Butterflies of Hertfordshire and Middlesex

"Substantial volumes of data are now available through the efforts of volunteer recorders (4,800 people contributed records to this volume); as a result the standard of regional butterfly books has improved considerably in recent years. This is one of the 'new breed' of books: professionalIy produced, and as much a historical record of times gone by as presentation of current butterfly distribution. It is a substantial book, and one might question how 266 pages of A4 sized pages can be filled with a mere 35 species. The author has given much thought to what information can and should be usefully included – and succeeded admirably [...] The species accounts (pp. 32-166) are well-written and informative, supported by excellent photographs of adult butterflies, and include current and historical mapped distribution [...] In common with other recent regional books, this is written for butterfly watchers, and it became evident that this is a book about adult butterflies and where to find them. It is disappointing – and frankly surprising – that with so few species to chronicle, all of whose life histories have been well-documented, there are so few photographs of early stages. [...] J. A lack of early stages aside, this is a successful book, reasonably priced."
