Kaufmann Stonefly Nymph
The Kaufmann Stonefly Nymph is one of the most trusted and effective stonefly imitations ever created. Designed by legendary tier Randall Kaufmann, this pattern perfectly captures the bulky profile, lifelike movement, and natural drift of real stonefly nymphs that live along the bottoms of clean, fast-moving rivers.
Stonefly nymphs are a major food source for both trout and steelhead. Juvenile steelhead feed heavily on them while growing in the river, and that imprint often carries into adulthood, making stonefly patterns a smart choice when targeting returning fish. If a river holds a healthy population of stoneflies, you can bet predators are used to seeing—and eating—them.
Because stonefly nymphs are poor swimmers, they float and drift naturally along the riverbed, which makes this pattern ideal for slow, natural presentations.

FAQ
What makes the Kaufmann Stonefly Nymph effective in the water?
The pattern mimics the bulky shape, natural drift, and slow movement of real stonefly nymphs, which are commonly found in clean, fast-moving rivers. This makes it highly attractive to trout and steelhead that rely on stonefly nymphs as a primary food source.
Is this nymph suitable for use in both still and flowing water?
Yes, it is best suited for fast-moving rivers where stonefly nymphs naturally drift along the bottom. Its design allows for a realistic presentation that works well in current.
Can this pattern be used for steelhead fishing?
Yes, juvenile steelhead feed heavily on stonefly nymphs, and the pattern’s natural appearance and movement make it effective when targeting returning steelhead.


Nathan Lee –
Used this nymph on a clear mountain stream and caught a large brown trout on the first cast. The drift was natural and the fish took it immediately. A solid choice for stonefly season.
Jake Newman –
Fished this pattern during a steelhead run and had several bites. The way it moves in the current is very realistic. Highly recommended for rivers with known stonefly populations.
Jonathan Turner –
Good imitation, especially in fast water. The weight is just right and it stays on the bottom without sinking too quickly. A bit more visible in low light, but still effective.

This is one of the best stonefly nymphs I’ve used. The design matches real nymphs perfectly. I’ve used it in multiple rivers and it consistently produces results.
