Small Amber Spinner

A tiny mayfly whose amber-colored spinners fall to the water in dense clouds. Nymphs live among fine sediments in slow-flowing water.

💡

Did You Know?

Spinner falls can be so dense they coat the water surface like a film, triggering frenzied fish feeding.

Caddisfly

Moth-like adults with hairy wings held tent-like over the body. Aquatic larvae are famous architects that build portable cases from silk, pebbles, sand, leaves, and shells.

Did You Know?

Artist Hubert Duprat gave caddisfly larvae gold flakes, pearls, and precious stones — the larvae incorporated them into their cases, creating tiny jeweled sculptures.
