Stonefly

Nymphs live in clean, well-oxygenated freshwater, typically under rocks or debris in streams and rivers. Adults are often found near these aquatic environments.

Nymphs are primarily herbivores (feeding on algae and detritus) or predators (feeding on smaller aquatic insects). Adult stoneflies generally do not feed or feed on algae/lichens.

Nymphs are aquatic and undergo incomplete metamorphosis, shedding their exoskeleton multiple times. Adults are short-lived, often existing only for a few days to a few weeks, primarily for reproduction. They are typically weak fliers and nocturnal.

Stoneflies are important bioindicators of water quality, as their presence indicates clean, unpolluted water. They are a significant food source for fish and other aquatic organisms. There are no known risks to humans.
