How can you catch that trout regularly? Know your dry flies. When you’re fishing fast water and slow water that determines which type of dry fly you use. Since attractor dry flies imitate dozens of different insects, they are made to float when they are fished in fast water. Rarely, imitative dry flies are fished on fast water because they don’t float as well as the attractor dry flies. On slow water trout can see better so imitative dry flies should match just one hatch.
Attractor dry flies are fished in fast water because they float. The keys to tying attractors is their bulginess and flotation. To add bulginess to a fly it needs to resemble dozens of insects by sometimes adding parts of flies to them. As if you’re tying a stimulator fly, which imitates stoneflies and craneflies, add legs to the middle part of the body just in front of the wing. Floatation comes from stiff water repellent materials. Usually, their bodies are made of synthetic materials or beaver hair. The wings are a big part of the flotation so they should be deer hair or calf tail since hollow hair floats. Attractor dry flies catch fish!
Imitative dry flies are harder to tie and fish. Imitative dry flies are fished on smooth water and fished precisely perfect because the trout can see better. Rarely, imitative dry flies are fished on fast water because they don’t float as well as the attractor dry flies. When you tie these dry flies tails, there tails need to be positioned perfectly and wings straight and in the right position. As you’re out fishing and if you don’t have the fly, which is the exact match for the hatch, find what the trout are eating and look at the underside. Then observe the size, shape, and color of the bug and match that to an imitative dry fly in your fly box.
Regarding attractor dry flies, they float and catch fish in fast water. Try to have the right imitative dry fly when fishing slow water. Obviously, match the hatch! Significantly, you need to know the difference between attractor dry flies and imitative dry flies. When you are fishing these dry flies remember imitative dry flies, which imitate only one type of bug, are fished in slow water because the fish can see better. Attractor dry flies are fished in fast water because they float better than imitative dry flies.
