Stonefly

Near clean, well-oxygenated freshwater streams and rivers. Nymphs live under submerged rocks.

Nymphs are either carnivorous (eating other small aquatic insects) or detritivorous. Adults rarely eat or consume algae/lichen.

Adults are relatively short-lived and weak fliers, often found resting on foliage or structures near water. They have a hemimetabolous (incomplete) life cycle.

Harmless to humans. They are vital indicators of high water quality and serve as a primary food source for trout and other wildlife.
