How to Rig It
Anchor fly under an indicator; pair with a smaller mayfly nymph.
How to Present It
Dead-drift on the bottom — cased caddis don't move much, so let it tumble.
Why It Works
Cased caddis are present year-round and trout eat the whole case, gravel and all. The peeking head is the strike trigger.
History
An old soft-hackle and Czech-nymph derivative — modern tungsten versions sink fast and stay in the strike zone.
Pro Tip
Fish it deep and slow in winter. Cased caddis are one of the only reliable food sources when nothing else is moving.
