Stonefly

Nemoura

Stoneflies belong to a group of primitive winged insects which undergo an aquatic nymph stage. They are commonly found near streams and rivers with gravelly bottoms. They are harmless, as they do not bite, sting, or transmit diseases. These insects play a significant role in the environment and are indicators of a healthy ecosystem. Stonefly nymphs require cool, highly oxygenated water for survival. Their presence in a stream or river indicates that the water is clean and unpolluted. Both nymphs and adults are important components of the aquatic food chain, serving as a primary food source for fish, amphibians, and birds. Adults are generally weak flyers and have a short lifespan, typically ranging from a few days to a few weeks, during which they focus solely on breeding.
