1. Start with a bead head on a caddis or scud hook. This is 2mm black bead on a #16 TMC 2487BL hook

2. Tie in Small clear vinyl D rib and a piece of Opal Mirage tinsel

3. Wrap the tinsel forwards first

4. Followed by the D rib, make sure the D is up!

5. Dub a thick thorax leaving a little room behind the bead

6. Tie in a CDC feather by the tip. I’m not sure this is a true CDC feather. I pull them off the ducks backside around the oiler puffs that are the true CDC feathers.

7. Wrap the CDC Feather like a soft hackle, 2-3 wraps. Break off the tips to length rather than cut them with scissors. Add another very small bit of dubbing to help sweep the CDC back.

8. The opal under the D-rib makes a very good imitation of an emerging pupa

As usual this is probably just another variation of a fly that a dozen other people have come up with.
