A dry fly resembles an insect floating on the water surface. Dry flies can also imitate mice, frogs. A dry fly is often tied on a light hook so it can float easily.
Dry flies can be tied to imitate insects on the water, such as Pale Morning Duns, or to attract fish to rise without imitating any one specific insect, such as a Royal Wulff or Adams dry fly. The traditional dry fly has a few basic parts: tail, body, wing, hackle, and head. Floatation of the fly can be achieved in a variety of ways. A dry fly traditionally uses the surface tension of water to float. The fly will ride on the hackle and tail, and in some cases the hook point will not break through the surface. Closed-cell foam can be used in the construction or sometimes a CDC feathers, to hold molecules of air. Some dry flies must be lubricated with a special floatant before presentation to preserve buoyancy
Dry fly technique
In order for the dry fly to float tantalizingly on the water surface, it may require periodic drying after it is pulled from the water. This is accomplished by several rapid strokes or whips of the airborne fly and fly line, called "false casting".
A dry fly may be fished upstream or downstream. Casting upstream generally keeps the angler out of the view of the fish while casting downstream may facilitate casting to productive holes.
A wet fly resembles an insect under the water surface. Wet flies can imitate aquatic insects, drowned insects, or emerging insects (emergers). Wet flies are traditionally tied with a tail, body, wings, and soft hackle.
Wet fly technique
In current, a wet fly may be fished upstream, across stream, or down stream. In slow pools on a large river, or in lake fishing the line may be retrived slowly by a figure-of-eight retrieve (coiling the line in the palm of the hand). On still water, the wet fly may also be retrieved by this method, or by stripping line.
A streamer fly or streamer can be used to mimic injured baitfish. Streamers are normally larger in size than other types of artificial fly, and can be used to catch predatory fish of almost any size. Fish will bite streamers out of aggression while protecting spawning areas, out of curiosity, or when feeding. The big showy Atlantic Salmon flies, bucktails (hairwing), and feather wing flies all fall into the streamer category.
Streamer fly technique
The fishing technique with a streamer is much the same as with a spoon lure. Casting across and downstream is the traditional presentation. Retrieves can be fast or slow and erratic to imitate an injured baitfish.
A nymph resembles an insect or stage of insect living underwater. Leeches, mayfly nymphs, caddis fly larva, and diptera can all be imitated by nymphs.
Normally a nymph is tied on a heavier hook, sometimes with an added weight in the body or head to keep it underwater during presentation.
Nymphs can be fished successfully upstream or down. A large percentage of what fish eat is found living underwater and imitated by nymphs. Without the benefit of seeing the fly, the flyfisherman must distinguish a fish's take from the normal tug of river current. Many nymph fishermen rely on small bobbers, brightly-colored yarn to see the fish strik.
Fly fishing is a distinct and old angling method, most renowned as a method for catching trout and salmon, but today used for many other species such as pike, bass, and carp, as well as a wide range of saltwater marine species, such as tarpon and bonefish. Artificial flies are tied onto a hook with thread, fur, feathers and other materials. The material is tied in sizes and colors to match naturally occurring food, or simply to excite a fish into striking the fly.
