It's also one of the most versatile nymphs if you want something that will have a high attraction rate, regardless of the water you're fishing in. It's able to bring fish right to your net in a vast range of conditions, and it's very buggy as well. This means that it can imitate any nymph that the trout may find tasty.

    Prince Nymph

    4. Prince Nymph

    The prince nymph is quite easily ranked as being one of the best fishing nymphs of all time. It's ranked just as high as the flashback hare's ear, and it's got a defined profile. It's unmistakable, and fish tend to take it with a considerable amount of enthusiasm. It's typically used in faster waters, and it can be used as a stonefly imitation too.

    The Copper John is a nymph which is excellent at catching fish. John Barr invented this in 1993, and it's a fantastic fly if you want to catch both trout and grayling. It's ideal for use in deep or faster water, and it's a great addition to your existing setup. The fly can attract fish in still water as well as in rivers. The fact that it can do this comes down to its weight profile.

    The copper wire is twisted around the hook shank, which helps the fly maintain a uniform weight profile. You can also get the fly to the depths of the water, where the fish may be. This is especially the case earlier in the season, depending on where you are, as the fish will tend to linger around the bottom.

    6. Barr Emerger

    Barr Emerger is very high on a lot of people's favorite flies. It is a very simple concoction and includes feathers and dubbing. The patterns, however, make this a fantastic fly.

The color variations also match in with the hatches that you will see regularly. Just make sure that you use the right color according to the time of year you fish at.

    This fly is essential for anyone who wants to take their fishing experience to that next level. It's an essential tail water pattern, and it's excellent at getting trout to bite.

    8. Hot Wing Caddis

    The Hot Wing Caddis is an improvement on the famous Elk Hair Caddis fly. The main difference is that Hot Wing Caddisflies are a lot more visible thanks to the bright color on the wings. This is a modern twist that can be tricky to use, but you'll at least have no trouble spotting your fly, thanks to its high visibility. This is what attracts many trout and ultimately why it's such a great fly for both beginners and experts alike.

It's very versatile, and it will usually draw a strike in hardly any time at all.
