Fly Tying: Balanced Ruby Eyed Leech

Updated: Jan 23, 2019

The Balanced Ruby Eyed Leech is one of the most effective still-water patterns that we use for Brook Trout here in the Adirondacks. These flies are simple to tie and simple to fish! This short step by step tutorial shows you how we tie these flies. If you are not a fly tier and would like to purchase this fly, simply send an order request to!

Step 1: Place your hook in the vise and start your tying thread

Firehole 516 Size 12

For this pattern I use a Size 12 Firehole 516 Competition Jig Hook and UTC 70 Yellow Olive thread.

Step 2: Select a pin and slide on a 1/8" gold brass bead and a small ruby Killer Caddis bead and attach it to the hook

Assembly Process

The brass bead on the pin will help aide the "balanced" effect of the fly. NOTE: Watch your thread wraps on the back end of the pin as it can be sharp and cut your thread.

Step 3: Add some fly tying head cement to your thread wraps

The head cement will ensure that the pin/bead assembly will stay secured to the hook!

Step 4: Tie in a clump of Arizona Simi Seal for the tail

Secure tail material

For this color combination I use Golden Olive Arizona Simi Seal Dubbing. Secure the tail to the hook and wrap over the butts to form an even body.

Step 5: Dub the body of the fly using Arizona Simi Seal Dubbing

I use the same Golden Olive dubbing for the body of the fly. It is important to keep the body of this fly relatively even to best imitate the naturals.

Step 6: Whip Finish

Secure your thread by doing two, four turn whip finishes. Head cement is optional here.

Step 7: Brush out the body

A simple toothbrush is an extremely effective tool for brushing out the body.

Have fun tying this fly and tight lines!
