How to Rig It

Fish alone, under a small dry, or on a short dropper during active caddis rises.

How to Present It

Let it drift low and natural at the film where caddis are struggling to emerge.

Why It Works

The subtle wing and bright shuck give trout a clear vulnerable target during caddis activity.

History

The Iris Caddis became a guide favorite on rivers where fish repeatedly refused standard adult patterns.

Pro Tip

Fish it before the main adult rise fully starts—often the emerger phase is when trout feed most confidently.

Frequently Asked Questions

When should I fish an Iris Caddis?+

Fish it during caddis hatches when trout are feeding on insects in the emergence stage rather than fully formed adults.
