Pattern Database

The F-Fly was developed in Europe as a highly impressionistic mayfly and midge imitation, designed specifically for pressured trout and technical water. Rather than imitating exact details, the pattern relies on profile, posture, and movement—key triggers that trout respond to when insects are trapped in the surface film. Using only CDC for the wing, the F-Fly excels at riding low, mimicking spent or emerging insects that trout feed on confidently. Its simplicity allows it to match a wide range of small mayflies and midges, making it a favorite on spring creeks, tailwaters, and slow glides. The F-Fly's minimalist design and effectiveness have earned it a permanent place among modern dry-fly staples. This ultra-simple recipe creates a low-riding silhouette with exceptional natural movement—perfect for selective trout feeding in calm, clear water.

George Griffith's cluster midge pattern has been fooling trout for decades. The palmered grizzly hackle through peacock herl perfectly imitates a clump of midges on the surface.

René Harrop's WD-40 is a masterclass in minimal fly design — wood duck legs, dubbing body, and snowshoe rabbit wing suggest a midge pupa or BWO emerger just below the film. One of the most effective tailwater nymphs ever created.

Ted Welling's Zebra Midge is the go-to tailwater midge larva pattern. Two materials — thread and wire — tied on a beaded hook. Deceptively simple and devastatingly effective.
