Note that only the stonefly nymph above is a specific imitation of an actual insect. The others are merely generic representations. You will achieve the best results by using specific patterns, such as Perfect Fly brand flies, which are the most realistic and lifelike flies around.
See our Mayfly Nymph Fly Tying DVD for instructions on tying the best mayfly patterns, as well as our other DVD's, covering a host of fly fishing topics.
