Caddis have always seemed to be one of the most overlooked and under-imitated aquatic insects in the fly fishing world. Maybe it’s because they haven’t been written about nearly as much as their sexier mayfly cousins over the years. I mean, mayflies are given names like Pale Morning Dun, Quill Gordon, and Gray Fox… just to name a few. Caddis are given names like Green Caddis, Brown Caddis, Black Caddis…
Regardless of the lack of respect given to caddis over the years, they have always been and continue to be abundant in nearly every body of freshwater and a staple in the diet of trout everywhere. I have numerous caddis patterns that I fish seasonally in the Smokies, but one that finds its way into the line-up more than any other is the Soft Hackle Wired Caddis.
There have been a number of wire body caddis patterns over the years and this is simply my variation on similar recipes. I sometimes tie it without a bead, but most often with a black tungsten bead at the head. It fishes well on a dead drift under a strike indicator but, especially when caddis are emerging, can be very effective fished with a drift and swing method. Learn more about this method and other similar techniques in this article on Active Nymphing.

I was shocked when I realized that I had never included an article about the Parachute Adams in this newsletter. Not only is it one of the best dry flies in the Smoky Mountains, it is arguably the best dry fly for trout in the world. It doesn’t imitate anything in particular but just has a buggy look and serves as a great “generic” mayfly imitation. In a pinch, it could also pass for a number of caddis and midges.
It is derived from the original Adams dry fly. A parachute pattern is merely a method of tying a dry fly. While traditional mayfly patterns had two upright and divided wings, with a hackle wound around the hook vertically; a parachute pattern has a single post with the hackle wound horizontally around that post. The post is typically white or some other bright color like pink or orange, allowing the angler to better see the fly on the water. Additionally, with a hackle wound horizontally around the post, the fly rides flatter on the water with a more realistic profile.
The original fly has been around for nearly 100 years. In 1922, Leonard Halladay, a Michigan fly tyer conceived the Adams as a general mayfly imitation. It was first fished by an Ohio attorney and friend of Halladay, Charles F. Adams on the Boardman River near Traverse City, Michigan. Charles Adams reported his success with the fly to Halladay who decided to name the fly after his friend. While it is unclear exactly when the Adams got the “parachute treatment,” parachute style flies began gaining popularity in the U.S. in 1971 when Swisher and Richards published the book, Selective Trout, and advocated the advantage of dry flies that rode flush on the water. One would assume that the parachute version of the Adams was born somewhere in that timeframe.
Since then, it has seen numerous variations in the body color, post material, post color and more. While many of these variations have been highly successful, it’s still tough to beat the traditional pattern. The recipe for that traditional version is included below.

When it comes to fishing dry flies in the Smokies, particularly on the smaller streams, I am typically looking for two primary things in a pattern: It needs to be visible and it needs to be buoyant. Beyond that I can begin focusing on a few more details like color and size.
In general, trout in the Smokies don’t see heavy hatches of individual insects. Rather, they mostly see small quantities of a lot of different insects. So, if you can present the fly naturally and without spooking fish, most any all-purpose, “prospecting” fly pattern will do the trick. As mentioned above, if you can get a little more precise with size and color, your pattern will be that much more effective.
Matching size will require more observation of bugs on the water or simply having general knowledge of what should be hatching. The same two things can help with matching color but also having broad knowledge of how seasons impact color can put you ahead of the curve. With some exceptions, aquatic insects tend to blend in with their surroundings. So, in winter months when trees are bare, most of what hatches is dark. As foliage comes in, most of what hatches is brighter.
The Stimulator has long been a favorite fly pattern of Smoky Mountain anglers for all of the reasons mentioned above. Its buoyancy and light colored wing not only make it easy to see, but make it a perfect “indicator fly” when fishing a dropper. And if you mix and match sizes and colors, you could nearly fish a Stimulator 12 months out of the year!
The Stimulator was long thought to be the invention of well-known West Coast angler and fly shop owner, Randall Kaufmann. While Kaufmann is responsible for the modifications that made the fly most of us know today, the fly’s true originator is thought to be Paul Slattery, who tied a stonefly pattern called the Fluttering Stonefly to fish on the Musconetcong River in central New Jersey. This was in the early 1980’s and he soon renamed the fly after a New York City punk-rock band called The Stimulators.
In any case, the fly seems to have been created to imitate an adult stonefly, but it is also a good suggestion of a caddis and sometimes even a hopper. I most often fish it in yellow and in sizes #16 – 8. I think the smaller size makes a great imitation for the prolific Little Yellow Sally Stoneflies, and the larger sizes are good representations of the larger golden stones that hatch on summer evenings in the mountains. In the fall, I often fish a #10 Stimulator in orange to imitate the large ginger caddis.
Whether it is imitating anything or not, it catches fish and it floats well in heavier pocket water found throughout the mountains. It is one of the most popular dry flies ever invented for trout and can be found in most every fly shop in the country.
In the Smokies, we are mainly fishing faster, choppier water and often choose bushier, more heavily hackled dry fly patterns that float well. In that kind of water, trout don’t get much time to study the fly and their view tends to be distorted by those choppy currents, so the bushier flies tend to do the trick. Even when fishing pools in the Smokies, you usually have a defined feeding channel that will have at least a little chop to it. In those situations, a parachute style fly pattern is usally adequate to provide a slightly more realistic profile.
But in flatter water like you commonly see on tailwaters like the Clinch, particularly weeks into a heavy hatch, an even more realistic profile is necessary. Trout routinely refuse parachute style flies and probably wouldn’t even consider a vertically hackled Catskill style dry fly.
This problem isn’t new to fly fishers. In the 1930’s, Fran Betters developed the Haystack to fool trout in slow moving spring creeks. It consisted of a deer hair wing and tail and no hackle, allowing for a lower riding fly with a much more realistic profile. Al Caucci and Ed Natasi introduced the Comparadun, a variation of the Haystack, in their 1972 book, Comparahatch. The pattern is essentially the same but they were able to use more modern microfibbets to create a longer, slimmer, more durable split tail that aided in floatation.
In the mid 1980’s, Craig Matthews and John Juracek took the Comparadun a step further and replaced the split microfibbet tails with a piece of antron or zelon. It essentially turned the fly into an emerger, with the antron or zelon “tail” suggesting the trailing shuck of an emerging mayfly. Of course, in any of the patterns described above, the body, wing, and tail/shuck colors can be altered to imitate different insects.
I routinely fish the split tail and the trailing shuck versions, usually during a sulphur or BWO hatch. And again, I am usually fishing them on the Clinch or possibly in a slow pool in the mountains. They just don’t float well enough to fish them in faster riffles and pocket water. But on a slow glide on the Clinch, they can be deadly!

Few fly fishermen, if any, possess the knowledge and experience of Joe Humphreys. Joe is probably best known as a teacher and an author, but over his many decades in the business, he has also created a number of original fly patterns. By far, my favorite is the Humphreys’ Caddis Pupa.
To be honest though, I’ve always been a little perplexed by the pattern. To me it bears little resemblance to a natural caddis pupa and doesn’t look like any imitation that I’ve seen or that I would create. In his book, “On the Trout Stream,” the only explanation Joe provides is “A good firsthand look at a caddis pupa prompted this tie.” Apparently Joe saw something in a caddis pupa that nobody else did, because his unique pattern has proven to be one of the most effective I’ve ever fished!
The body color can be varied to match caddis in a specific stream. I tie them often in olive and cream, but in the Smokies, most frequently find success with tan bodies. Some species of caddis hatches in the Smokies nearly anytime of year but the heaviest hatches tend to occur in spring.
It works best on any stretch of stream with more of a cobble or even sandy bottom. I frequently fish it as a dropper off a Neversink Caddis or in a tandem nymph rig below a soft hackle.

So, I’m writing about March Browns not because they are necessarily of great significance to the Smoky Mountain fly fisherman, but mainly because they’re just really cool bugs! Like many aquatic insects in the Smokies, this mayfly does not usually hatch abundantly enough to really get the trout keyed in on them, but it is worth keeping a few in your fly box. In other words, you probably don’t need fifteen different March Brown patterns in subtly different colors. Having a few of a basic pattern should do the trick.
March Browns are big, usually a #12 or #10 hook size, and they tend to be the first mayfly of the year with any color. Most of your early spring mayflies are some version of grey, but March Browns usually have a light, reddish brown body with handsomely mottled wings of brown, tan and even yellow hues. Contrary to what their name might imply, these mayflies don’t hatch in March. Rather, they tend to show up, at least in the Smokies, around the third week of April and hang around for the first half of May.
The nymphs are probably the most important stage for Smoky Mountain fishermen. While they have flat clingy bodies with muscular legs, making them very strong crawlers, when they lose their footing, they are terrible swimmers and easy pickins for a waiting trout. The nymphs tend to inhabit moderate to fast riffles and vary in color from tan to reddish brown to dark brown. A Hare’s Ear Nymph or Pheasant Tail Nymph are good generic imitations. I’ve also included one of my favorite patterns designed to specifically imitate a March Brown nymph.
Nymphing these patterns should be fairly effective all day but particularly early in the morning. Expect to see the adults hatching from late morning to early afternoon with a spinner fall near dusk.

Probably 20 years ago, I was fishing the Clinch River with a buddy during the sulfur hatch. I won’t get into what has happened to that hatch, but back then, it was epic. Sulfurs would come off by the thousands for 4-6 hours a day for about 3 months. We would drive down from Kentucky to fish it and on most trips, we would both steadily catch fish, many topping 20”.
On this particular trip, the bugs were coming off as good as they ever had, the water was boiling with rises, but we were both getting blanked! We were both going through every type of sulfur dry, emerger, and nymph in the box, all with the same result. Frustration got the best of both of us and we headed to the bank for a smoke, a bad habit we both enjoyed back then. While staring at the river and scratching our heads, it hit us both at the same time as we simultaneously exclaimed, “They’re eating caddis!”
Caddisflies tend to emerge quickly and almost explode off the water. When a trout feeds on one, it will frequently chase it to the top to eat it before it gets away. Sometimes the momentum will cause the fish to come completely out of the water, but at the least, results in a very distinct, splashy rise – not like the delicate sipping rise to a mayfly. Once we stepped away from the river and watched, we both noticed it.
We went back to the water and began looking more closely. Sure enough, there were caddis hatching, too. There was probably one caddis hatching for every 100 sulfurs, but for whatever reason, the trout were keyed in on the caddis. It’s what is referred to as a “masking hatch.” We both switched to the appropriate caddis pattern and were immediately into fish!
That’s not the only time something like that has happened, and each occurrence has trained me to always pay attention and sometimes try to look past the obvious. Here are a few things I’ve learned along the way that may help you solve a hatch riddle sometime.
First, we have to address the basics. If you see fish rising and have a pretty good idea what they’re eating but you’re fly is being ignored, check to see that your fly is the same size as the naturals. Also be certain that your tippet is not too large and that you’re getting a good drift. Presentation is most often the culprit when your fly is being ignored. Next, make certain that the color is a close match to the natural. If you’re fishing a bushy pattern, you might try a more subtle pattern like a Comparadun. If that’s not working, try an emerger fished just under the surface or in the film.
Still not catching them? Take a break and watch the water. You may be able to tell something from the rise rings as I described above. If you don’t learn anything from that, try to find a fish that is rising steadily and watch him. He’s probably feeding in rhythm, like every 10 seconds. Watch his spot and try to time his rises. When you have that down pretty close, try to see what he eats. You should be able to tell if it’s the same kind of bug you’re seeing in the air, or at the very least, whether he’s eating something on or just below the surface. It’s almost like detective work. You sometimes have to go through the process of eliminating suspects before you can zero in on your man!
If fish are actively rising but you don’t see any bugs in the air, check the water. Try to position yourself at the bottom of a feeding lane (downstream of where the fish are feeding) and watch the surface of the water (and just beneath) for drifting bugs. Holding a fine mesh net in the current is a great way to collect what’s coming down the channel, but if you don’t have one, your eyeballs will do just fine. If you see some insects, capture one and try to match it with a fly pattern.
Hatches are puzzles and that’s one of the things that makes them fun. Sometimes you solve it right away, sometimes it takes awhile. Just remember that while the fly pattern is a big part of the equation, it’s not the only one. As mentioned above, presentation is huge. In addition to your technique, a smaller tippet and/or a longer overall leader may be the solution. Also consider your approach.
While I typically like to cast upstream to fish so that I can stay behind them, they will sometimes shy away from your fly in slow runs if they see your line or leader. I will sometimes try to get above fish in slow runs and cast down to them so they are sure to see the fly first. You have to land your cast short of them with slack in the line, and feed slack to enable the fly to naturally drift to them. This is a challenging presentation and it is critical that you carefully position yourself out of the trout’s line of vision.
Again, it’s a puzzle and there’s not one universal solution to every challenge.
Pay attention to your technique and everything what you’re doing (or not doing). Most important, pay attention to the fish. They’ll usually tell you what to do!

If you take East Tennessee as a whole, it’s pretty safe to say one of the most prolific hatches is the sulphur mayfly hatch. Southern tailwaters are generally not known for having significant hatches of mayflies, caddisflies, or stoneflies. When we think of most of these dam-controlled rivers, we typically think of crustaceans like scuds and sow bugs, and midges…. lots and lots of midges. However, one mayfly that hatches on all East Tennessee tailwaters, often in very big numbers, is the sulphur. And that means that your best opportunity to catch a really big fish on a dry fly around these parts is during the sulphur hatch.
On the South Holston, they hatch in huge numbers for nearly nine months of the year. They hatch on the Holston, Hiwassee, Watauga and Caney Fork, too. But when I think of the sulphur hatch, I think of the Clinch River, probably because it was the first really BIG hatch I ever fished as a fly fisherman. And while it may not be quite as epic as it was 20-30 years ago, it is most definitely still a hatch worth making time for.
The hatch usually gets started in late April on the Clinch and often lasts well into July. May is the best time to fish it. In April, the bugs are usually just starting to trickle off fairly inconsistently. By mid June, trout have been seeing these things come off by the thousands for 4-6 hours a day, for 6+ weeks. To say that they become selective is an understatement. But in May, bugs are coming off steadily and the trout haven’t yet learned to count the hackles on your fly before choosing to eat it. They don’t seem to care if it’s on the surface, in the film, or 2” below the surface. In July, that stuff matters! In May, pretty much any pale yellow, size #16 dry fly will do the trick if it’s presented on a dead drift.
Parachutes and Comparaduns tend to be the best choices for dry flies. And there are a host of more sophisticated emergers and cripples to fool the wary, late-hatch fish. Pheasant Tails in brown and olive are usually the best option for nymphs.
While exact time and duration varies, the sulphur hatch on the Clinch typically starts in late morning and lasts for 4-6 hours a day, taking you right up to happy hour. Drifting Pheasant Tails will pass the time in the morning while you’re waiting for the main event to start.
Sulphurs are a big deal in the mountains, too. While they won’t come off in the obscene numbers found on the tailwaters, they are still one of the better hatches of the year. In the mountains, the hatch usually lasts 3-4 weeks and tends to be more of an evening event. Many nights, the sulphur hatch will correspond with the Little Yellow Sallies’ return to the water to lay eggs, making for a fast and furious end to the day for those willing to fish through supper.

April is one of the busiest months of the year for hatches and provides a smorgasbord of bugs for our finned friends. It’s also when we begin to see the change in color schemes on adult aquatic insects.
Aquatic insect adults are not only great sources of food for fish but also for birds. As a matter of fact, when you begin to see large numbers of swallows gather above the water and swooping down to the surface, it’s a sign for you to get ready because the hatch is beginning. Once the bugs have safely made it off the water, nature helps take care of them with appropriate camouflage to blend in with streamside trees and vegetation.
In the winter and early spring, most of your aquatic insect adults are black, grey, or some other dark color to better blend in with the dark, bare branches around the water. As we get later into spring and things begin to bloom, you begin to see more light- colored insects, such as tan and yellow. By the time summer rolls around, almost all of the adult insects are brighter yellows and greens to blend in with the abundant vegetation. And in the fall, you see more bugs with reds and oranges. There are of course plenty of exceptions to this but it’s a good guideline to follow with fly selection if you don’t know exactly what’s hatching.
So, April is a transitional month for color. Early in the month, we’re seeing the tail end of some of the darker bugs like Quill Gordons and Blue Quills, and by the end of the month we’re starting to see yellow bugs like Sulphurs and Little Yellow Sallies.
Most of the hatches in the early part of the month are sparse and can be covered with generic flies like a Parachute Adams. The first hatch of significance in April is the Little Yellow Sally stonefly. It is one of the most prolific hatches in the Southern Appalachian Mountains, beginning usually around the third week of April and lasting well into July.
Unlike mayflies and caddisflies, stoneflies do not hatch in the water. Rather, the nymph will crawl out of the water onto a rock before hatching. Pay attention when you are on the water, and you’ll probably notice empty stonefly cases on exposed stream rocks. This means that the adult stonefly is not nearly as important to the fly fisherman because the adults are not nearly as available to the trout. We focus more on imitating stonefly nymphs, and for dry flies, focus more on the adult when it returns to the stream to lay eggs. You’ll notice that many of the adult Little Yellow Sally imitations are tied with a red butt for that very reason – to imitate the egg layer.
Stoneflies are often large bugs but that isn’t the case with the Little Yellow Sally, as suggested by the name. These are commonly found in size #16 and are typically a very bright yellow, and sometimes chartreuse. They tend to hatch sporadically through the day and return to the water in the evening to lay eggs. Typically, the later in the hatch it is, the later in the day they will return to the water. So, in April, you may see them dive bombing the water to lay eggs in the early evening, while in late June, that’s probably not going to happen until almost dark.
There are a number of good imitations for the adult Yellow Sally. A yellow Neversink Caddis is one of my favorite “searching patterns.” For the nymph, you’ll want something tan to yellow in color. A small Tellico nymph or even a Hare’s Ear nymph should do the trick. And again, if you’re fishing when they’re laying eggs, something with a red butt can be very effective. Just plan to stay out late!

When many people think of fishing with flies, images of more familiar insects such as houseflies and mosquitoes are typically conjured. While some of these familiar terrestrial insects like ants, beetles, and hoppers are a source of food for trout, especially in the summer, it is aquatic insects that are most abundant to fish throughout the year and what most artificial flies are intended to resemble.
There are a number of aquatic insects in streams and rivers with mayflies, caddisflies, stoneflies, and midges being the most common. They are defined as aquatic because most of their life is spent in various stages in or on the water. The four groups listed above vary respectively in their life cycles, but are similar in that they begin in one form under the water, emerge and transform to another stage, and ultimately return to the water to lay eggs and start the process again. Let’s use a mayfly as an example.
First of all, the term mayfly is as general as the term flower. Just as there are many different flowers such as roses, daisies, and tulips, there are also many different mayflies such as Blue Wing Olives, Quill Gordons, and Sulfurs. And just as certain flowers bloom at specific, somewhat predictable times of the year, certain mayflies hatch at specific, somewhat predictable times of the year. Around here for example, you’ll usually see Quill Gordons in mid March, Sulfurs in May, etc.
The mayfly hatch that you hear about is technically the second time they hatch. A mayfly will first hatch underwater from a tiny egg into a nymph. The nymph is the juvenile stage of a mayfly’s life and it takes place entirely underwater. As a nymph, the mayfly has a very flat, streamline profile and typically lives beneath rocks on the stream bottom where it feeds on algae and such.
A typical mayfly nymph will live for about a year in this stage until it reaches maturity. At that time, the nymph will emerge to the surface of the water, a shuck splits open, and an adult mayfly (often called a dun) crawls out. The adult will be on the surface anywhere from seconds to minutes while it dries its newly formed wings before flying off to nearby vegetation.
With no mouthparts in this stage, the adult will usually not live for much more than a day so its sole purpose is to mate. After this occurs, the females will return to the water to lay their eggs until they finally lay spent on the water. So a mayfly’s only role in nature seems to be to feed trout.
But it’s not just trout that eat aquatic insects. Birds probably get the lion’s share and most aquatic insects are naturally camouflaged with this in mind. Understanding this can give you a leg up when it comes to fly selection, even when you don’t know what’s hatching.
In the very early and very late seasons when there is no foliage on stream side trees, aquatic insects need to blend in with the actual branches. Consequently, most everything that hatches during that timeframe will be dark in color (Gray, black, etc.). In the late spring and summer when foliage is full and vegetation is thick, most everything that hatches will be lighter in color (yellows, greens, etc.). And in the fall – you guessed it – most of the bugs that hatch will be drab, rusty colors.
