This definitive guide to the County's butterflies, past and present is based on the results of the Suffolk Butterfly Survey 1983-1985 and includes maps of all the species still to be found in the County. Quality colour photographs of each species, taken by local naturalists who helped in the survey, enable the book to be used as an identification guide. The authors, two well known naturalists and conservationists, have drawn on a wealth of historical information to show the changes that have happened to Suffolk's butterfly populations.
