The D rib Caddis is a very useful and effective fly. You can heavily weight it and use as a point fly in a Czech/euro nymph rig or just use the bead for a dropper fly in a Czech/euro nymph rig. You can also make this fly into an attractor pattern and use different colors and some flashy dubbing.
Ingredient List:
Hook- light wire scud hook sz. 12-18
Thread- 70-140 denier thread color to match D rib
Abdomen- D rib in this case chartreuse but you can change it up
Thorax- Black Caddis life cycle dubbing
Bead- Gold tungsten sized to hook
Crush the barb and place the hook firmly into your vice so only the tip is showing
Run your thread to about 1/4 of the way down the hook shank, snip your thread and wrap back up.
Tie down your D-rib so that the flat side is facing the shank, then wrap back forward.
Wrap your D rib up the shank to about an eight of an inch behind your bead, and firmly tie it down.
When you go to snip the D rib, pull the D rib taught and then snip so that there is barely a snub left.
Once your D rib is cut, wrap a thin dubbing noodle of the black Caddis life cycle dubbing.
\
Wrap the noodle up to the bead so it pushes against it.
Whip finish, use head cement, and your fly is ready to put in your box!
