This attractor dry fly is great for imitating stoneflies and caddis.


The Stimulator dry fly is a go-to attractor dry fly, particularly when you're dry fly fishing during a big stone fly hatch or salmon fly hatch. This dry fly sits up high in the water, even in faster water. Its "bugginess" also makes the Stimulator one of the very best dry flies to use as an attractor dry fly pattern "prospecting" for trout when there is no hatch.
Sizes: 8, 10, 12, 14, 16.

    Did the trick! - 10/6/2015

    I was fishing on the Indian River in the Adirondacks, but not having much luck most of the day. As it was starting to get dark, I had this fly on (orange color) and was casting from the shore and letting it drift down river. A nice Brown Trout absolutely nailed this fly. I'm planning to pick up some other colors of this fly.

    Should be a lot of fun once the weather warms up! This fly seems like it will last. Quality materials and great color patterns.

    Stimulator! - 2/12/2015

    In many fly boxes, including mine, this hardy fly has replaced the elk hair caddis. It's a great fly that really lives up to its name.

    Great Dry Dropper - 7/27/2014
    By: from River Falls, WI

    Love this as a dry dropper when there's no hatch. Very well made and love the way it sits on the water. Lost it on large brown last night and will be ordering more.

    Great Fly - 5/22/2013

    Great fly pattern. I guess Orvis doesn't get the credit for inventing the pattern but it is a well tied fly on a strong hook. A must for every fly box.

    This is a Go-to Fly! - 2/22/2013

    This is my go-to prospecting fly for just about any stream/creek/small river. It mimics so many species of insects that trout prey upon it is pretty much universal. Not only can you fish it dry, I have often caught fish while stripping the fly in for another cast. I've compared this fly to other stimulators tied by other online fly stores, and there is no doubt about it. These flies stimulate a strike where others do not. Try it for yourself. These flies last longer and yield more strikes. There's really no substitute.

    My Dry Dropper Choice - 2/21/2013
    By: from Avon CT

    Although listed under stoneflies, a yelllow or orange Stimulator in size 12 or 14 is my go-to choice for my dry-dropper rigs. In smaller sizes it can imitate a caddis or small hopper. But it really shines as an indicator with a dropper and every so often the Stimulator gets nailed too- especially in broken faster water. Don't fish the dry / dropper on too fine a tippet though or you will just twist yourself into frustration.
