Nymph
Cased Caddis Larva
The river's 'stick fly'
Trout · GraylingDeep
Trout eat cased caddis case and all; a heavy, shaggy dressing rolled along the bottom — the river 'stick fly'.
Fish this when
In cold, low, clear water through winter and early spring, rolled slowly along the streambed when almost nothing else is moving.
Why it works
Trout swallow cased caddis whole, case included, so the bulky shaggy silhouette reads as an easy, low-risk mouthful rather than something needing split-second recognition.
