由 Dawn patrol Copper John
A fast-sinking nymph that imitates mayfly and stonefly nymphs, featuring a weighted copper body for rapid descent.
How to Tie the Copper John
The Copper John is tied on a short or medium shank hook with a weighted profile. Its body is formed by tightly wrapping copper wire around the hook shank, creating a cylindrical shape and adding substantial weight. Wire ribbing enhances segmentation and durability. The thorax is crafted from peacock herl for a contrasting texture, while the wing case is made from thin, flat materials like Flashabou or Thin Skin, secured behind the bead head. The fly is finished with a tungsten or brass bead for extra weight and visual appeal.
What the Copper John Mimics
This versatile pattern imitates various subsurface insects, including mayflies, stoneflies, and caddisflies. Its realistic profile, heavy weight, and natural movement make it highly effective for targeting fish that feed on nymphs and aquatic insects. The Copper John acts as a generalist pattern, suggesting multiple food sources to fish.
Where to Use the Copper John
Effective in rivers, streams, lakes, and ponds, the Copper John excels when fish are feeding near the bottom. Its weight makes it ideal for deep or fast-moving water, ensuring quick descent. Fish it using dead drifting, swinging, or nymphing techniques with an indicator or tight line. Adjust depth and retrieve speed to match feeding patterns for optimal results.
