So this fly is relatively easy to tie, except for splitting the thread. You really need to use a thread like UTC Ultra Thread which is very flat and splits easily. These flies dont float quite as well as some other CDC flies out there, but they float well enough, and are perfect for a hopper dropper, or larger (better floating) fly as the lead. Its a very effective fly for those trout looking to feast on smaller midges and baetis emerging.
As always here is a list of materials used on this fly.
Hook: TMC 100bl in size 16
Thread: UTC Ultra Thread 70 in brown
Body: Turkey Biot in Olive
Hot Spot: 2mm Fly Foam in Red
Wing: CDC in natural dun
Cement: Hard as Hull head cement
