How Stuff Works: Fly Boxes

I’m a bit of an oddball. This is not exactly breaking news for most folks who know me.  But to paraphrase John Gierach, “If, from time to time, people don’t walk away from you shaking their head… You’re doing something wrong.”  I could certainly dedicate an entire article, or even a book, to my oddball qualities, but for this article, I am referring to one specific oddball quality.  I fish and guide with a set-up that combines a pack and fly boxes all in one contraption. You’ve seen it.  It’s my chest fly box, custom built by the Richardson Chest Fly Box Company in Pennsylvania.  It’s awesome and I love it.

Chest Fly Box

So, that makes it a little more challenging for me to give advice on individual fly boxes.  But I have over the years used about every kind of box and pack known to man.  And along the way I have learned a few things that may be helpful to you when purchasing or organizing your flies.  At the least, it might get you thinking about it.  And who knows?  Maybe one day you’ll come to your senses and buy a Richardson!

While chest fly boxes like mine are more common in the Northeast, they are hardly common.  Most folks go a different route.  They have a variety of different fly boxes that they stuff in a vest, hip pack, chest pack, sling bag, or some other carryall.  No matter how you decide to carry them, fly boxes are essential organizational tools in our sport and it helps to know a few things about them.

Medium Box with Foam

They come in a number of different sizes, from large, briefcase size boxes for boats to ultra slim boxes not much bigger than a smartphone.  When choosing a fly box size, you have to consider how many flies you need to carry, how you’re going to carry them, how big the flies are, and how you want to organize them.  For instance, a big, briefcase size box may hold every fly you have but it won’t be very portable when wading creeks.  Or a small, ultra slim box might be convenient to slip in a pocket, but if you plan to store bass bugs in it, you’ll only be able to carry a couple and you won’t be able to close the lid.

In addition, you’ll have to consider how you want to organize your flies within your box. There are countless options for securing your flies from slot foam, flat foam, and nubby foam to compartments, clips, and magnets.  Some boxes might even have a combination of both, with a type of foam on one side of the box and compartments on the other.  Certainly personal preference plays a big role in you box interior of choice, but there are practical matters to consider as well.

Compartment Box

Compartments tend to lend themselves well to beefier patterns, or large quantities of the same fly. For instance, if you fish a lot of Pheasant Tails and carry a lot of them with you, it’s far easier to dump them all into one compartment rather than trying to line up three dozen Pheasant Tails across multiple rows of foam.  I find foam more useful when I am trying to organize a lot of different patterns but small quantities of each.  It’s easier to see what I have.

Ultra Thin Magnetic Compartments

The type of fly may also determine the best way to store it.  Thin foam or magnetic boxes can be great for midges and nymphs but can crush the hackles on many dry flies.  On the other hand, trying to carry midges in deep compartments can not only be a waste of space, it can be difficult to grasp them with your fingers when removing them from the box.

Finally, when you’re on the stream, you don’t want to spend your time hunting for flies or digging through your pack for fly boxes.  Try to have a designated area of your pack or vest for boxes rather than burying them under a rain jacket somewhere.  And if you carry five fly boxes on the stream, try to make them five different, or at least different looking, fly boxes.  This will save you all kinds of time when trying to locate a specific box of flies.

Flies: Stimulator

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.

Golden Stonefly

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.
