For decades the Fluttering Caddis has been my number one dry fly in terms of trout caught from March through November. I use about eight variations in wing and body color in a variety of sizes. I use the Orvis Caddis Guide booklet (can't remember the exact title) which is a very good guide for the prevalent caddis hatches in the East and West.
You may want to try a couple of variations to the original pattern that I have incorporated:
- For the down wings, I blend hackle fiber colors to get a fairly realistic imitation of the natural. I don't know if the trout care, but it looks great to me.
- I normally use a carefully tapered fur body for the body
- Since one of the purposes of the Fluttering Caddis is to create a gentle twitch or skip on the surface, I have found that using a hook size that is significantly smaller than the overall size of the fly is most effective. The overall weight of the fly is less, and the weight of the bend of the hook is moved away from the tail end of the wings, which bear the brunt of the movement on the water. As a guideline, I use a hook that is 4 sizes smaller than what the length of the fly appears. For example, if you use the Orvis Guide, when they call for a size 14 fly, they show the size the artificial should be. I use a size 18 hook, but the overall size of the artificial is the same. I will post some pictures when I get a chance.
Leonard Wright's innovations deserve more recognition than he usually receives. He was the first to document the tying method and procedure for fishing the downwing "fluttering" patterns. If you read his two books on the subject, the second being "Fly Fishing Heresies", you will see that he was looking for an effective technique for fishing from Spring through Fall, with much of his fishing done during Summer conditions. His Fluttering Caddis style is the best design I have ever found for all 3 seasons, especially when there is no hatch. I have tried the Elk Hair Caddis and Cut Web Wing Versions of caddis which work fine on a dead drift, but they are not as effective when imparting life to the fly - which makes all the difference in the world when done properly.
