Fly tying instructions

Step 1

Slip the Evolution beadhead onto hook, and position the hook in vise. Wrap 3 or 4 turns of lead-wire onto the hook.

Step 2

Push the lead-wire forward and position inside the back of the bead. This helps shape the thorax and add weight to the fly.

Step 3

Attach tying thread and wrap a strong base layer of thread over the lead wire and shank of the hook.

Step 4

Tie in ultra wire for the ribbing.

Step 5

Take a small clump of pheasant tail fibers for the tail and tie-in at the back of the hook.

Step 6

Holding the pheasant tail fibers together, wrap them forward to create the abdomen.

Step 7

Trim off the ends and tie-off. 

Step 8

Rib the abdomen of the fly by wrapping ultra-wire forward in the opposite direction of the pheasant tail. Cut off the excess wire and tie off securely.

Step 9

Tie in several pheasant tail fibers for the wingcase and trim off the butt ends.

Step 10

Dub a tight thorax.

Step 11

Pull the pheasant tail fibers forward and over the dubbing to create the wing case of the fly. Tie down the pheasant tail directly behind the bead. Separate the pheasant tail fibers on both sides. 

Step 12

Position the pheasant tail on either side of the bead and facing slightly downwards. These will represent the legs of the fly. Make several whip finishes with your thread to secure the pheasant tail in position. 

Step 13

Whip finish and cut your thread.

Step 14

Add head cement to your thread wraps and wingcase.

Step 15

Go catch a big fish! The Evolution Mayfly Pheasant Tail is complete!
