Spanish Style CDC Dry Fly - Baetis - Fly Tying Materials

Inspired by the legendary silk bodied mayfly patterns tied along Spain's most demanding trout rivers, this Spanish Style Baetis Dry Fly brings together natural materials and precise construction for technical dry fly fishing. Built on a barbless Mustad R50XAP hook with a body of Ephemera silk thread, Datum floss ribbing, Coq de Leon tail, and a natural mallard CDC wing, this pattern sits flush in the film with an unmistakable profile. The Datum floss sighter post keeps it visible in broken water without sacrificing the natural presentation that makes Spanish patterns so effective.
