stoneflies
Aquatic nymph adults
Stoneflies are aquatic insects whose nymphs live in clean, cold streams and rivers, making them indicators of water quality.
Adults have two pairs of wings that fold flat over their backs.
Fly fishers prize stonefly imitations because trout feed heavily on them: The hatch brought stoneflies to the surface and the fish went crazy.
