sensitive to pollution. Their presence signals a pristine aquatic environment.
