JHFLYCO Mayfly Life Stages Assortment

Mastering the Mayfly Hatch Trout eat far more mayfly nymphs and emergers than they ever do duns — but most anglers fish only the surface. This loaded fly box covers the full mayfly lifecycle so you can fish what trout actually eat. This hand-picked assortment combines weighted nymphs, soft-hackle emergers and cripples, and high-floating adult duns to cover the full mayfly year — from technical Blue-Winged Olive hatches in spring and fall, through summer Callibaetis, to the big Green and Brown Drake windows of early summer. Inside, you'll find life stage staples — the Beadhead Pheasant Tail, Beadhead Callibaetis, and Henderson's Master Baetis — plus surface workhorses the Blue-Winged Olive, Gray Para Drake, and BJ's Dancing Fairy, all balanced across sizes 8–14 to match the hatch and the season. Each fly is mounted in our JHFLYCO Foam Fly Box in Orange — a high-visibility foam-slit box built to hold your patterns securely and keep them organized through long days on the water. The orange color makes it easy to spot in your pack or on a tailgate, and the slim profile fits cleanly in chest packs and sling bags. Included Patterns 3 of each pattern – 24 flies total Beadhead Callibaetis (#12): A weighted nymph that imitates the Callibaetis mayfly — a staple food source in lakes and slow water. The bead gets it down to cruising fish in the film and just below. Beadhead Flashback Pheasant Tail (#12): The classic Pheasant Tail with a reflective flashback wingcase — the do-everything mayfly nymph that covers Baetis, PMDs, and more. If you fish one mayfly nymph, fish this. Beadhead Soft Hackle Flash Pheasant Tail (#14): A Pheasant Tail with added movement and attraction — the soft hackle pulses like an emerging mayfly and fishes beautifully on the swing or under an indicator. Henderson's Master Baetis – Gray (#14): A deadly mayfly emerger that imitates the vulnerable transition stage just under the surface film — the moment trout key on hardest during a Baetis hatch. Green Cripple Drake (#12): A Green Drake trapped half-out of its nymphal shuck in the surface film — the easy, can't-get-away meal that picky fish single out during the drake hatch. Gray Para Drake (#12): A high-floating parachute dun that matches large mayflies like the Green Drake, Gray Drake, and Slate Drake — visible, durable, and built for the big-bug windows of summer. Blue-Winged Olive (#12): The classic hackled dun for the hatch that defines technical dry fly fishing — an olive body and slate-gray wing that produces from the first spring BWOs through the fall. BJ's Dancing Fairy (#8): A parachute-style Brown Drake imitation built for the twilight windows when these big mayflies bring every trout in the river to the surface.

Mayflies are the heart of trout fishing — the hatches anglers plan entire trips around. But trout eat far more mayfly nymphs and emergers than they ever do duns, which is why the anglers who consistently catch fish are the ones fishing the whole lifecycle, not just the visible bug on the surface. This curated assortment is built to help you cover mayflies through every productive moment — nymphing the bead-heads pre-hatch, swinging the soft hackle as the emergence starts, drifting a cripple in the film, and finishing with a high-floating dun when fish commit to the surface. From spring creeks to freestone rivers, this all-in-one mayfly system helps you stay confident, fish efficiently, and make every drift count. Fishing Dry Flies Only? If you primarily fish the surface and don't need the subsurface coverage, check out the JHFLYCO Loaded Fly Box – Mayfly Dun Assortment — a dry-fly-only box focused on adult mayfly patterns for the hatch itself.
