Rob’s Hellbender Nymph

Since we’re talking about big browns this month, I thought it only fitting to feature one of my favorite flies for big brown trout. While I have caught a number of big browns on small flies over the years, most of the big guys in the mountains have come on larger stonefly nymphs. This is a little bit misleading as most of the large browns I’ve caught in the Smokies I spotted before I fished for them. And when I spot a big brown trout, I almost always tie some sort of stonefly nymph imitation to my line. Who is to say I wouldn’t have caught those same fish on a #20 Zebra Midge had I chosen that fly?

I’ve always said that fly selection is 45% scientific, 45% experience, and 10% dumb luck. The scientific aspect comes in when you choose a fly to specifically imitate something that the fish are known to be feeding on. For example, if you see sulfur mayflies hatching, you see fish feeding on them, and you choose a sulfur mayfly imitation, you’ve more or less made a scientific decision. If you go to the stream and tie on a Royal Wulff for no other reason than you’ve always done pretty well on a Royal Wulff, you’ve made your decision based on experience. And of course, if you choose to fish the purple and green fly for no other reason than it looks neat, you’re pretty much depending on dumb luck!

All three methods have been successful over the years but the first two are usually more reliable because you have something at least somewhat logical and reliable to base the decision on. Even when your logic may be incorrect, such as choosing a sulfur to imitate a perceived sulfur hatch when the fish are actually eating caddis, you tend to have more success because you have confidence in your fly. When you have confidence in your fly pattern, you tend to fish it longer and better.

My tendency to select a stonefly nymph when I fish to a big brown trout comes from scientific reasoning and experience. I’ve studied the aquatic entomology of the Smokies and know that there are a lot of stonefly nymphs in the streams. I also reason that a larger morsel of food, like a stonefly nymph, would be more enticing to a larger fish. And I’m also relying on experience – I’ve caught a lot of big brown trout on stonefly nymphs over the years.

Golden Stonefly Nymph

Some of my favorite “go-to” stonefly patterns over the years have been old standards like a Tellico Nymph, a Bitch Creek Nymph, and a Girdle Bug. I always liked the coloring of the Tellico because I thought it best represented a golden stone, which seems to be the most prolific big stonefly in most Smoky Mountain streams. I liked the flat, two-tone profile of the Bitch Creek Nymph. It seems to produce a nice rocking motion on the drift. And while the Bitch Creek Nymph does incorporate rubber legs in the design, the additional rubber legs on a Girdle Bug always seemed to give it a much more lifelike appearance.

So what did I do? I took what I thought were the best features from each of my favorite stonefly nymph patterns and blended them into one fly. The result is Rob’s Hellbender Nymph. It has the flat, elongated, two-tone profile of a Bitch Creek, the multiple rubber legs of a Girdle Bug, and a color similar to the Tellico.

I weight these flies with lead wire that is flattened to provide that rocking motion in the water. I not only tie them in different sizes, usually #10 – #4, but I tie them in different weights. To get down fast in deep, fast runs, I like a lot of weight, but I prefer a lightly weighted one when casting to a brown trout in the shallows.

For whatever reason, offering flies in different weights tends to be too confusing to customers at a fly shop so commercially tied patterns like this one are typically made available in one uniform weight. So the ones you find in a shop like Little River Outfitters are going to be lightly weighted so the fly can be fished in slower, shallower water. To get them down quickly in deeper, faster runs, just add the appropriate amount of split shot.

While I may choose something like a large streamer when searching for big browns, this fly has become my “go-to” for a large brown that I have spotted first. Of course, every situation is different and there will be countless circumstances that suggest otherwise. But next time you’re in the Smokies with a big brown in your sights, see what he thinks about this bug!

Flies: Rob’s Hellbender Dry

As about anyone who knows me can tell you, I’m terrible at self-promotion. The worst. So it should come as no surprise that I’ve never featured one of my own patterns in the newsletter. Usually I opt for more standard or classic patterns. But this is a good fly and it’s good this time of the year, so here you go!

I started tying this one probably 4 or 5 years ago, and if you’ve fished with me in the summertime or fall, you’ve probably fished with it at some point. Heck, you might have even caught a fish on it. It started as most fly patterns do for me, as a modification to an existing pattern. If you’re not a fly tyer or maybe if you’re new to it, you may not realize that fly tying is a lot like cooking. You can make up a recipe totally out of your head. You can follow an existing recipe step by step. Or you can take an existing recipe and modify it to better suit your taste. I’ve done all of the above over the years.

Just before this pattern was born, I was having success with a fly called a Neversink Caddis, a great little foam pattern named for the Neversink River in New York. But I got to thinking about a yellow foam body fly with a little flash. So I tied a Neversink Caddis with a little Krystal Flash under the wing. Then I thought about how great it would be to have a yellow foam body fly with a little flash and some rubber legs. So I tied a Neversink Caddis with a little Krystal Flash under the wing and rubber legs on the side. Then I started thinking about how well it might work if it was still buoyant, but rode a little flatter on the surface. You get the idea.

There comes a point where you change so many things about a chili recipe that it’s no longer chili. And after the fourth or fifth modification on this fly, it was no longer a Neversink Caddis. It was it’s own fly and it was catching fish. A lot of them. I was fairly quiet about it but had more than a few guide clients that started asking for the fly at Little River Outfitters, and it wasn’t long before Daniel asked me to tie some for the shop.

Bottom View

I’ve done some commercial tying in the past and it’s a grind – a whole lot of work for not much money. I remember when I first started fly fishing, I’d go to a fly shop and say, “Seriously? They charge $2 for one of these?!?” After I began tying commercially, tying hundreds of dozens of flies, I remember saying, “Seriously? They only charge $2 for one of these?!?” Needless to say, I wasn’t jumping at the chance to get back into the commercial tying game.

So I went a different route and submitted it and another nymph pattern to a large fly distributor. If accepted, you send samples with tying instructions, they mass-produce them, and you collect a royalty for each dozen sold. Pretty neat. It doesn’t add up to much but I collect a check at the end of each year that’s enough to take my wife to a nice dinner. I have other original patterns that I keep intending to submit but never seem to get around to it. Maybe this winter.

So that’s how the fly came to be. It’s a good fly pretty much anytime between late April and early November, but I like it best in the late summer and early fall when the water is low. In low or flat water, high-riding, bushy flies get refused a lot, and I have trouble keeping more sparsely dressed flies afloat. But Rob’s Hellbender floats great, sits lower and flatter on the surface and seems to produce strikes when its high-riding counterparts fail.

It falls under the attractor category, as it doesn’t really imitate anything in particular. I’m sure it mostly gets taken as a stonefly or hopper. Either way, they eat it and you need some. If you want to tie it, the recipe is below.  Or better yet, buy a bunch at Little River Outfitters so I can take my wife out to dinner.

Flies: Red Fox Squirrel Nymph

Even with all the newfangled fly patterns and fly tying materials available today, I usually find myself sticking more with the old staples, or at least pretty similar variations. And I stick with them for one main reason: They work! Created by fly tying guru, Dave Whitlock in the 1960’s, this fly definitely falls under the “old staple” category.

As disappointing as this may be to some, the fly was not named for Redd Foxx of Sanford and Son – you big dummy! Rather, it got its name for the simple reason that it is tied mostly from the fur and hair of a red fox squirrel. It is considered an impressionistic fly, meaning that it is designed more to look alive or “buggy” more than imitating a specific food source. We also lump these sorts of flies in the categories of “attractors” or “generals.” Or Orvis likes to call them “prospecting flies.”

So really, it’s a pretty good fly to fish anytime in the Smokies, but I think it is at it’s best in the early spring. I attribute that to the abundance of Quill Gordon nymphs in the water at that time, as this impressionistic fly imitates that nymph as well as any other I’ve fished. I’ve had a lot of success with the traditional, light red version of this fly, but tie them in a few other colors as well. Different colors might better imitate other food sources in the water, but may also better imitate the color of Quill Gordon nymphs found in a specific river, or even a specific stretch of river.

Quill Gordon Nymph

It’s hard to say just how selective these trout can get and how important it is to match the color of the nymph, but I’ve personally found Quill Gordon nymphs in Little River that range from a light reddish color, to tan, to grey, to dark reddish brown, to olive. You can see that the Quill Gordon nymph in the picture has more of a dark reddish brown color. Though it’s probably more of a confidence thing, it seems that some years a certain color just works better than another.  I like to fish double nymph rigs with two different colored nymphs until I zero in on their preference.

In any case, these Quill Gordon nymphs are pretty robust, and the beefy body on the Red Fox Squirrel Nymph seems to suggest that better than, say, the slender profile of a Pheasant Tail Nymph. And the picked-out fur body and soft hackle provide a lot of subtle, life-like movement.

Hare’s Ear Nymph

A close cousin to the RFSN, is the Gold Ribbed Hare’s Ear Nymph. This is another one of those staple flies that is really simple to tie and can be found in most any fly shop.   I will sometimes fish these in a tan or olive color as an alternative to the RFSN or even in tandem in a two nymph rig.

In all cases, I’m usually fishing these flies in fairly large sizes – typically in the #14 – #10 range. As the season progresses, I’m more likely to fish them in smaller sizes and lighter colors. They can be purchased or tied in beadhead or non beadhead versions. The non beadhead will typically have lead wire wrapped around the hook under the materials. I personally like the look and profile of the beadless version better. But that’s just one man’s opinion. Try them both and tell me what you think!

Below is Dave Whitlock’s original recipe for the nymph.  I fish the beadhead version most, and I tend to substitute commercial dubbing for the mixes he describes below.

Flies: Quill Gordon Hatch

March is the month when trout fishing in the Smokies officially kicks off. Days are getting a little longer, temperatures are getting a little warmer and water temperatures are on the rise. It’s also the month when we begin to see our first good hatches of the year.

Aquatic insects from Early Black Stones to Blue Wing Olives to a variety of midges will hatch all winter, but trout rarely pay much attention to them as water temperatures are typically too cold for active feeding (read Understanding Water Temeratures for more info). But in March, that begins to change. And if you pay attention to water temperature, you just might catch one of the best hatches of the year.

Quill Gordons are fairly large mayflies, between a #14-10 hook size, that begin to hatch when the water temperature reaches 50-degrees for a significant part of the day, for a few days in a row. In unusually warm years, they’ve hatched as early as mid February. In particularly cool years, they may not hatch until April. But most years on the lower elevation streams in the Smokies, this occurs about the third week of March.

In any case, it’s a tricky hatch to catch and really just a tricky month to fish if you don’t live here where you can pick your days. Weather can change in the blink of an eye in March and one major cold front or one big, river blowing rain can make all the difference in your success. I’ve had some of my absolute best days in March and I’ve had some of my worst.

So, why even fool with it? Why not just wait until April when things are more stable? Because some of those “best days” were really, really good! The Quill Gordon hatch is not just worthwhile because of the number of bugs or the size of the bugs. It tends to happen at the exact same time wild mountain trout begin actively feeding. Many of these trout, including the large browns, have had very little to eat in the last 2-3 months and they tend to be a little less cautious. And when a size #12 Quill Gordon comes drifting down the lane, well, it’s pretty hard to resist!

Brown trout exceeding 20” don’t get caught very often in the Smokies, period. Even fewer are caught on dry flies. I’ve been fortunate to catch a fair number of large browns on dry flies in the Smokies, and probably 99% of them have come during the Quill Gordon hatch. Though it’s certainly a gamble, THAT is why it’s worth coming in March!

The good thing about the hatch is once it starts, it usually doesn’t stop. So, if the hatch gets started on say, 3/21, they’ll keep hatching every day even if you get a significant cold front on 3/25. While such a cold front may not impact the hatch, it still might impact the way the trout feed, and they may be more reluctant to come to the surface. What many people forget, is that for all the bug activity on the surface during a hatch, there is just as much, if not more, activity under the surface with nymphs preparing to hatch. Drifting a greyish olive nymph below the surface can also be very productive during this hatch, especially in colder water

Most years the hatch lasts 2-3 weeks and it is usually at its best during the warmest part of the day. In March, that’s typically about 11am to 4pm so rearranging your lunch plans is not a bad idea.

The best place to be during the hatch is in a larger pool near the head and middle of the run. Unlike most other instances fishing the Smokies, this is a time when you may need a little more distance on your cast and your mending skills will be put to the test. The fish may be more aggressive but they still won’t tolerate a bad drift!

Flies: Quigley Cripple

Okay, so it’s not exactly the most politically correct name for a fly pattern. Maybe the Quigley Emergently Challenged Mayfly would be a better choice? Nevertheless, as teased in the newsletter text, it has been a “hatch buster” for me since probably the early 90’s. The fly has been around a little longer than that, devised by Bob Quigley in the late 1970’s.

What do I mean by hatch buster? Some hatches of aquatic insects can get so heavy and last for such long periods of time that trout become ultra selective on the flies they eat. They just have so many of the naturals available that your fly, no matter how precise an imitation, can kind of get lost in the mix. We have few hatches of that magnitude in this area but when we do, it’s usually going to be a sulphur mayfly. They can come off fairly heavily in the mountains in May, particularly late in the day. We also see significant hatches of them on area tailwaters, particularly the Clinch and South Holston. On the Clinch, it’s usually from late April through early July and on the South Holston, they come off nearly nine months out of the year!

The Quigley Cripple looks a bit of a mess, but that’s kind of what it’s supposed to look like. During the emergence process, there’s a period of time when the adult mayfly is attempting to break free of its nymphal shuck. It usually occurs right in the surface film and it usually only takes a couple of seconds. However, this is a highly vulnerable couple of seconds. You can’t run with your pants down! Sometimes they’ll get stuck in this stage even longer, particularly on damp or even overcast days.

In either case, trout will often key in on the insects that are in this stage as they are such easy targets. In many cases during a heavy hatch, you’ll find trout that feed exclusively on bugs in this stage, ignoring adults and nymphs. Needless to say, if you don’t have a fly that imitates this, you could be missing out on a lot of trout!

There are a number of patterns that are intended to represent this stage of a mayfly’s life, but I have had more success with the Quigley than any other. The brown tail and “abdomen” of the fly suggest the case of the nymph while the yellow “thorax” suggests the adult half out of the case. The deer hair and hackle represent the wings and legs of the struggling adult.

It sits pretty low in the surface film. As a matter of fact, I often apply floatant to only the thorax and wing so that the fly will rest sort of half above and half below the surface film. Because it sits so low, it can be a little difficult to see. My favorite way to fish it is as a dropper, about 18” behind a more visible parachute or comparadun dry fly pattern. Having the higher riding dry fly as reference allows me to better see the cripple. Even when I can’t see it, if I see a trout rise within 18” of my dry fly, I assume he’s hitting the cripple and set the hook. Great fly, give it a try!

Skills: Fishing High Water

The Smoky Mountains are known for receiving large amounts of rain in a season and when it comes in bunches, the result can be swollen, rough, intimidating, and dangerous streams and rivers. Good and bad things occur when the water rises in mountain streams. On the down side, the streams become much more dangerous and sometimes impossible to wade. The faster current also makes it more difficult to control your drift. On the up side, a lot of food gets churned up in the stream, and that factor, combined with a level of comfort and security in stained water, often results in more reckless feeding by some of the bigger trout on the block. There are brown trout exceeding 20” in many mountain streams that don’t get caught often, but when they do, it’s usually when the water is up and off color.

The stream is going to look completely different under these conditions and it will help if you have intimate familiarity with the stream under normal flows. Regardless of how well you know the water, always use extreme caution under these conditions and don’t try any heroic stream crossings. One wrong step can quickly get you in big trouble! In fact, it’s not a bad idea to wear a life vest when fishing under these conditions. Better safe than sorry!

Forget about finesse. You’re not going to coax rainbows to #16 dry flies with delicate casts. Bring a long rod for a heavier line – maybe a 9’ 6 weight – and plan on chucking large, heavy nymphs with a rosary of split shot and no strike indicator. Casting is going to simply involve one flip behind you, wait for the tug on the rod tip, and chuck it forward with an open loop. Long casts are not necessary and will be less effective.

Instead, wade the edges and look for slower seams on the edge of fast currents and eddies behind rocks. Position yourself as close to the feeding zone as you safely can and use the length of the rod to reach and hold your flies in position. Keep the rod tip up and try to keep as much of the fly line off the water as possible, allowing for a much slower, more controlled drift. Follow the flies with the rod tip as they drift through the feeding lane and keep an eye on the fly line between the rod tip and water. You may feel a strike since you’re working with such a short line but most likely you’ll determine the strike when you see the fly line pull down or hesitate. If anything suspicious like this occurs, set the hook! With practice you’ll soon be able to differentiate between fish and rocks.

Don’t expect to catch large quantities of fish under these circumstances. It will be tough fishing to say the least. But if you stick with it, the rewards can be enormous!

Flies: Madame X

A good fly pattern is a good fly pattern. And while many good fly patterns, for one reason or another, may fall from popularity, it’s not because they stop catching fish – they just stop catching fishermen. The Madame X certainly fits that description as it had tremendous popularity twenty years ago but is rarely mentioned today.

I became reacquainted with this fly about a month ago on a rare day off, fishing upper Little River with a couple of old friends. I was fishing a nice stretch of pocket water that had a few pools mixed in and was having moderate success when I noticed a large (about a size #8) golden stonefly in the air. These primarily hatch at night but there are always a few holdovers and they’re such a big meal, I think trout are often still looking for them the next morning. So, sometimes their imitations can still work well, even when they’re not hatching.

When I began searching my box, I came across a few Madame X’s that had probably been in my box, unfished, for about 15 years. They fit the size and color profile I was looking for and sometimes I just enjoy going “retro” and fishing forgotten flies from days gone by. I figured at the very least, a big stonefly imitation would be a great, buoyant dry fly to fish with a nymph dropper. So, I dropped a little Pheasant Tail variation about 15” off the back, expecting it to account for any fish caught.

On the first cast into the first pocket, a fish exploded on the #8 Madame X! It surprised me and I missed the strike. On the second cast, the fish hit it again and I was ready that time – a solid 10” rainbow. This continued in nearly every pocket of water I fished. I caught dozens of chunky rainbows and probably 80% of them came on the big Madame X.

Doug Swisher originated this pattern in the 1980’s as sort of a multi-purpose attractor pattern to be fished on his local waters in Montana. Mostly it was believed to represent a large stonefly adult or hopper. Over the years, it was frequently modified in size and/or color to represent a number of large bugs but somehow seemed to fall off the radar after the mid to late 90’s. Many fly tiers began using foam for large flies around that time and I suspect the Madame X just fell out of style.

Well I’m here to tell you that there are plenty of trout that still think it’s cool and I have been fishing it a little more regularly lately. I don’t know if the trout take it as a stonefly or a hopper, and I honestly don’t care. They take it! I fish it mainly with a yellow body but I’m sure other colors would work. And I fish it mainly in sizes #12 through #8.

Flies: Lime Trude

Summer is creeping slowly into the Smokies and fly patterns are beginning to shift again. In late spring and summer, nearly everything that hatches is brighter in color. Most of the aquatic insects you see are some shade of yellow or bright green, so it certainly makes sense to fish fly patterns in the same color profile.

As I’ve mentioned numerous times, fly patterns are hardly the most important piece of the puzzle when trout fishing in the Smokies. Approach and presentation is the name of the game here. The wrong fly presented well will always catch more fish than the right fly dragging across the surface. But if your presentation is solid, it stands to reason that showing the trout a fly that looks a little more like the naturals they are seeing will produce far more strikes.

Since hatches in the Smokies are rarely heavy enough to make the trout key in on specific insects, color and size are really the most important components of fly selection. And since we tend to fish a lot of riffles and pocket water in the summer months, buoyancy and visibility can be extremely beneficial as well. While there are a number of fly patterns that meet all of those needs, one of my favorites is the Lime Trude.

The Lime Trude is just one of many variations of what was originally a wet fly designed by Carter Harrison. In the early 1900’s, on a trip to the A.S. Trude Ranch near Big Springs, ID, the fly was apparently created as a joke, using red yarn from a cabin rug as the body and reddish dog hair for a wing. The fly was an instant success and eventually got “dressed up” with more common fly tying materials, including a tail and hackle, converting it to more of a dry fly dressing.

The fly became a staple in the Rocky Mountains and evolved, as most patterns do, with the increased availability of more diverse fly tying materials. It seems a number of great fly tiers, including Dan Bailey, had a hand in the evolution of the fly we know today. While there are a number of variations still available, the Royal Trude is probably the best known. Essentially, it is just a hair wing version of the classic Royal Coachman. The Lime Trude, which gained notoriety after winning the Jackson Hole One-Fly Contest (I believe in the late 80’s or early 90’s), is probably a close second in popularity.

Much of the fly fishing history in the Smoky Mountains was not recorded so it is difficult to say just when the fly first made an appearance on our streams. But it has certainly been catching trout for many decades. For the purposes mentioned above, it has everything you need. The bright, greenish-yellow body looks like a lot of what the trout see this time of year. The hackle and calf wing make it a fairly buoyant fly. And the white hair wing also makes it highly visible.

It is certainly an attractor fly that might pass for a variety of caddisflies, stoneflies, and even mayflies. Fish it in sizes #16 – #12 on your favorite Smoky Mountain stream and let me know what you think!

Flies: Isonychias

The mayfly with the funny name is one worth knowing when it comes to fishing in the late summer and early fall. Actually, all mayflies have funny names, but most, over the years, have become known by some common name such as Light Cahill, Sulfur, March Brown, or Quill Gordon. But the Isonychia still proudly boasts its Latin name. Sure, there are those who might refer to them as Mahogany Duns, Slate Drakes, or even Leadwing Coachman, but none of those names ever stuck.

Isonychia Nymph

Probably the main reason is that those common names refer more to this insect in its adult stage, but to the trout (and trout fisherman), the nymph is by far the most important stage of this insect’s life. Isonychias, or Iso’s as some call them, don’t behave like most other mayflies when they hatch. Most mayflies will emerge to the surface and hatch in the water near the surface film. After hatching, they are often on the surface for a small amount of time, allowing their wings to dry before they fly off. This leaves most mayfly adults vulnerable to hungry trout and is the stage of the lifecycle that many dry flies represent.

But Iso’s behave more like a stonefly in that the nymphs swim to rocks or woody debris and hatch out of the water, with the trout never getting a shot at the adult until it later returns to lay eggs. Take a closer look at exposed rocks in or around the stream this time of year and you’ll likely see some of their empty shucks.

In the Smokies, they typically hatch from August through October with peak emergence in September. If you want to try your luck imitating them with dry flies, try a dark bodied parachute in size #14-12. The body color will typically be anything from a deep mahogany to dark grey or even black. A good ol’ Parachute Adams is probably as effective as anything. When they return to the water to lay eggs (known as the spinner stage), their body color is more orange or rusty.

George Nymph

However, as mentioned above, the nymph is what you should be most concerned with. Also in sizes #14-12, the nymph is slender with a dark brown to black body with a very distinct white stripe down the back. You will sometimes find specific Isonychia nymph patterns but they are also imitated well with such common patterns as Prince nymphs or Zug Bugs. The late Eddy George was a well-known and highly respected fisherman and fly tyer in this area. He is probably best known for the George Nymph, a fly that I regularly tie and fish in the Smokies. Many people speculated what this fly might represent but with its slender, dark body and white poly-yarn back, it’s incredibly effective during Isonychia time!

Dark soft-hackled wet flies are very productive, too, as Isonychias are active swimmers and tend to be most active in the mornings and evenings. Any time of day is a good time to drop one of the above fly patterns off a dry fly. Early and late in the day, try fishing with one or a pair of these nymphs and vary your typical dead-drift presentation to offer the occasional twitch or even swing. Check out the “Active Nymphing” article in this newsletter for more on that presentation.

Flies: Griffith’s Gnat

Griffith’s Gnat

Colder months don’t allow for much in the way of dry fly fishing in East Tennessee. As a matter of fact, when the water temperatures are down in the 30’s, it can be tough enough catch fish on nymphs. But in early March, and during occasional warm stretches in January and February, water temperatures can climb just enough to produce a hatch.

Sometimes in these conditions, particularly on sunny days, bugs may start hatching but fish still opt not to expend the energy to feed on the surface. But there are often isolated areas, mostly slower pools, where they do feed rather methodically on the surface and I just can’t pass up the opportunity to catch a fish up top!

There are a variety of insects that are likely to hatch at these times. The most common are black caddis, black stoneflies, black midges, grey midges, and Blue Wing Olive mayflies. There’s not a lot of rhyme or reason to what exactly might be hatching, or which bug the fish might be keying in on. And with the dry fly fishing being so sporadic and unreliable at that time of year, for most, it doesn’t make a lot of sense to buy/tie a bunch of these patterns and carry them on the stream. Most will likely just end up rusting in your box!

Adult Midge

However, what these insects all have in common is they’re dark in color and small in size – mostly #18 and smaller. The Griffith’s Gnat is a small, dark dry fly originally designed to imitate a midge, but it is generic enough to effectively imitate all of the above insects in most situations. So, rather than carrying four different sizes of six different fly patterns, I tend to carry Griffith’s Gnats in sizes #18 – #22 and am able to fool all but the most selective of trout (and a few of them, too). As a matter of fact, I once fished a heavy Blue Wing Olive hatch where the fish were actively feeding on the surface. There were many fish that were refusing the actual Blue Wing Olive imitations but were eating the Griffith’s Gnat!

It’s just one of those “must-have” flies that I always have in my box, and not just in the winter. It makes for a pretty effective ant imitation during the summer and is a great year round dry fly on tailwaters where midges hatch almost daily. Pretty much, if the fish are feeding on something small and dark, you’ve got more than a fighting chance with this fly.

There are always exceptions, but mostly I fish this fly on a dead drift, typically with a longer leader and smaller tippet, usually 6X. For a small, dark fly, it’s pretty visible so I often fish it by itself. But in choppier water, in tougher light conditions, or when I just want to give fish options, I will tie it as a dropper off the back of a slightly larger and more visible dry fly. If I tie it 18” off the back of a Parachute Adams, and I see a rise anywhere within 2’ of that Adams, I set the hook.

If you tie your own, it’s a really easy fly to tie. It was always one of the first flies I’d teach when I was teaching beginner fly tying classes. Or if you buy your flies, you can find them almost anywhere. Give it a try!
