This classic trout pattern was originally developed in the early 1900s. It is tied with palmered hackle of two contrasting colors. The main body is tied with a dark color (traditionally brown) for high visibility by the trout looking up, with a couple turns of a light color (traditionally white) for high visibility for the angler - particularly in low light conditions.
How to tie a Bivisible Fly
Step
1
Place the hook in the vice and lay a thread base. In this fly, it is important to keep an even thread base at all times.
Step
2
If you're choosing to tie in a tail, cut a few fibers from a brown hackle feather and secure them at the bend of the hook.
Step
3
Prepare a brown hackle feather and tie it in at the base. Be sure to keep the bare stem at a length where you can keep an even thread base.
Step
4
Palmer the brown hackle feather forward to around 3/4 the length of the hook shank. You should only leave enough room for two or three turns of the white hackle. Tie off and snip any excess feather.
Step
5
Prepare and tie in a white hackle feather immediately in front of the palmered brown hackle, again keeping an even thread base over the bare stem.
Step
6
Palmer the white hackle forward leaving just enough space for a small thread head. Tie off and snip any excess feather.
Step
7
Wrap a small head with the thread, whip finish, and apply head cement.
