Prince Nymph

The Prince Nymph is one of the most versatile and productive attractor nymphs in fly fishing history. Originally tied by Doug Prince in the 1930s and later refined by Buz Buszek, this pattern has become a staple in fly boxes across North America. Its distinctive appearance, featuring peacock herl, white biots, and soft hackle, makes it an irresistible offering to trout in nearly every water type. What makes the Prince Nymph so effective is its dual nature as both an attractor and an imitator. The peacock herl body creates an iridescent sheen that catches fish attention, while the white goose biot wings provide a striking contrast that fish can see in turbid or stained water. The brown hackle gives the fly lifelike movement in current, breathing and pulsing with every drift. While it doesn't precisely imitate any single insect, it suggests stonefly nymphs, caddis pupae, and various other aquatic insects that trout feed on regularly. The Prince Nymph excels in freestone rivers and streams where stoneflies and caddis are prevalent. Its dark profile makes it particularly effective in pocket water, runs, and riffles where trout hold in current breaks waiting for drifting nymphs. The fly works well as both a searching pattern when you're not sure what fish are eating, and as a proven producer during general mayfly and caddis activity. Many anglers use it as the lead fly in a two-nymph rig, paired with a smaller midge or mayfly pattern. One of the Prince Nymph's greatest strengths is its effectiveness across seasons. In spring, it imitates the early stonefly nymphs beginning to move toward shore. Throughout summer, it serves as a general caddis pupa imitation. In fall, when larger insects are still active but cooler water makes fish more selective to subsurface presentations, the Prince continues to produce. Its versatility extends to various water types, from small mountain creeks to large tailwaters, making it an essential pattern for any fly fisher's arsenal.

Technique & Presentation

The Prince Nymph is an excellent pattern for beginning tiers, though achieving the classic proportions requires attention to detail. Start by securing forked brown goose biots for the tail, ensuring they split at roughly 45 degrees. The tail should extend about half a shank length beyond the bend. Wrap three to five peacock herls together for a robust, durable body, and counter-rib with fine gold wire to prevent the fragile herl from breaking.

When adding the white goose biot wings, the key is proper placement. The wings should be tied in at the thorax area, standing upright at approximately 45 degrees, with tips extending just past the hook eye. Many tiers struggle with keeping the wings symmetrical—using a tight thread wrap and positioning the biots on opposite sides of the shank before securing helps maintain even spacing. After tying in the wings, wrap brown hackle just behind them, making two to three turns for smaller sizes and three to four for larger flies.

Fishing the Prince Nymph effectively requires understanding weighted versus unweighted versions. For fishing deep runs and pockets, tie the pattern with lead wire underbody or use a tungsten bead head version. In shallower water or when fish are feeding higher in the column, an unweighted Prince dead-drifted through riffles can be deadly. The fly works exceptionally well as an anchor fly in Euro-nymphing rigs or as the top fly in a standard indicator setup with a smaller nymph or emerger trailing behind.

Presentation varies by water type. In pocket water, cast upstream and allow the fly to sink quickly into the feeding zone. In runs and riffles, quarter your cast and mend to achieve a drag-free drift. Watch for subtle takes—often fish will inhale the Prince confidently, but in pressured waters, strikes can be tentative. A slight hesitation in the indicator or a barely perceptible pause in the line often signals a fish. Set the hook with a smooth strip-strike rather than a violent lift to avoid breaking off on larger trout.

History & Origin

The Prince Nymph traces its origins to the 1930s when Doug Prince, a California fly tier, created the original pattern. Prince's innovation was combining peacock herl with forked goose biots in a way that suggested multiple aquatic insects without precisely imitating any single species. The pattern remained relatively obscure until Buz Buszek, a noted Colorado fly tier and publisher, encountered it in the 1940s and began promoting it through his catalogs and publications.

Buszek's modifications to Prince's original design included standardizing the brown hackle collar and refining the proportions to create the pattern we recognize today. He featured it prominently in his fly-tying materials catalog, and the pattern quickly gained popularity among Colorado anglers fishing the state's productive freestone rivers. By the 1960s and 1970s, the Prince Nymph had spread throughout the Rocky Mountain West and beyond, becoming a fixture in fly shops nationwide.

The pattern's enduring success lies in its attractor qualities combined with suggestive realism. Unlike precise imitations that work only during specific hatches, the Prince Nymph produces consistently because it triggers feeding responses based on size, movement, and general appearance rather than exact mimicry. This versatility has led to countless variations, including bead-head versions, rubber-leg variants, and color adaptations, but the original brown and peacock combination remains the most trusted and widely fished version across North America's trout waters.

Pheasant Tail Nymph

Frank Sawyer's classic nymph pattern imitates a wide range of mayfly nymphs. The pheasant tail fibers create a realistic segmented body. Effective year-round in sizes #14-20, this pattern belongs in every Montana fly box. The Pheasant Tail Nymph is the most important subsurface fly in the history of fly fishing. Frank Sawyer's original design used nothing but pheasant tail fibers and copper wire, with no thread, no dubbing, no synthetics. The result was a slim, naturally segmented nymph that sinks quickly and perfectly imitates the profile of a swimming or drifting mayfly nymph. Modern variations have added a bead head for extra weight and flash, making an already deadly pattern even more effective. In Montana, the bead head Pheasant Tail is a year-round producer on every river in the state. It matches Baetis nymphs in fall and spring, PMD nymphs in summer, and various mayfly species throughout the seasons. Whether fished as a trailing nymph behind a dry fly, in a two-nymph Euro-style rig, or under an indicator, the Pheasant Tail consistently catches fish. Its slim profile sinks quickly and looks natural even to the most selective trout on the Missouri and Bighorn tailwaters.

Zebra Midge fly pattern

Zebra Midge

A devastatingly simple midge pupa pattern. Thread body with a bead head, and that's it. The Zebra Midge is the most effective winter pattern on Montana tailwaters and produces year-round on the Missouri and Bighorn rivers. The genius of the Zebra Midge lies in its simplicity. A small bead head, a thread body wrapped in even turns to create segmentation, and perhaps a few fibers for a collar, and that is all there is to it. Yet this pattern imitates the midge pupae that comprise an enormous percentage of a trout's diet on tailwater rivers. Midges hatch every day of the year on rivers like the Missouri and Bighorn, and the Zebra Midge matches them with astonishing effectiveness. The pattern's versatility is remarkable. Fished under an indicator in the classic dead-drift presentation, it produces fish consistently. But the Zebra Midge is also deadly when fished in the surface film as a midge cluster or suspended just below the surface on a greased leader. On winter days when other patterns fail, a small Zebra Midge in #18-22 fished deep and slow can save what might otherwise be a fishless outing. It is the great equalizer, the fly that always works when nothing else does.

Prince Nymph

A classic attractor nymph with peacock herl body and white biots. The Prince Nymph doesn't imitate any specific insect but suggests many. It's a reliable searching pattern when drifted through riffles and runs on all Montana rivers. The Prince Nymph occupies a unique space in fly fishing; it is perhaps the most effective attractor nymph ever designed. The combination of a peacock herl body, white goose biot wing, and brown hackle creates a fly that doesn't precisely match any natural insect but somehow suggests dozens of them. Trout see the Prince Nymph and recognize it as food, plain and simple. The iridescent sheen of the peacock herl, the contrasting white wings, and the buggy profile all contribute to its universal appeal. In Montana, the Prince Nymph is a workhorse pattern that produces fish from the first runoff of spring through the cold days of late fall. It excels as a dropper behind large dry flies, as a searching nymph under an indicator, and as a point fly in a two-nymph rig. On the Madison, Gallatin, and Yellowstone rivers, the Prince Nymph consistently produces when conditions are changing, hatches are unclear, or fish seem unwilling to commit to specific imitations. It is the problem-solving nymph that every angler should carry.

Pat's Rubber Legs fly pattern

Pat's Rubber Legs

A large, heavily weighted stonefly nymph pattern. Pat's Rubber Legs is the go-to point fly for nymph rigs on the Madison, Yellowstone, and Gallatin rivers. The rubber legs pulse with every micro-current, driving trout wild. Pat's Rubber Legs is the definition of a workhorse nymph. This large, heavily weighted stonefly imitation serves as both an effective fish catcher and the anchor fly in a multi-nymph rig. Its weight gets the entire rig down to the bottom quickly, while its rubber legs provide continuous movement that attracts trout from a distance. The variegated chenille body suggests the mottled coloring of natural stonefly nymphs, and the overall profile matches the large Pteronarcys and Hesperoperla nymphs that inhabit Montana's freestone rivers. On the Madison, Yellowstone, and Gallatin rivers, all premier stonefly streams, Pat's Rubber Legs is arguably the most important fly in a guide's box. It produces fish 12 months of the year, not just during the stonefly emergence. Stonefly nymphs are always present in the drift, dislodged by current, wading anglers, and their own movements. A large Pat's Rubber Legs drifted along the bottom is a convincing imitation that trout eat with confidence. Pair it with a smaller trailing nymph like a Pheasant Tail or Lightning Bug for a devastating two-fly rig.

San Juan Worm fly pattern

San Juan Worm

Love it or hate it, the San Juan Worm catches fish. This simple chenille or micro-tubing pattern imitates aquatic worms that are a significant food source in tailwater rivers. Particularly effective on the Bighorn and Missouri after rain events. The San Juan Worm divides the fly fishing community like no other pattern. Purists dismiss it as barely qualifying as a fly, while pragmatists point to its undeniable effectiveness and the scientific reality that aquatic worms (Oligochaeta) constitute a meaningful portion of trout diets, particularly in tailwater environments. On the Bighorn River, stomach sampling studies have shown that aquatic worms can represent up to 20 percent of a trout's diet during certain times of year. Regardless of where you fall in the debate, the San Juan Worm deserves a place in your fly box if you fish Montana's tailwaters. After rain events, rising water dislodges worms from the substrate and puts them into the drift, creating a feeding opportunity that trout exploit enthusiastically. Even during stable conditions, a San Juan Worm fished deep and slow on the Bighorn or Missouri can produce fish when more traditional patterns are not producing. The pattern is especially effective for large trout that have learned to target high-calorie food items with minimal effort.

Lightning Bug fly pattern
Nymph
springsummerfall

Lightning Bug

A flashy variation of the Pheasant Tail that uses tinsel and flash for added attraction. The Lightning Bug excels in slightly off-color water and as a dropper behind large dry flies. A Montana guide favorite. The Lightning Bug takes the Pheasant Tail Nymph concept, a slim, segmented mayfly imitation, and adds a generous dose of flash. The tinsel body and flashback wingcase catch light in ways that natural materials cannot, creating a beacon that attracts trout from greater distances. This makes the Lightning Bug particularly effective in off-color water, during overcast conditions, and in deeper runs where light penetration is limited. Montana guides keep Lightning Bugs in their boxes for those days when standard patterns are producing but not as well as expected. A switch from a standard Pheasant Tail to a Lightning Bug can turn an average day into a great one. The flash element seems to trigger a competitive or aggressive response in trout, prompting strikes from fish that might otherwise let a natural-colored nymph pass. On the Madison, Gallatin, and Yellowstone rivers, the Lightning Bug is a consistent producer from spring through fall.
