Royal Wulff
The Royal Wulff stands as one of fly fishing's most iconic and recognizable attractor dry flies, featuring a distinctive red floss body, white calf tail wings, and peacock herl shoulder and tail. Created by legendary fly tier Lee Wulff in the 1930s, this pattern revolutionized dry fly fishing by demonstrating that high-floating, visible flies could outfish traditional imitative patterns in many situations. The Royal Wulff's bold design makes it visible to both anglers and fish in broken water, while its buoyant construction keeps it riding high through turbulent currents. As an attractor pattern, the Royal Wulff doesn't imitate any specific insect but rather suggests the general size and silhouette of various mayflies and caddis. The bright red floss body provides a strike trigger that fish can see from a distance, while the peacock herl adds an iridescent quality that mimics the natural sheen of many aquatic insects. The white calf tail wings stand upright like a classic mayfly, creating a silhouette that trout recognize as food even when they're not feeding on a specific hatch. This fly excels in pocket water, riffles, and runs where broken surface conditions make precise imitations difficult for fish to inspect closely. It's particularly effective on freestone rivers with bouldery structure and fast currents, where trout must make quick decisions about whether to strike. The Royal Wulff's high visibility helps anglers track the fly through complex currents and heavy chop, while its buoyant design keeps it floating even after multiple catches or dunkings. The pattern works throughout the summer and fall seasons when terrestrial insects and various mayflies are active. It's especially deadly during grasshopper season, when its size and profile suggest a meaty meal worth rising for. Many experienced anglers use the Royal Wulff as a searching pattern, covering water methodically until they locate feeding fish or determine what insects are active. Its versatility makes it equally effective on mountain streams, medium-sized rivers, and even some larger waters when conditions are right.

Technique & Presentation
Tying the Royal Wulff requires mastering several fundamental dry fly techniques, particularly working with hair wings and multiple hackles. Begin by securing a tail of brown bucktail or moose body hair extending about one shank length beyond the bend. The tail should be sparse enough to split slightly, providing stability on the water. Build a smooth thread base before wrapping the red floss body, which should be slightly tapered and occupy roughly the middle third of the hook shank.
The peacock herl sections at the rear and front of the body are crucial for the pattern's effectiveness. Wrap two or three peacock herls together for durability, creating small but distinct shoulders before and after the red floss. These herl sections should be roughly equal in width, creating a balanced, segmented appearance. For the wings, select quality calf tail that's fine enough to stack cleanly but stiff enough to stand upright. Divide the hair into two equal bundles, position them upright at the thorax, and use figure-eight wraps to separate and secure them.
Hackle selection is critical for proper flotation. Mix brown and grizzly hackles of appropriate size—use the hook gap as a guide, with hackle fibers extending slightly beyond the hook point. Wind the hackles together through the wing base, making several turns in front and behind to create a full, bushy collar. The generous hackle gives the Royal Wulff its exceptional floating ability and lets it ride high even in turbulent water.
When fishing the Royal Wulff, use it as a prospecting pattern in likely holding water. Cast to pocket water behind boulders, seams along current breaks, and the heads of riffles where trout hold waiting for food. The fly works well in a hopper-dropper rig, with a small nymph trailing 18-24 inches behind. In broken water, focus on getting good drifts rather than pinpoint accuracy—the fly's visibility means you can fish it successfully even when you can't see exactly where it lands. Apply floatant generously and false cast to dry the fly between fish, as its buoyant design means it can handle dozens of casts before needing replacement.
History & Origin
Lee Wulff created the Royal Wulff in 1930 as an improved version of the Royal Coachman, a classic wet fly pattern dating to the Victorian era. Wulff recognized that while the Royal Coachman's red and peacock color scheme was attractive to trout, the traditional wet fly design limited its effectiveness in the fast, broken water he loved to fish. By adapting the color scheme to a high-floating dry fly with hair wings and generous hackle, Wulff created a pattern that would revolutionize American fly fishing.
The Royal Wulff was part of Wulff's series of hair-wing dry flies, which included the Grey Wulff, White Wulff, and others. These patterns challenged the prevailing wisdom that dry flies needed delicate feather wings and precise imitation to fool trout. Wulff proved that in the rough-and-tumble waters of the Catskills, Adirondacks, and Canadian salmon rivers, buoyant attractor patterns could outfish traditional designs. His innovations influenced generations of fly tiers and helped establish hair-wing flies as a distinct American contribution to fly-fishing tradition.
The pattern gained widespread popularity in the 1940s and 1950s through Wulff's writings, films, and demonstrations. His advocacy for conservation, catch-and-release fishing, and adventurous angling made him one of fly fishing's most influential figures, and the Royal Wulff became synonymous with his approach to the sport. Today, the fly remains a staple in fly boxes across North America, proof that Wulff's design philosophy—visibility, buoyancy, and general suggestion over precise imitation—continues to catch fish nearly a century after its creation. The Royal Wulff is more than a fly pattern; it's a piece of fly-fishing history that still produces on rivers from coast to coast.

Related Dry Fly Patterns
Parachute Adams
The most versatile dry fly ever created. The Parachute Adams imitates a wide range of mayflies and serves as an effective searching pattern when no specific hatch is occurring. The white parachute post makes it easy to track on the water. Originally tied with conventional upright wings, the parachute version wraps the hackle horizontally around the post, allowing the fly to land flush on the surface with a more realistic silhouette. This low-riding profile is why many experienced anglers prefer it over the standard Adams. The mixed brown and grizzly hackle suggests the mottled coloring of countless mayfly species, from tiny Baetis to larger Callibaetis. On Montana waters, the Parachute Adams is the quintessential searching pattern. When you arrive at the river and nothing is hatching, tie on a Parachute Adams in size #14 or #16 and start prospecting. During active hatches, sizing down to match the naturals makes this fly deadly. It works on every Montana river from the riffles of the Madison to the spring creek-like waters of the Missouri below Holter Dam.
Elk Hair Caddis
Al Troth's iconic caddis imitation is a must-have on every Montana river. The elk hair wing provides excellent flotation, and the pattern effectively matches adult caddisflies throughout the season. Dead-drift, skate, or twitch it; all methods produce fish. The Elk Hair Caddis is one of those rare patterns that works from the moment caddisflies start appearing in spring through the last hatches of fall. The tent-shaped elk hair wing perfectly mimics the profile of a resting adult caddis, while the palmered hackle gives the fly exceptional buoyancy and creates the impression of legs touching the surface. Its durability is legendary; a well-tied Elk Hair Caddis can take dozens of fish before needing replacement. In Montana, caddis hatches are prolific on every major river. Mother's Day caddis hatches on the Yellowstone in late April and May are among the most anticipated events of the season. The Elk Hair Caddis is equally effective on the rock gardens of the Gallatin, the braided channels of the upper Madison, and the tailwater sections of the Missouri. Vary the body color between tan, olive, and green to match local populations.
Stimulator
An outstanding attractor dry fly and stonefly imitation. The Stimulator excels as a top fly in a dry-dropper rig. Larger sizes (#6-8) match salmonflies and golden stones, while smaller sizes (#12-14) suggest various stoneflies and caddis. The Stimulator's genius lies in its buoyancy and suggestive profile. The combination of a heavily palmered hackle, elk hair wing, and robust body allows it to ride high on turbulent water where lesser flies would drown. The swept-back wing silhouette works as both a stonefly and large caddis imitation, making it effective even when no specific insect is hatching. Trout see the Stimulator and recognize it as a substantial, calorie-rich meal worth rising for. In Montana, the Stimulator truly shines during stonefly season on the Madison, Yellowstone, and Gallatin rivers. Tie on a size #6 orange Stimulator during the salmonfly hatch in late June and fish it tight to the banks. As summer progresses, switch to smaller sizes in yellow for golden stones. The Stimulator also serves as an excellent indicator fly for a heavy nymph dropper, especially when wading pocket water and riffles where it can be challenging to track a strike indicator.
Chubby Chernobyl
A modern foam attractor pattern that has become a Montana staple. Virtually unsinkable, the Chubby floats heavy nymph droppers and draws aggressive strikes from trout looking for a large, easy meal. Available in numerous colors. The Chubby Chernobyl represents the evolution of the foam hopper and stonefly genre. Its layered foam body creates a nearly indestructible fly that requires no floatant and rides high on even the roughest water. The rubber legs provide enticing movement, and the flash wing catches light in a way that grabs attention from trout holding deep. Whether tied in tan, purple, pink, or any other color, the Chubby simply produces fish. Montana guides have embraced the Chubby Chernobyl as their go-to dry-dropper indicator fly, and for good reason. It supports one or even two heavy nymphs without sinking, it is visible at long distances, and trout eat it with startling aggression. On the Madison, Yellowstone, and Gallatin rivers, more fish are likely caught with a Chubby on top than any other dry fly. Its effectiveness extends from early July through October, covering the heart of Montana's fishing season.
Purple Haze
A Montana-born variation of the Parachute Adams with purple dubbing. Created in the Gallatin Valley, this pattern has become a regional favorite that outperforms the standard Adams on many days, particularly during BWO and PMD hatches. The Purple Haze takes the proven Parachute Adams template and adds a subtle twist: a body of purple dubbing that seems to trigger something in trout that the standard gray does not. While purists may argue the color is unnatural, the results speak for themselves. Montana anglers have reported for years that the Purple Haze consistently outfishes the standard Adams, particularly on rivers that receive heavy fishing pressure. Theories about why the purple works vary. Some believe that the color more accurately represents the UV spectrum reflected by natural mayflies. Others suggest that the slightly different hue simply stands out enough on pressured water to be noticed without being refused. Whatever the reason, the Purple Haze has earned its place in the top tier of Montana dry flies. It is especially effective on the Gallatin, Madison, and Yellowstone rivers from late spring through early fall.
X-Caddis
Craig Mathews' brilliant caddis emerger pattern sits in the surface film, imitating a caddis struggling to break through the meniscus. Deadly during caddis hatches when fish refuse higher-riding patterns. The trailing shuck is key to its effectiveness. The X-Caddis fills a critical gap in the caddis life cycle that most fly boxes lack. While traditional dry flies like the Elk Hair Caddis ride high on the surface, the X-Caddis sits flush in the film with its body partially submerged and a trailing Z-lon shuck extending behind. This precisely imitates the moment when a caddis pupa breaks through the surface and begins to shed its pupal shuck, the most vulnerable stage for the insect and the moment when trout feed with the least caution. On Montana's caddis-rich rivers, the X-Caddis can make the difference between a frustrating day of refusals and a banner day of steady action. When you see trout rising during a caddis hatch but refusing your Elk Hair Caddis, the X-Caddis is the answer. It is particularly effective on the Yellowstone during the Mother's Day caddis hatch, on the Madison during summer evening hatches, and anywhere trout have become educated to conventional caddis patterns.
