Here is all you need to know about these 15 flies and why they are the very best options for trout fishing in September.


First up, we have three hoppers to choose between. These flies are known as essential flies for late summer evenings, which is why they continue to be useful throughout September.

Fat Albert - Fly Fishing Flies for September

Fat Albert - Purple

Long regarded as one of the best hoppers around, Fat Albert Purple flies are still a must-consider if you are looking for new flies for trout this September. The purple color helps make these flies all the more visible and attractive to the trout, and it's meant to imitate full-bodied bugs very effectively, so it's excellent all-round. They are also relatively easy to tie up, so they are suitable for beginners and more advanced anglers.

Chubby Chernobyl Fly Fishing Flies for September

Chubby Chernobyl

This popular attractor pattern is one of the favorite options throughout summer, into late summer in September, and it should be considered as highly as the purple Fat Albert. It is designed to imitate golden flies and other hoppers, and it comes in a variety of sizes and colors to use in various settings. It is also incredibly robust, wind-resistant, and quite a bit heavier than many others, keeping it on the line much more readily.

 Daves Hopper in Yellow - Best Hopper for Fly Fishing

Dave’s Hopper

If you are after a fly that will fool pretty much any trout at any time, then Dave's Hopper is an absolute must-have in your box. Many people swear by Dave's Hopper, and with good reason, so it's something that you are going to want to consider for this time of the year. It is made from very tightly bound deer hair, which means that it is also one of the most buoyant flies you can buy. It also tends to have a perfect searching pattern, making it just an excellent all-around option for September, even too late in the month.

Best Dry Fly and Nymph Fishing Flies for Fly Fishing


For a fly that has a huge amount of wind resistance, it is always a good idea to look into getting a large dry fly. On the downside, these are not the top choice if you have trouble with leader twists. But all around, the following three large dry flies are well worth a shout.

Adams Fly - Best Dry Fly for September Fly Fishing


This option has been in existence for almost 90 years, and it is regarded as a classic fly for trout fishing - one that you at least need to try out once in your life, if not more often. Because of its grey body and brown hackles simultaneously resemble a few different American and large European flies. It is versatile, suitable all year round, more or less, and beneficial for the beginner. It's a must this late summer and early Autumn, as at many other times of the year.

Parachute Mahogany Dun

Parachute Mahogany Dun

When you want to reach out to some rising trout this September, you will want to have some parachute mahogany duns in your arsenal. It is incredible how realistic these look, and they also tend to be one of the more visible options for the angler himself, which makes life a lot easier as the sun starts to fade on those long September evenings. If you stock up on these now, they will take you through to the end of September and perhaps even into October, if you are lucky.

Royal Wolf - Best Dry Fly of All Time

Royal Wolf

As September moves on and you start trying to get more and more trout in, you will find that you are working with decreasing light levels. Because of this, it, therefore, becomes imperative that you have flies that are going to be easy to see in low light. The Royal Wolf fits in with that goal, with its bright red silk body and peacock-like colors. This gets the trout interested, as well, so it's a great choice in overfished areas where the trout have gotten wise to the fishermen.

Large Brown Trout caught Fly Fishing


If you want the benefits of the bigger dry flies, but you also want to have a little extra control, then the small dry flies could be for you. In truth, they will serve a different purpose, so you should make sure that you have some available as you get into and through this next month.

Hot Wing Caddis

Hot Wing Caddis

This is an ever-popular option that you are going to want to consider. Traditionally made from elk hair, the caddis now often also comes with an extra bit of high-vis yarn to make it that little easier to see. For this reason and many others, it is a very useful one to have for those shortening September evenings. It is often extremely well tied, too, so you don't have to worry about losing it, even if you are at it for hours and hours.

Parachute Adams

Parachute Adams

As you have seen already, the theme when it comes to September flies is very much for easy visibility and trackability. For that reason, another fly to consider is the well-loved and adored Parachute Adams, which is easy to track in a wide range of conditions and is ideal for fishing in low light in the evenings, and it's perfect for when things get cooler, too.

Comparadun PMD

Camparadum PMD

This perfectly combines a very lifelike and believable silhouette, high visibility, and some fantastic buoyancy. Many anglers like to go straight for the Camparadum at any time of year, and it is just as good in September as any other time, and it's one to consider, anyway.



Emerger flies differ from other types in that they are designed to look as though they are genuinely hatching out of the water. They come in a wide range of guises, including the following three favorites.

CDC Midge Pupa - Red

CDC Midge Pupa - Red

This has proven itself to be a very useful option under a range of different conditions, and it is often relied upon when no other option seems to be working all that well. You should make sure that you have some CDC Midge Pupa in your arsenal, especially the vibrant and visible red variety, at this time of year in particular.

Crystal Midge

Crystal Midge

The Crystal Midge, as the Midge Pupa above, is a reliable fly and one that you are going to find very useful to have on you, even if you only use it occasionally when nothing else is working. It's terrific if you are fly fishing on water that gets a lot of pressure, whether in a river or still waters.

 CDC Caddis Emerger

CDC Caddis Emerger

Our last emerger on the list is this all-around wonder: an excellent pattern for tough trout who won't be easily fooled.  Emerging Caddis can be detected by trout hitting the surface with extra effort as the emergent stage for caddis happens very fast.

Mayfly Nymph


Finally, we have the nymphs. These three will round off your fly box nicely for the month.

Sparkle Worm

Sparkle Worm

The Sparkle Worm is versatile in that it can be wrapped around to make larger bodies and yet has a narrow integral core. It won't disintegrate in salt water, and it lasts a long time, so it's an investment to have one in your fly box.

Glow Bug Red Dot

Glo Bug Red Dot - Orange

Arguably one of the strangest looking of all the flies, it is still one of the best and proves extremely attractive to all kinds of trout in many different settings. So wherever you are planning to fish, have one of these handy with you at all times.

Formally Known as Prince - Fly Fishing Flies

Formally Known As Prince

The Fly Formerly Known As Prince has a truly distinctive look and an exceptionally modern pattern. The original Prince Nymph will seem outdated and ordinary once you have started using this one. All in all, you'll be glad to have tried this one out.
