Mayflies
Mayflies
Match the hatch across every major aquatic lifecycle with premium mayflies from Casters Fly Shop. Found in massive abundance throughout global freestone rivers, tailwaters, and stillwaters, mayfly patterns represent an essential, year-round staple in any technical trout box. Our curated selection of mayfly patterns includes highly durable, precisely drifted flies engineered to represent everything from bottom-dwelling nymphs to vulnerable emergers, upright duns, and spent spinners.
Adult dry flies, emergers, and weighted mayfly nymphs:
• High-floating adult duns and spinners: Built to ride high and visible in fast pocket water and smooth flat glides. Tied with premium hackles, deer hair, and buoyant synthetic wings, these topwater patterns perfectly mimic upright wings and spent profiles to fool selective, surface-feeding trout.
• Realistic emerging mayfly pupae: Intercept feeding fish focused on the surface film. Featuring translucent dubbing bodies, trailing shucks, and low-profile wings, these patterns capture the exact moment a mayfly is highly vulnerable to trout during a heavy hatch.
• Weighted mayfly nymphs and subsurface imitations: Drop deep into fast current columns and heavy velocity pockets. Tied on premium high-carbon hooks and outrigged with dense brass or tungsten beads, these subsurface patterns represent classic pheasant tails and burrowing nymphs rolling along the riverbed.
Durable, high-yield patterns for technical rivers:
Every single mayfly pattern in this collection is handcrafted using world-class materials—including premium hooks, non-absorbent synthetic dubbings, and natural feathers—to ensure absolute structural durability under heavy current torque. These high-turnover selections are balanced to cast cleanly, maintain correct tracking profiles, and hold secure hooksets fish after fish. Pair these essential mayfly selections with our technical weight-forward floating fly lines, tapered fluorocarbon leaders, and premium sighter material to fish your local waters with total confidence.
