How to Rig It

Fish it alone during spinner falls when trout are sipping spent mayflies calmly.

How to Present It

Cast above the rise and let it drift absolutely flat with no drag.

Why It Works

Spent-wing Callibaetis are helpless on the water and trout often key on them selectively.

History

Callibaetis spinner patterns are essential on western lakes and spring creeks with steady mayfly cycles.

Pro Tip

If trout are refusing upright duns late in the hatch, switch to the spinner immediately.
