The Peeping Caddis Tungsten Bead Barbless Size 10 represents a caddis larva protruding from its case. The pale larval body creates the familiar 'peeping' profile, while the tungsten bead helps the fly reach the riverbed quickly.
Dead-drift it through runs and glides on a tight-line or indicator setup. Focus on gravelly and stony water where cased caddis are present, keeping the fly close to the bottom. Fish it through likely water and wait for the line to tighten.
