Overview

This emerger features a “batwing” of CDC folded over the top of the thorax to imitate a trapped dun. The body is slender and dubbed, with sparse tails and sometimes a trailing shuck. Tie the CDC wing in forward, then fold it back over the top and secure behind the hook eye. Use a fine thread and keep proportions delicate.
