How to Rig It

Single wet, or trail behind an Elk Hair Caddis as a dry-dropper.

How to Present It

Swing through riffles and tailouts; let it sink and rise on tension.

Why It Works

Egg-laying caddis dive and trout hammer them — but most anglers fish only dries during a caddis hatch and miss this behavior.

History

Gary LaFontaine documented the diving caddis behavior in 'Caddisflies' (1981); his sparkle pupa and diving caddis patterns transformed caddis fishing.

Pro Tip

Right at last light during caddis season, swing this through soft water. It's the highest-percentage fly nobody fishes.
