How to Rig It

Single fly on a downstream swing, or as a dropper 18" off an Elk Hair Caddis.

How to Present It

Dead-drift through the run, then let it swing up to the surface at the end — the rise mimics a real caddis pupa swimming to hatch. Aggressive grabs.

Why It Works

Gary LaFontaine's bubble-shrouded design replicates the gas envelope a real caddis pupa carries to the surface. When trout are slashing at emergers and ignoring dries, this is the answer.

History

Designed by Gary LaFontaine in his landmark 1981 book Caddisflies after years of underwater observation. Revolutionized how anglers fish caddis hatches.

Pro Tip

Greased Antron shroud > unfloated. A dab of floatant on the bubble keeps it suspended just under the film where caddis emerge.
