Emergers & Cripples Quick Picks Best All-Around: RS2 Emerger Fly - A go-to when trout are keyed on tiny mayflies and sipping just under the film. The sparse profile is subtle enough for technical tailwaters, but versatile across a wide range of sizes and colors. Best Value: WD-40 Fly - A confidence pattern for anglers who want one slim fly that covers Baetis and small midge-type meals. It’s easy to fish on a nymph rig or in the film when fish refuse a standard dry. Best for Caddis Emergence: Emergent Sparkle Pupa Fly - Built for those “something’s happening but they won’t eat the adult” moments during a caddis hatch. It rides naturally in or just under the surface film, right where trout often focus during the emergence. Best for Technical Water: Juju Emerger Fly - A small, clean profile that fits pressured rivers, spring creeks, and clear tailouts. The CDC-style look helps it fish like a true emerger when trout are tracking naturals in the top few inches. Best for Film Feeders: Mayfly Cripples Fly - A smart pick when fish are eating “stuck” bugs and you’re seeing refusals to high-riding dries. The cripple profile suggests an insect that’s struggling to finish the hatch, which trout can key on hard. How to Choose Emergers & Cripples What these flies imitate (and why trout care) Core idea: Emergers and cripple patterns imitate insects trapped in the surface film or failing to fully hatch. That’s a high-percentage feeding lane, because the naturals can’t escape and trout can eat them with less effort than chasing duns. Use them when: You see steady, subtle rises (bulges/sips), but your dry fly gets refusals or goes ignored. They’re also a strong choice when you see shucks on the water or on streamside rocks. Match the “lane” first: film, just under, or deeper In the film: Choose classic emergers and cripples when fish are feeding in the top inch or two. These are ideal on calm tailouts and flat runs where trout have time to inspect a fly. Just under the film:
