Fish Food: A Fly Fisher's Guide to Bugs and BaitBy Ralph CutterA thorough examination of the foods trout eat, by a master of 
observation and adaptation whose curiosity has led to innovations in fly
 design and angling techniques. Covers specific trout foods such as 
blue-winged olives, caddis, damselfies, scuds, and ants, and general 
information, including insect life cycles and taxonomy. Rather than 
accepting point-blank the traditional views of insect hatches, the 
author has donned his snorkeling gear and studied species underwater, 
adapting his fishing to reflect his findings.
