Developed by Randall Kaufmann, this pattern was designed to replicate the large, dark-bodied stonefly nymphs that trout feed on heavily in freestone rivers and mountain streams. Its weighted, anatomically detailed body features a segmented abdomen, prominent wing cases, and rubber legs that push water and create movement on the drift—delivering the lifelike profile that big, bottom-feeding trout key in on.\u003c\/p\u003e\n\u003cp\u003eThe dark coloration makes this pattern especially effective in deeper runs, pocket water, and overcast conditions where it closely matches natural black stonefly species like the giant stonefly (Pteronarcys). It's a big-fish fly built for big water—the kind of pattern you tie on when you want to target the most aggressive, opportunistic trout holding in the heaviest current. A staple on Western rivers and productive anywhere stonefly nymphs are part of the seasonal menu\u003c\/p\u003e","brand":"Jackson Cardinal","offers":[{"title":"Default Title","offer_id":45856852836523,"sku":null,"price":2.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6733\/2779\/files\/kaufman-stone-black_1_COB.webp?v=1775328423","url":"https:\/\/bursonandco.com\/products\/kaufman-stone-black","provider":"Burson \u0026 Co","version":"1.0","type":"link"}
