Large Cinnamon Sedge

A large, robust caddisfly with broad cinnamon-colored wings found across Europe. Larvae build heavy stone cases in cool upland streams.

💡

Did You Know?

Its heavy stone case protects it from both predators and the strong currents of mountain streams.

Saddle-Case Caddisfly

A small caddisfly whose larvae build distinctive saddle-shaped cases from tiny stones. When it pupates, it cuts the case free from the rock and seals itself inside.

💡

Did You Know?

Saddle-case caddisfly larvae graze algae so efficiently that they can create visible clean patches on otherwise algae-covered stream rocks.
