The Ke-He wet fly is a classic pattern known for its effectiveness in attracting trout and other freshwater species. It typically features a body made of peacock herl, which gives the fly an iridescent green hue. The tail and wing are usually made of light brown or ginger hackle fibers. The wing is tied in over the body, giving it a more streamlined profile. The hackle, often brown or furnace, is wound just behind the wing, providing movement in the water. The Ke-He fly is versatile and works well in both still waters and rivers.
