How to tie it
Slide the gunmetal tungsten bead onto the TMC 3752, mount the hook and run a waxed 70 denier thread base back toward the bend.
Take about three of the soft, light fibers from the base of a gray-brown peacock herl and tie them in at the bend for a short tail; trim the butts and cover them with thread so the underbody is smooth.
Dub a very thin, tight noodle of caddis green Quick Descent dubbing onto the thread; this material grips thread exceptionally well, so use less than you think you need.
Tie in the green copper wire at the bend, then dub the abdomen forward to about the 60% point, building it up slightly as you go.
Rib the abdomen forward with open turns of the copper wire, tie off and trim.
Back the thread up over the front of the abdomen and tie in a clump of brown Z-lon there, tips pointing rearward, as the wing case. Trim the clump so it is manageable and leave it lying back for the moment.
Dub a small amount of metallic olive Quick Descent dubbing onto the thread and build the thorax from the wing case tie-in forward to just behind the bead.
Pull the brown Z-lon forward over the thorax and tie it down behind the bead, then trim.
Add a touch more olive dubbing to cover the tie-down, whip finish behind the bead and trim the wing case butts short.
