Trout Fly Library

A reference library of trout fly patterns — dry flies, nymphs, emergers, streamers, and wet flies — with the insects each one imitates.

• Adams (dry) — The most versatile dry fly ever tied. Imitates a broad range of mayfly duns and works year-round on virtually any trout stream. Matches: Mayfly, Blue-winged Olive, Pale Morning Dun.
• Comparadun (emerger) — Sits low in the film like a crippled emerger. Devastating during heavy hatches when fish are keyed in on vulnerable emerging duns. Matches: PMD, Blue-winged Olive, Callibaetis.
• Copper John (nymph) — A weighted, flashy nymph that sinks quickly and attracts fish from a distance. Works as both a stonefly and mayfly imitation. Matches: Mayfly, Stonefly nymph.
• Elk Hair Caddis (dry) — The definitive caddis dry fly. High-floating elk hair wing makes it visible in fast riffles. Dead drift or skate across the surface during egg-laying. Matches: Caddisfly, Little Black Caddis, Spotted Sedge.
• Hare's Ear Nymph (nymph) — The fuzzy hare's ear dubbing perfectly imitates the gills and legs of emerging mayfly nymphs. A staple of every nymph fisher's box. Matches: Mayfly, Caddis larva, Crane Fly.
• Hopper Juan (dry) — A foam hopper pattern that floats like a cork. Cast tight to undercut banks and let it sit. Late summer's most exciting way to catch large trout. Matches: Grasshopper, Cricket.
• March Brown (dry) — One of the first significant hatches of the season. Large enough to excite even the biggest browns. Fish in the morning during cool spring days. Matches: March Brown Mayfly, Stenonema.
• Midge Cluster (dry) — Imitates a cluster of adult midges on the surface. Critical for winter and tailwater fishing where midges are the primary food source year-round. Matches: Midge adult, Griffiths Gnat.
• Muddler Minnow (streamer) — The original sculpin imitation. Works on the surface or subsurface. Dead drift it through deep runs for large browns, especially in fall. Matches: Sculpin, Baitfish, Large Grasshopper.
• Pale Morning Dun (dry) — Critical summer hatch fly. Fish during the late morning hatch on tailwaters and freestone streams from June through August. Matches: Pale Morning Dun, PMD, Ephemerella.
• Parachute Blue-winged Olive (dry) — Essential for spring and fall BWO hatches. The parachute post makes it highly visible to the angler while presenting a realistic profile to the fish. Matches: Blue-winged Olive, Baetis.
• Pheasant Tail Nymph (nymph) — The most effective nymph pattern worldwide. Imitates a broad range of mayfly nymphs. Fish under an indicator or as a dropper. Matches: Mayfly, Blue-winged Olive, PMD, Baetis.
• San Juan Worm (nymph) — Deadly after rain or high water when worms get washed into the stream. A polarizing fly but undeniably effective on pressured tailwaters. Matches: Aquatic worm, Crane fly larva.
• Soft Hackle (emerger) — Fished on the swing or dead drift in the film. The soft hackle pulses with life on every twitch. One of the deadliest hatch patterns ever created. Matches: Caddis, Mayfly emerger.
• Stimulator (dry) — The go-to stonefly and large caddis imitation. Works as an attractor pattern even when nothing specific is hatching. Great in fast, broken water. Matches: Salmon Fly, Golden Stonefly, Large Caddis.
• Trico Spinner (dry) — Imitates spent Trico spinners during late summer spinner falls. Often the most important fly for selective fish on flat tailwater sections. Matches: Trico, Tricorythodes.
• Woolly Bugger (streamer) — The most versatile streamer in the box. Imitates leeches, baitfish, and large nymphs. Strip it in the current, dead drift it, or jig it along the bottom. Matches: Leech, Baitfish, Crayfish, Large Stonefly nymph.
• Zebra Midge (nymph) — Essential winter and tailwater midge larva pattern. The silver bead and black wire ribbing create a deadly segmented appearance. Fish deep and slow. Matches: Midge, Chironomid.
