The Stimulator is a dry fly popularized by angler, fly tyer and author Randall Kaufmann to imitate large adult stoneflies. [1]

Contents

Origin

The Stimulator pattern is a derivative of earlier stonefly patterns—the Improved Sofa Pillow (1940s) and Yellow-bellied Mattress Trasher (1970s). Many anglers believe the name Stimulator was given to the pattern by Jim Slattery, a Montana angler who renamed his Fluttering Stonefly pattern. Others contend the pattern was derived from the Trude style dry flies developed in 1903. However, the pattern was clearly popularized and promoted by Randall Kaufmann, a fly shop owner, angler and author in Seattle, WA and Portland, OR in the 1980s. [1]

Imitates

Originally tied to imitate large stoneflies, the Stimulator is also useful to imitate adult caddis, grasshoppers and large mayflies. [2]

Fly tying

Fly tying is the process of producing an artificial fly used by fly fishing anglers to catch fish. Fly tying is a manual process done by a single individual using hand tools and a variety of natural and manmade materials that are attached to a hook. Although the recent history of fly tying dates from the middle 1800s, fly tyers were engaged in tying flys since at least 200 AD.

Pheasant Tail Nymph

The Pheasant Tail nymph or PT Nymph or Sawyer’s Pheasant Tail is a popular all purpose nymph imitation used by fly anglers. It imitates a large variety of olive, olive-brown colored aquatic insect larvae that many fish including trout and grayling feed upon.

Artificial fly Lure used in fly fishing

An artificial fly or fly lure is a type of fishing lure, usually used in the sport of fly fishing. In general, artificial flies are an imitation of aquatic insects that are natural food of the target fish species the fly fishers try to catch. Artificial flies are constructed by fly tying, in which furs, feathers, thread or any of very many other materials are tied onto a fish hook.

Woolly Worm (imitation)

The Woolly Worm is an artificial fly commonly categorized as a wet fly or nymph and is fished under the water surface. It is a popular pattern for freshwater game fish and was a very popular fly in the 1950s–1970s in the west. Charles Brooks in Nymph Fishing for Larger Trout recommends the Woolly Worm as a general purpose nymph pattern in most western trout waters in any fly box. Woolly Worms are typically fished in streams, rivers, ponds, and lakes for trout, bass, and panfish. Today, Woolly Worms are tied in a variety of styles and colors to imitate a large aquatic nymphs such as stoneflies, dragonflies, damselflies or hellgrammites.

<i>Favorite Flies and Their Histories</i>

Favorite Flies and Their Histories - With many replies from practical anglers to inquiries concerning how, when and where to use them-Illustrated by Thirty-two colored plates of flies, six engravings of natural insects and eight reproductions of photographs is a fly fishing book written by Mary Orvis Marbury published in Boston in April 1892 by Houghton Mifflin. It was considered by most fly fishers as the standard reference on flies in its era.

Partridge and Orange

The Partridge and Orange is an artificial fly commonly categorized as a wet fly or soft hackle and is fished under the water surface. The fly is a very well known fly with its roots set firmly in English angling history. It is an impressionistic pattern fished successfully during caddis hatches and spinner falls. The Partridge and Orange is traditionally a trout and grayling pattern but may be used for other aquatic insect feeding species.

Royal Coachman

The Royal Coachman is an artificial fly that has been tied as a wet fly, dry fly and streamer pattern. Today, the Royal Coachman and its variations are tied mostly as dry flies and fished floating on the water surface. It is a popular and widely used pattern for freshwater game fish, particularly trout and grayling. Large streamer versions are also used for winter steelhead and Atlantic salmon.

Although 100% of any book listed is not necessarily devoted to fly fishing, all these titles have significant fly fishing content. Included in this bibliography is a list of fly tying, fly tackle, regional guides, memoirs, stories and fly fishing fiction related literature.

Elk Hair Caddis

The Elk Hair Caddis is a dry fly commonly used for trout fishing. The Elk Hair Caddis was created by Pennsylvania fly tyer Al Troth in 1957. He is considered a pioneer in the sport of fly fishing for this invention.

Royal Wulff

The Royal Wulff is a popular artificial fly used for dry fly fishing. It is an attractor pattern and a descendant of both the Royal Coachman fly and the Wulff style of hair wing flies named for Lee Wulff.

Adams (dry fly)

The Adams is a traditional dry fly primarily used for trout. It is considered a general imitation of an adult mayfly, flying caddis or midge. It was designed by Leonard Halladay from Mayfield, Michigan in 1922, at the request of his friend Charles Adams. The Adams has been considered one of the most popular, versatile, effective and best selling dry flies since its creation.

Dave's Hopper is an artificial fly used for fly fishing, designed to imitate adult grasshoppers and other Orthoptera species. It is considered a dry fly terrestrial pattern. It was designed by fly tyer and angler Dave Whitlock, and combines the best aspects of Joe's Hopper and Muddler Minnow patterns.

Parks Salmonfly

Parks' Salmonfly is a traditional dry fly imitating adults of the family of giant stoneflies or salmonflies (Pteronarcyidae). The most commonly imitated species is Pteronarcys californica or salmonfly common throughout Western North America from British Columbia to California.

Alexandra (wet fly)

The Alexandra wet fly originated in Scotland in the 1860s. The artificial fly is also known as the Lady of the Lake, the fly was named by English angler Major William Greer Turle to honor Alexandra, Princess of Wales. The fly is distinguished by the heavy peacock herl wing and silver body which makes the fly resemble a small baitfish or fry. The Alexandra proved to be a very effective fly for trout in lakes and streams in England and Scotland in the late 19th and early 20th century. Many fly fishing purists derided the fly and its use was once banned on many English waters.

Sakasa Kebari

The Sakasa Kebari or reverse-hackle fly is an artificial fly most associated with the Japanese style of tenkara fishing but can be used in most freshwater fly fishing. The Sakasa Kebari is usually defined by firstly its reverse hackle and secondly by its simplicity as compared to western style flies. This fly was originally created to be used in the small, high gradient streams in Japan while fishing for native trout and char.

Red Tag (artificial fly)

The Red Tag is an artificial fly originally designed as a dry fly for grayling and trout in the north country of England. The fly pattern, when introduced into Australia, particularly Tasmania, became extremely successful and popular for brown trout and remains today as one of the most essential flies for Australian fly anglers.

Wulff series of dry flies

The Wulff series of dry flies evolved from a dry fly style conceived by angler Lee Wulff in the 1930s.

Brown Bi-visible

The Brown Bi-visible is an attractor style dry fly first promoted by angler Edward Ringwood Hewitt in his work Telling on the Trout (1926). A generic, high floating pattern, the fly was designed to provide visibility of the fly for the angler in low light conditions. Darker colored flies were extremely difficult to see in low light and glare conditions. The addition of light cream colored or white hackle at the front of the darker body made the Bi-visible easier for the angler to see on the water. Ray Bergman in his seminal 1952 work Trout gave the following credit to the Bi-visible pattern:

I gave Bivisible flies complete and indisputable credit. I believe that I even intimated they were the last word--the ultimate in dry flies. I was so sold on the Bivisibles for one complete season that if trout wouldn't take one, I figured they wouldn't take anything, and I was perfectly satisfied with this decision.

Humpy fly

The Humpy fly is a popular and effective dry fly used by fly anglers for trout in fast-water conditions.

Salmon fly patterns Artifical fly patterns immitating the Salmon fly for fly fishing.

Salmon fly patterns are an important collection of artificial flies used by fly anglers to imitate nymphal and adult forms of Pteronarcys californica a giant stonefly or salmon fly. Salmon flies are common in high gradient, freestone rivers and streams from Western Canada throughout the Western U.S. to Mexico in the Rocky Mountains and coastal mountain ranges. Nymphs live for three to five years before adult emergence which typically occurs in late Spring or early summer. The long lifespan of the nymphal form provides year-round angling opportunities for fly anglers.
