The CDC Transitional Dun occupies the narrow space between emerger and adult -- neither fully hatched nor still emerging, but caught in the vulnerable moment of transformation that trout find most appealing. The CDC wings provide both floatation and a realistic wing silhouette, while the trailing shuck anchors the rear of the fly in the film. It is a fly designed for the angler who has watched too many trout eat something they could not identify, right at the surface, and decided to tie a pattern that exists in both worlds at once. The trout approve. They always approve of vulnerability.

Trout eat more insects during emergence than at any other stage. Emerger patterns — flies that imitate the critical moment when a nymph transforms into an adult in the surface film — are the most consistently effective dry flies in fly fishing. Here is the science and the technique behind fishing the in-between.
