Around a year and a half ago an idea came to me, what if there was a clear, simple, and extremely effective pocket guide that taught the basic bugs that fish eat, and some of the basic fly patterns that mimic them. It would need to be direct and still cover the most important principles on choosing which fly to fish in varying situation. It would have to be pocket size, of course, and inexpensive so everyone could benefit from it.
From there my ideas snowballed, and with much help from an awesome designer these are the final products:
They each contain details about the four major aquatic insects that fish primarily feed on; mayflies, stoneflies, caddis, and midges. Adult Aquatic Insects is a guide for dry fly fishing, while Aquatic Insects focuses on nymphs, larva, and pupa.
