The Mayfly Guide

Mayfly identification made clear and simple

For anglers looking to increase their catch, this indispensable guide reveals the steps to easily and confidently identifying the three stages—nymph, dun, and spinner—of many common mayfly species found in North America. Including information on when and where mayflies hatch and how trout feed on them along with illustrated species charts, this reference avoids the abstractions of complex scientific keys and words and instead favors a practical and visual approach that supports quick learning. Waterproof pages and a small trim size enhance the guide’s portability, making it as sensible as it is useful.
