Overview

The Biot Midge Pupa is a sleek, realistic pattern that uses a single goose biot for a segmented body and a sparse thorax of dubbing or thread. A small bead helps it sink quickly, and the slim profile makes it ideal for targeting selective trout feeding on midges. It's a great choice for tailwaters and spring creeks, especially during winter and early spring hatches.
