- Body: Spun deerhair
- Hackle: Red or Furnace cock
- Antennae: Hackle stems
- Tying thread: Black
- Hook: Size 12-14 Long shank
This is again a relatively simple pattern, but it does require you to be able to spin deerhair.
Begin by tying the silk onto the hook in the normal way. It is wise to use a thicker for this tying as you will need to put tension on the deerhair to spin it. Run the silk down to a point opposite the barb of the hook. Take a pinch of deerhair and secure it to the shank of the hook. As you tighten the silk, allow the hair to flare around the hook shank. Keep repeating this process until the about four fifths of the shank is covered.
The deerhair now has to be shaped, using a sharp pair of scissors. The required profile is a tapered sausage, with some of the deerhair extending about 0.5 cm beyond the bend of the hook. Try to imitate the triangular section of the wings of the natural fly.
Now, strip all the flue from two similarly sized cock hackles, and tie these in to project over the eye of the hook by about 2 cm. Trim off the excess and tie in a red or furnace cock hackle. Two turns of the hackle should be enough, tie it in and trim off the excess. Tie off with a whip finish and carefully varnish the head.
The adult caddis, more usually known as the Sedge Fly, hatches at the surface of the water, usually in the evenings and often in large numbers. Sedge flies often skate across the surface beefed they take to the air. Because deerhair is naturally buoyant, this fly will sit high on the surface, imitating the adult and creating the same sort of surface disturbance as the natural. Fish this fly singly as a dry fly.
