Overview

A minimalist midge pupa pattern tied with thread, fine wire ribbing, and a small bead for subtle weight. Often featuring a black or red body with silver or copper ribbing, this fly is all about slim profile and segmentation. It's a quick tie and excels during winter or low-hatch periods when trout are focused on tiny midges just below the surface.
