The copper john is probably one of the most popular modern-day fly creations. First thought out by John Barr in 1993, he only started to fish the pattern with great confidence from about 1996.
The latest and updated version of the copper john made use of a 2x heavy hook and minute epoxy on the wingcase. The 2x is a simple double-length hook shank this gives the body a great profile. The fly usually uses a gold bead and has thorax peacock herl legs ending just behind the bead.
The versatility of the pattern is evident in its design and can be used for many different species. Wrapped lead wire on the hook under the thorax, gives the fly extra weight to get down to feeding columns faster.

How to Tie a Copper John Fly Step-by-Step
Slide your bead on the hook.
Lock your hook in the vise, making sure it is secure and not too close to the tip of the jaws, as the hook may slip when you apply tension to it. I advocate using barbless hooks where possible to ease the removal and minimize the damage done to the fish.
If you want to add more weight, you can make a few lead wraps around the shank after you have slipped the bead onto the hook ending behind the bead. Start with a solid level thread base to work with.
Run the tying thread up and down the shank creating a slight underbody taper from behind the bead back to the tail. This is a good habit to do in fly tying, ensuring the body has the correct taper.
Tie in the 2 brown goose biots, making sure they cross over each other as seen in the above picture. Once they are tied in place secure them with a few more tight wrappings. Make sure they come off the side of the hook with butt ends protruding.
Trim off the butt ends of the biots and create a body taper on the hook shank from the head, back to the bend of the hook. This is an important step.
Tie in the Ultra copper wire and wrap it forward, taking care to make the wraps even. Once you have the line continue wrapping the wire forward ending on top of the hook. A strand of pearl can also be added at this stage if required.
Tie off and cut the wire, allowing enough space for the thorax and wing case to be tied in. Take your time here to examine the wire wrapping as you want them to be as symmetrical as possible and have a lovely taper to them. You can always rewrap until it’s perfect if needed.
At the front end tie in the partridge feather or pheasant feather, tips first followed by the 2 peacock herl strands. Make sure the pheasant tips are extended by 4mm as they will be pulled back and become the extra legs. This is a tricky part but they do give the fly extra bugginess.
Take the peacock herl strands and wrap, twist them up to form one strand. Wrap forward until behind the bead, tie off and trim.
Pull the pheasant fibers forward and lock them in position with the thread. Pull the point fibers back, down and secure them with 2 more thread wraps. Trim the pheasant feather excess and finish off the fly by making a decent collar. It is here where you can cover the thread black with a marker.
Tie off the fly by whip finish, apply some epoxy to the wingcase and thread, set with the UV torch. The epoxy finish gives the fly an emerger style attraction as well which can prove to be very deadly.
How to fish the copper john
There isn’t a way you cant fish the copper john, to be honest. The traditional way would be to single nymph the run with as little drag as possible. The more modern approach would be to dry-dropper the copper john or Euro nymph it.
Whichever way you choose to fish it, it is a very effective pattern, and it’s worth tying a few different weights and sizes. You never know what you will need to throw in the mix.
