What type of fly fisher are you? Maybe your motto is “Dry Fly or Die” and the Parachute Adams is a go-to during a hatch. Perhaps Kelly Galloup is your idol, and there’s always a streamer fly on the end of your line. Love fly fishing emergers? There’s no question it’s a favorite of mine, as it’s my most popular presentation for Trout Unlimited clubs and fishing groups. For those trout fly fishers that love to catch fish on a consistent basis, though, look no further than nymphing.

Anglers agree that trout eat most of their diet subsurface, concentrating on nymphs, bait fish, and other food sources that get delivered to them by moving water. Successful fly fishers maximize their catch rate by focusing on these food sources, especially when there is no hatch present. Nymphs are especially important, as they form a significant portion of their diet. Fly fishers have been imitating them for decades with patterns like the Hare’s Ear and Pheasant Tail. So where do Euro nymphs fit in, what exactly are they, and why are they so darn effective?
