The Meriam-Webster dictionary defines nymph fly fishing as “any of various immature insects; especially: a larva of an insect (as a grasshopper, true bug, or mayfly) with incomplete metamorphosis that differs from the imago especially in size and in its incompletely developed wings and genitalia.” In layman’s terms this means that the insects are still in their underwater stage and have not reached adulthood.

Learning a little about the life cycle of insects will give you a wealth of knowledge for nymph fly fishing. With a little research to determine what type of nymph fly to use for the fish you want to catch, you will enjoy some of the best fishing ever.
