Kim's Cased Caddis
By Al and Gretchen Beaty

Inspiration for this pattern came from two directions. After purchasing a package of Caddis Tube Bodies from Umpqua, Kim was browsing through Gary LaFontaine's marvelous book Caddisflies looking for ideas on how to effectively use the new material. Gary us well known for his woven-body flies, so it was only natural to put the two together.

When Kim first started tying this fly it was intended to be an artistic rather than fishing fly. To his surprise it proved effective on the water, especially after replacing the pheasant-tail legs with those constructed from rubber.

Kim fishes it without weight, casting upstream and allowing it to dead-drift back downstream. The Cased Caddis is most productive in clear, moderately fast-moving water like sections of the Provo or Weber rivers near his home in Utah.

Tying Kim's Cased Caddis

    1. Start a thread base about one eye-width back on the shank. Wrap back to the first bend near the middle of the hook. Cut a four-inch segment of yellow and olive tubing. Lay the olive aside for a moment and bind the yellow to the off side of the hook shank ending near the eye. Tie on the olive to the near side ending in the middle of the hook. Be sure the tubing is on the sides of the shank.

    2. Start the body by placing an overhand knot in the tubing, slipping it on the hook, and then tightening it. Be certain to keep the olive on the top and the yellow on the bottom. Place a series of these knots on the shank, each one getting closer to the center of the hook. Some tiers find this operation easier if they turn the vise so the hook points either toward or away from them.

    3. Once you reach the center of the hook, tighten the last knot then bind the two tag ends of the tubing to the shank. Trim away the excess then apply a thread base to the rest of the shank ending up back in the middle. Whip finish the thread and trim it off.

    4. Apply black thread to the hook directly behind the hook eye. Select six black pleasant-tail fibers and bind them to the underside of the hook as legs. Trim away any excess fibers. Dub a black head, whip finish and cut off the thread.

    5. Trim the body so it is as long as the hook shank. Remove the hook from the vise and slide the point inside the body. Half way into the tube pierce it with the point and slide it part way onto the shank.

    6. Apply a coating of super glue to the theread wraps and finish sliding the body tube on the hook shank until it reaches the woven body completed in Step 3. Hold the tube in place until the super glue works its magic.

    7. Remove the hook from the vise and secure it in a pair of hemostats. Mix five-minute epoxy and coat the body tube with it. While it is still wet, dip it into a container of fine gravel making certain it is evenly coated on all sides. Kim uses parakeet gravel available at pet supply store, or fine gravel from the body of water he plans on fishing.

    8. Here is Kim's rubber leg version. This has become our go-to searching pattern for streams we fish in Idaho. If caddis are in important insect in your part of the world you owe it to yourself to try this pattern. It is awesome! ~ Al and Gretchen Beatty
