Now that many of us are in tying mode, I thought it might be interesting to start a favorite fly "thread." What I envisioned was not a series of comments on beloved standard ties, but rather, for those who are willing, descriptions of unusual but effective flies, especially ones that show tough fish something new. I'm starting with a fly I've kept to myself and a few friends for years, but, given Gonzo's generosity, feel a bit silly not sharing now. I first tied it as a caddis.
This caddis is easy to tie with a little practice, and it has taken some very picky, hard-pressured fish on Tulpehocken Creek in Pennsylvania. It is based on the Tulpehocken Creek Outfitters’ CDC pattern often used on the stream, but it is tied upside down, with the hook entirely hidden in the wing. I typically use a Varivas 2300 ultra midge hook for the strong light wire and wide gap. I have had some success with a Daiichi 1640 also, and a Tiemco 2488, Dai Riki 125, or similar hook would probably work.
Tie in a short sparse ginger antron or z-lon shuck, dub the body with an appropriate color for the abdomen, and then switch to a bit of darker dubbing nearer the eye. (From time to time I rib the abdomen with crystal flash.) Leave an eye length or two of the hook bare just behind the eye for tying in the CDC. Then turn the hook over so the point is up, stack three or four CDC feathers on top of each other, then holding the feather ends with left thumb and forefinger, strip off fibers on one side with the right thumb and forefinger. Next find a way to turn the feathers over in your left hand, keeping them stacked and lined up. (I slip the body end of the feather shaft between two fingers of my right hand, let go with my left and turn my left hand over to regrasp the stacked feathers upside down.) Then, carefully raise the right thumb, making sure the stripped fibers stay down on the right forefinger with gravity’s help. Move your left hand to lay the fibers on the unstripped stack right down on the stripped fibers, tips to tips, butts to butts. Grasp the tips of all the fibers with your right thumb and forefinger and strip CDC fibers off the other side of the stacked feathers. This takes some practice, and results in a few messes before you develop a way of doing it, but you should ideally end up with a nice bunch of CDC, with butts all together. Work the fibers into a rolled “paintbrush” with all the butts together. Then pinch tie this bunch, butts forward over the eye, tying down just behind the eye with a couple of turns of thread. Then lift the butts and lay down some wraps back right against the first couple of tie down wraps to bind the wing in tightly sandwiching it between the initial wraps over it and the next ones under coming back. Next, whip finish under the wing butt fibers just behind the eye and trim the butts to expose the hook eye. Cut carefully to avoid cutting the thread. Then angle your scissors to cut the CDC tips forming the end of the wing at a slant, to imitate a caddis wing shape, cutting the wing about even with the end of the shuck.
This fly can be adapted to a mayfly dun (or perhaps a cripple) by shortening the wing. You can use a shuck or split microfibbets for the tail. As a mayfly it doesn’t always work when you might think it should, but it often does and it can be a godsend in extreme glare because you can really see the fly. I’ve had luck with baetids, Hendricksons, PMD’s, and dortheas with this pattern, and it can be skittered during an emergence with deadly effect at times, especially with caddis, baetids and dortheas.
