Overview

This caddis pupa pattern uses translucent D-Rib for a segmented abdomen over a dubbed underbody, creating a realistic, glossy look. The hallmark Wally Wings—formed from hen saddle or CDC—give the fly a prominent emerging-wing profile. A tungsten bead and soft hackle collar help it sink and pulse naturally in the current.
