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.

Ginger Caddis

The Ginger Caddis of the Smokies is known in other circles as the Great Brown Autumn Sedge. Many lump it together with a few other similar species and refer to them all just as October Caddis. No matter what we decide to call it, fish just call it food! Caddis of numerous varieties are available most of the year in the Smokies but really seem to come into their own in fall. And of the many caddis species hatching in the fall, the Ginger Caddis is the undisputed king.

Orange Stimulator

Ginger Caddis are big, big bugs – in the hook size #10-8 range to be exact. They are in the stream all year, most of the time in a larval encasement of lengthwise sticks. They feed mostly on decaying leaves throughout the winter and spring, and in early summer, when that food source has diminished, they seal off their cases and remain inactive until late summer. They begin pupation in late summer, with emergence, mating, and egg laying occurring in early fall. Eggs will hatch in late fall when most of the leaves have fallen, and the larvae will again begin feeding on this foliage. Their entire life cycle is completely synchronized with this food source and they are one of the most important converters of leaf material in the woodland streams of the Eastern United States.

What does that have to do with you? Well, it gives you a good idea of what to tie on the end of your tippet. You will probably only see a handful of these on the stream as the adults tend to fly mostly at night, but there is plenty of spillover near dusk and dawn. And trout don’t seem to care that their not supposed to be seeing them in the middle of the day because they regularly take imitations with plenty of vigor!

Neversink Caddis

While there are a number of more exact imitations out there, I have found few flies that work better than an orange Stimulator or an orange Neversink Caddis in sizes #12-8. Even when they’re not hitting the dries, these are both highly buoyant dry flies that do a great job of suspending a dropper. For dropper nymphs, the usual suspects like Pheasant Tails, Princes, and Green Weenies are always good choices. Or you may try a #12 orange soft hackle pattern to imitate the Ginger Caddis pupa.

Actively fishing an orange soft hackle by itself or in tandem with another nymph can be very productive, especially in the early morning. Refer to the Active Nymphing article in the Journal section of my web site for tips. Ginger Caddis begin showing up (hatching) in the Smokies in late September and typically hang around until late October.
