Peter Lapsley, who died in August 2013, was an inveterate fisher of trout, sea trout and grayling in the UK and overseas for over 50 years and was a qualified game angling instructor. He contributed countless articles to a wide range of British and overseas game angling and field sports magazines. The Pocket Guide to Matching the Hatch was the eleventh book he had written (or in this case co-written). Peter fished chiefly on the chalkstreams and stillwaters of southern and south west England but always had a soft spot for the wild trout waters of Scotland, Wales and Ireland. Dr Cyril Bennett has been a flyfisherman for nearly 50 years during which time he has been fascinated by the fly life of rivers. He was a founder member of the Riverfly Partnership and pioneered the Anglers Monitoring Initiative to enable anglers to detect pollution incidents. His PhD with the University of London was on the ecology of mayflies and he is a Fellow of the Royal Entomological Society. He lives in Amesbury, in the heart of the southern chalkstreams, and he is married with two children and two grandchildren.
