Mayfly Nymph Fishing Fly Patterns imitate the Nymph stage of the Mayfly’s life cycle. Mayfly Nymphs are the underwater stage of the May Fly. They are found pretty much all over the world and are a favorite food of fish. Some say Mayflies make up 60% of a fishes diet.
Mayfly Nymphs will be found in fast moving water, in shady spots.
They will be found clinging to rocks and sand, burrowed into the stream bed, swimming, or crawling along the bottom.
Mayfly Nymphs are very sensitive to pollution and will not be found in polluted waters.
There is a group of fly fishermen that feel that fishing Nymphs is below them.
There is also a group of fishermen that only fish Nymphs and say that it is the best way to catch fish. Try it out, there are no real rules to fly fishing. Try what works. All of the Nymph pattern fishing flies are not being tied for decoration. They really do catch fish.
