    Great pattern & stays together

      I've been amazed at the number of time I've gone back to this fly and caught fish when other patterns aren't producing. This pattern is a great general pattern when you've had multiple hatches and especially some larger caddis hatches. The nice thing too they are tied well enough that they hold up after catching fish.


      • Familiarity: I've put it through the wringer

      Umpqua makes some fantastic flies. I have been fishing Umpqua flies for over 20 years, and they are the best quality flies I have purchased. the quality is unmatched as is the selection.
      Buy Umpqua and slay the trout.

      Always gets a rise out of 'em.

      • Familiarity: I've put it through the wringer

      Brookies are eager fish, but that doesn't mean the stimulator doesn't work. It's also a productive pattern for spring creek bows during terrestrial season imitating buggy big meals or a big caddis. It's my go to for brookies in spring and summer.

      A summer staple

      • Familiarity: I've put it through the wringer

      Once the temperatures hit the 80s and the hoppers start flopping around, I dont leave home without this fly. In different sizes and colors it can imitate pretty much anything from a caddis to various species of stoneflies, but I find this fly really gets fish up when the hoppers are out. Fish this fly against the banks near undercuts/cover and you'll have a hell of a day. Trout tend to hit terrestrials hard, so hold on!

      Great fly!

      • Familiarity: I've used it once or twice and have initial impressions

      I caught rainbow after rainbow on one of these when the fish were feeding on the surface. The only issue was it had to be dried out several times to keep it floating (I forgot my floatant!)

      Great fly!

      Great attractor pattern

      • Familiarity: I've put it through the wringer

      Every fly box needs this pattern in all sizes. My favorite is a yellow size 8. I know, I know, a lot of fly guys and girls will say this is too large. But I think larger makes a better attractor unless you are fishing a hammered stream. Larger floats longer using a dropper. Larger is better for Giant Yellow Stones that are, well, giant. I've seen aggressive spawning male bows attack larger Stimulators in the dead of winter, on the surface. I have seen large yellow Stimulators work exceedingly well as a hopper pattern, although the smaller sizes will work also. In fact, in my opinon, a yellow Stimulator can be a better hopper pattern than a hopper pattern. One of my best memories is the giant sucking sound a big fish makes when it sluuuuurps in a large Stimulator on still waters. Orange Stimulators work very well during the October Caddis hatch as these orange Caddis, are, well, orange. I use #10s for the Octobers because where I live that is the size they are. I have even seen a huge sucker hook up on a #10 Orange Stimulator during the October Caddis hatch, on the surface! I wholly agree with Mr. Collett's review below. Although I like to fish the larger Stimulators, I routinely use # 16 on rivers and creeks as a very effective caddis pattern. In fact, one of the biggest fish I ever lost hooked up on #16 yellow Stimulator. Buy 'em. They are good.

      very versatile

        Get this fly in a few different sizes and colors and you're good to go! Use it as a caddis, hopper, golden stone, yellow sally, salmon fly, etc. This fly floats well too so its great for faster water or holding up a dropper.
