📖 Overview

Adults occur in water bodies on low-lying plains, with little current; in water courses at high altitudes and in springs and associated wetlands . Most frequently found in upper, cooler stretches of streams, with current and stone bottom. They feed mainly on benthic macro-invertebrates, especially insect larvae. Spawning occurs on vegetation and under stones . Threatened by water abstraction, pollution, and habitat destruction .
