Lady luck smiles upon anglers who use the right flies, fish them in the right places at the right times, and make them behave like the natural insects they are meant to represent. But with such a vast range of fly patterns and sizes available, how do you choose? This completely revised and updated pocket edition provides the answer. Remarkable macro-photography of the aquatic creatures on which trout feed (now enlarged photographs in this pocket edition), an author with 65 years of flyfishing experience, a selection of the world's best fly patterns - these are the ingredients of this invaluable source of practical information. Many of the top experts on flyfishing and flytying agreed to tie flies for Matching the Hatch; in most instances the flies illustrated are their own designs which have now become standard patterns used throughout the world - Jon Beer, Brian Clarke, Alice Conba, Donald Downs, Peter Gathercole, Malcolm Greenhalgh, Melvin Grey, Derek Hoskin, Nigel Jackson, Charles Jardine, Steffan Jones, Peter Masters, Guy Mawle, Peter O'Reilly, Steve Parton, Neil Patterson, John Riegen, Andrew Ryan, Bernard Venables, Conrad Voss Bark, John Wilshaw and Davy Wotton. Trout and the creatures they feed on have not changed, although entomological science has renamed some species. In this revised and updated pocket edition the author has adopted nomenclature used by the Natural History Museum and by colleagues in the Riverfly Partnership.
