Diving Glossosoma Caddis


Imitates egg-laying adult saddle-case caddis (Glossosoma). This caddis is very common on small streams as well as some larger waters.

Many anglers use Soft Hackles to imitate diving caddis, but most of these lack the flash to accurately imitate the natural insect.

How to Fish

Use trout indicator or tight line nymphing tactics. Surface swing tactics also work well.

Tying Instructions

1. Slide bead on the hook and position it near the head of the fly, but don't tie it down. Tie in thread.

2. Tie in fine gold wire.

3. Dub 1-2 wraps of insect green dubbing. Dub the rest of the body with the brown dubbing. Dub only 2/3 way up the hook.

4. Slide bead down to body, make wrap of thread over the bead to secure it in place. Try to keep your thread on the top of the bead, so that it will be concealed by the wing.

5. Wrap up the gold wire and wrap it over like the thread.

6. Make one wrap of brown dubbing in front of the bead to secure it in place.

7. Tie in partridge feather by folding feather around hook (keep the tip on top for the wing) so that you get a "soft hackle" effect without wrapping the hackle. Tie off and trim excess.

8. Tie in Krystal Flash and trim to the length of the wing. Tie off and trim excess.

9. Add in pheasant tail or Krystal Flash antennae (optional).

10. Make three half-hitches and lacquer head.
