I have highlighted this wonderful lake pattern before. It is easy to tie and very productive in brown or olive green. I have tied it as I first encountered it (Jim Cope via NWFFO) , on a Tiemco 200R hook. A down eye hook could be used. It is a slender pattern, with the head/eyes barely thicker than the body.
The tail is pheasant tail fibers tied into and no longer than the length of the abdomen. A body (abdomen) of dubbed hare’s mask, kept very slender. A ribbing of Silver Krystal Flash is wound up through the dubbing toward the plastic dumbbell eyes. The wingcase was tied in first with the tips extending out over the eye. I plan this so that when the tips are pulled back over the top of the eyes/thorax, they extend only half way back to mid shank and no further. Keep the head slender and dub around the plastic eyes. Once the pheasant tail fibers are secured with thread wraps behind the eyes, cut the top pheasant tail fibers to form blunt ends. I have also tied this wing case as a combination of pheasant tail fibers for the legs and paint brush bristles for the wingcase.
Mix the colors between brown, tan, light to dark green. Swim it toward shore or at least parallel in shallower depths.
