7Phil has spent countless hours at lakes studying the food sources that make up the diet of trout; then set up home aquariums to more closely observe the movement, development, and emergence of the aquatic insects. In this book he explains the link between understanding the food base within lakes to designing effective fly patterns for these environs. Phil covers all major trout food sources for the whole year. He gives detailed information on each, plus how to tie a representative pattern and fish it effectively. Numerous proven stillwater patterns are given for each insect and include clear and concise tying instructions. This book will be a long-standing still water fly pattern reference for years to come.
