Mercury Pheasant Tail
The Mercury variant of the classic Pheasant Tail Nymph replaces the metal bead with a clear glass bead that adds subtle flash and imitates a gas bubble, a key trigger for trout. This pattern retains all the fish-catching qualities of the original PTN—natural profile, copper wire segmentation, and peacock herl thorax—while adding the deadly Mercury glass bead for extra effectiveness on selective fish.

How to Tie the Mercury Pheasant Tail
- 1
Step 1
Slide the clear glass bead onto the hook and secure in the vise. Start thread behind the bead and lay a smooth base to the bend.

Step 2
Select 3-4 pheasant tail fibers, align tips, and tie in at the bend as a tail about half the shank length. Secure butts along the shank for a smoother underbody.

Step 3
Tie in a length of fine copper wire at the base of the tail for ribbing.
- 4
Step 4
Tie in 3-5 pheasant tail fibers by their tips. Wrap forward in even, touching turns to create a slender, tapered abdomen covering about two-thirds of the hook shank. Secure and trim.

Step 5
Counter-wrap the copper wire forward to segment and reinforce the body. Tie off behind the bead and break off excess.
- 6
Step 6
Tie in a small clump of pheasant tail fibers pointing backward for the wingcase.
- 7
Step 7
Tie in peacock herl and wrap a small, bushy thorax behind the bead. Tie off and trim.

Step 8
Pull the wingcase pheasant tail fibers forward over the thorax and tie down. Optionally pull remaining fiber tips back along each side as legs.
