This is an adaptation of the late Ernest Herbert “Polly” Rosborough's Black Drake Swimmer Nymph/Emerger pattern. I tie this pattern in the following colors, black (as shown), olive and dark brown.
The black pattern in sizes 14 & 16 has been the most successful pattern for me.
Swimmer nymphs are best suited for ponds, lakes, and to the slower flows of spring creeks and tailwaters.
