Trout fishing in autumn is indeed special. Something in the fish’s DNA prompts an urgency to pack on weight before the arrival of winter, when forage becomes harder to come by. And while the major hatches of the year are mostly past, there are still mayflies and caddis to bring big fish to the surface.

Of course, fall is also spawning time for browns and brookies. With their brightest colors in full display, they grow territorial as their instinct to reproduce awakens, along with a heightened aggression and a willingness to pounce on streamers stripped or swung past their lies.

There are myriad patterns to imitate insects, baitfish and other trout foods available in fall. Some anglers love to chuck huge, articulated streamer patterns in hopes of hooking a monster brown. Looking to take advantage of the last of the fishable hatches, such as Isonychias or October caddis, others stick to fishing bug imitations. Whether you prefer to target the big carnivores with large offerings or would rather stick with dries and nymphs for trout of all sizes, I offer five fly patterns that have consistently taken autumn trout for me.

1. ROYAL PMX

The Royal PMX (Parachute Madam X) is a marriage of two iconic patterns: Lee Wulff’s high-floating Royal Wulff and the rugged, versatile Madam X created by Doug Swisher. This hybrid attractor pattern combines a deer-hair wing, a body of peacock hurl and red floss, rubber legs and a parachute hackle wrapped around a highly visible white calf tail post. It’s like a one-man band, with features that suggest a wide variety of trout foods, from a grasshopper to a caddisfly to a stonefly.

Autumn is prime time for the Royal PMX as opportunistic trout feed on a variety of food sources. From late summer through mid-October, this pattern excels during warm afternoons on high-country freestones, pocket water and riffle-run tailouts where visibility and buoyancy are critical.

You can fish the Royal PMX several different ways, which makes it an incredibly versatile pattern. Fish it as a standard prospecting dry fly in pocket water and broken riffles, targeting areas near boulders, undercut banks and seams where trout hold. Its high visibility allows you to track the fly in complex currents and detect subtle takes.

It’s also the perfect anchor in a dry-dropper rig. Its excellent buoyancy supports even tungsten bead-head nymphs (like those listed below). Attach your dropper with 18 to 24 inches of 5X or 6X tippet for natural presentation, and drift the tandem rig along seams and cutbanks and in eddies where trout are looking for an easy meal.

Finally, slather the fly with flotant and twitch or skitter it across the surface to mimic a struggling terrestrial or stonefly or an egg-laying caddisfly. This is particularly effective near grassy banks where beetles, ants and late-season hoppers tumble into the water, as well as in the tails of pools.

Carry the Royal PMX in sizes 10 through 14, and fish them on sunny or windy days when terrestrials are most likely to end up on the water. The Royal PMX’s ability to suggest multiple food forms triggers aggressive strikes from pre-spawn browns and rainbows bulking up for winter.

2. OLIVE RS2

On the other side of the size and imitation spectrum is the RS2, which stands for Rim’s Semblance 2. Created by Colorado angler Rim Chung in the 1970s, this minimalist emerger pattern imitates mayflies and midges in that critical transitional phase between nymph and adult.

Blue-winged olives (BWO) hatch in both spring and fall, but the late-season olives are generally much smaller, so fish the RS2 in sizes 18 to 24. Because the fly is difficult to see on the water, tie it as a dropper behind a more visible indicator pattern, such as a Parachute Adams or one that features a fluorescent hot spot.

You can fish the RS2 on the surface or below it. If you’re casting to rising trout, their rise-forms can tell you where they are eating the olives. If you hear the trout break the surface and see clear, tell-tale rings with a few bubbles in them, the trout are eating insects off the surface. Put some flotant on the RS2 and keep it on top. If there are no bubbles, the trout are feeding in the surface film, so grease your leader but not the fly. If the trout barely disturbs the surface and you see little more than the hint of a fin, they are eating insects a couple of inches below the surface, so you should let the fly sink.

Fish the RS2 from midday to afternoon, particularly on overcast or drizzly days when blue-winged olives are most active. Try to dead-drift the fly directly to feeding trout, and use 5X or 6X tippet for a more natural presentation.

3. PURPLE TUNGHEAD HOT SPOT PHEASANT TAIL JIG

The Tunghead Hot Spot Pheasant Tail Jig is a modern version of the classic Pheasant Tail Nymph, incorporating innovations from competitive angling, like a heavy tungsten bead, a brightly colored “hot spot” to trigger strikes and a jig-style hook that rides with its point facing up to reduce snags. This has been my top-producing autumn nymph over the past three years, and it’s the pattern I tie on when nothing else is working. Cooling waters push trout into deeper runs and pools, and this fly’s tungsten bead excels at quickly reaching the strike zone.

Three presentation techniques dominate for fall fishing. Euro nymphing (tightline) represents the gold-standard approach, incorporating a 10- to 11-foot rod with a mono rig or Euro leader. The Tunghead PT Jig serves perfectly as your anchor fly, maintaining contact through seams, drop-offs and pocket water where autumn trout concentrate.

For larger rivers or when covering extended drifts, traditional indicator nymphing works beautifully. Rig the fly below a yarn or Airlock indicator using 5X fluorocarbon, pairing it with a smaller natural pattern like a midge or RS2 on a dropper.

When trout are sporadically rising, try a dry-dropper setup with the Tunghead PT Jig suspended under a buoyant pattern like a Chubby Chernobyl or Royal PMX.

Carry sizes 12 through 18, with orange or pink hot spots, which prove particularly effective in autumn’s lower light conditions and occasionally stained water. Fish the pattern ahead of approaching cold fronts or during warm afternoons whenever blue-winged olives and midges are active subsurface. Its slim profile, natural movement and quick descent make it especially deadly when trout are transitioning to deeper, cooler flows during fall.

4. BLACK TUNGHEAD ZEBRA MIDGE

As mayfly and caddis hatches become less frequent with fall’s progression, trout start to focus more on midges, which are always available. The Tunghead Zebra Midge balances simplicity with deadly effectiveness, especially in clear water. First popularized in the early 1990s on the San Juan River in New Mexico by guide Ted Welling, this pattern evolved from the original brass-beaded version to incorporate tungsten for faster sink rates in deep runs and swift tailwater currents.

The Zebra Midge imitates midge larvae and pupae—a primary food source for selective trout in nutrient-rich waters during fall months—and the tunghead version sinks very quickly so it stays in the strike zone longer. For standard indicator nymphing, fish the Tunghead Zebra Midge through deep pools, seams and tailouts where trout gently sip midges subsurface. This is also an excellent tag fly or even anchor in Euro-nymphing setups, as its slim profile cuts through the water quickly to reach trout in riffles and deeper glides. In shallow water or when fish are feeding near the surface, suspend the midge below a buoyant dry fly, like a Parachute Adams.

Carry this pattern in sizes 18 through 24, and fish it from mid-morning to mid-afternoon, especially after a frost lifts and during lulls between BWO hatches. If you’re not getting strikes, use your rod tip to impart subtle action to imitate drifting or rising midge pupae in slow runs.

5. TAN-AND-OLVE SCULPIN SNACK

Unlike bulkier streamers, the Sculpin Snack—developed by Pennsylvania angler and author George Daniel—features a slim, impressionistic profile that imitates sculpins and small baitfish and allows the fly to sink quickly and stay in the strike zone longer. It’s lighter than many fall streamers and doesn’t absorb a lot of water, which makes it easier to cast.

For optimal autumn success, focus on structure, such as cutbanks, logjams, deep pockets and undercut rocks, where sculpins naturally hide. Since sculpins are bottom dwellers, you want the fly right above the streambed, where it will draw the most attention.

Fish the Sculpin Snack on a floating line with a “sink-and-swing” presentation, a sort of streamer version of the classic Leisenring Lift. Cast directly across or slightly upstream, then throw a few roll-cast mends directly upstream of the tip of the fly line to feed slack into the drift. This allows the fly to continue sinking. When the tip of the fly line is 10 feet upstream of your target, start making short strips to pull the streamer off the bottom and swing it through the likely trout lie.

For clear water or slower stretches, try dead-drifting the pattern with occasional subtle bumps of the rod tip to mimic a stunned sculpin. In deeper water, a slow strip-pause-strip retrieve can be deadly.

Fish the Sculpin Snack on a 3X to 0X leader during low-light periods or on cloudy days. Remember that fall demands confident, aggressive presentations, so don’t hesitate to move the fly quickly to trigger reaction strikes from territorial trout.

Fall fishing is often less about matching a hatch and more about giving the trout something that suggests available food. These five patterns have become the basis of my autumn arsenal, so give them a try this season to bring more trout to the net.
