Tying Instructions

1. Attach the thread to the hook shank behind the eye.

2. Lay a thread foundation to the bend of the hook.

3. Select a saddle hackle sized to the hook. Remove the fibers from the base of the hackle and secure the hackle stem to the side of the hook shank at the bend of the hook. The shiny side of the hackle should face the eye.

4. Wrap the hackle forward with touching wraps, careful not to trap any hackle fibers. Wrap up to the 3/4 position of the hook shank and secure with a couple of thread wraps.

5. Trim off the tag end of the rear hackle and apply a few more thread wraps to secure. Attach a white hackle at the 3/4 position with the shiny side facing forward.

6. Apply 5-6 wraps and secure behind the eye with a couple of thread wraps.

7. Trim off the tag end and build a small thread head.

8. Apply a whip finish.

9. Add some head cement.

10. The finished Brown Bivisible. If done correctly, you do not need to trim the bottom hackle tips. Quality hackles are uniform in size and will achieve a even profile to the fly.

Edward Hewitt

Bivisible

The Bivisible is a classic fly that was introduced by Edward Hewitt (1866-1951) in 1926 in his book, “Telling on the Trout”. Mr. Hewitt states: “Dark colors are more visible to the trout from below than light colors, and, therefore, take more fish under most conditions and are more generally used. They are often, however, more difficult to see on the water than the lighter flies.”

“This is the reason for my favorite design of fly which I call the BiVisible which consists of a palmer-tied brown hackle on the head of which is wound a small wisp of white hackle. The white resting against the brown becomes very visible in most lights to the angler; on the other hand, the trout see the brown hackle from below better than any other color used. This fly is by far the best of any I have yet seen for all species of trout and it is based on a sound physical principle.”

Two Contrasting Colors

It has remained a standard attractor fly through the years either mimicking a skating caddis, ants, beetles, or a midge cluster. The Bivisible was developed to use two contrasting colors. The darker colors are more readily visible to the trout while the contrast of the light against dark colors allowed the fly fishers to see the fly on the water more easily. The pattern is often used in faster broken water since it has high floatability. The use of palmering the hackle over the body is a old technique going back perhaps to the 1700’s. Mr. Hewitt presented the first Bivisible as a Brown Hackle body with a White hackle wisp at the head. This pattern has been recognized as the Brown Bivisible.

Hewitt did not add a tail to the pattern but tails are often seen on this pattern. Some use hackle fibers, others use hackle tips for the tail. Using the Catskill proportions, the tail length should be about the same as the shank length. Different combinations of hackles have been used by tiers, Mr. Charles Merrill of Detroit, MI is credited with the Badger Bivisible sometime in the 1930’s and Hank Wilson, a guide on the White River in Arkansas is credited with the Bulbous Bivisible in the late 1970’s.

Proportions

Often the pattern is tied on a standard dry fly hook such as the TMC 100. However, for a more traditional appearance, you might consider using the Daiichi 1170 which is a 1X long Traditional Dry Fly hook with a larger barb. This extra length provides nice proportions to the fly. Both hackles should be sized to the hook. The rear hackle should cover the lower 3/4 of the hook shank and the front hackle should be about five turns just in front of the rear hackle. Hackle tips should be even across the length of the shank. Maintain a smooth even thread wrap foundation to the hook shank to ensure that the hackle fibers will be perpendicular to the shank.
