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.

    Great Dry Dropper - 7/27/2014

    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 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.

    Well tied. Durable. Good for prospecting when you don't know what else to use.

    High quality flies, I am impressed. Stand up to all of the abuse a newbie like me can give them.

    Have yet to fish this fly. Appears to be well tied, a quality Orvis product. Expect very satisfactory results based on history of the pattern.

    When nothing else seems to be bringing them to the surface, try tying on one of these. Excellent attractor fly.
