This is a pattern that some crafty fly tier on the Bighorn River? came up with. It works like hotcakes in the spring, especially on tailwaters like the Bighorn. Tie it with a pink, tan, or gray body. Wapsi Sow-Scud Dubbing is the preferred dubbing. Ice dubbing would also make a great version of this fly- try UV Tan, UV Gray, or UV Shrimp Pink.
