Giant stoneflies
Scientific name: Pteronarcyidae
Description
Contrary to what one might expect from their formidable name, Pteronarcyidae are gentle giants. These creatures play a pivotal role in aquatic ecosystems, primarily as indicators of water quality. Their presence signals a healthy stream, free of pollution. Interestingly, despite their large size, they are not predatory; they feed mainly on decaying plant matter. The nymphs are aquatic and spend one to three years in water before they emerge as adults. This lifecycle intricately ties them to their freshwater habitats, showcasing the delicate balance within ecosystems where such species thrive.
