Grasshoppers and crickets are used widely in ecological, cytogenetic and bio-acoustic research, and have recently become important subjects in evolutionary biological studies. They are also increasingly used in the field of conservation as indicators of undisturbed habitat.
Most of the 170 species of grasshoppers and crickets included in this book can be identified instantly by their songs – and often more reliably than from their appearance. Orthopterans have recently become important subjects in evolutionary biological studies and are also increasingly used in the field of conservation as indicators of undisturbed habitat. The book comprises the following chapters: Introduction; Acoustic Methods; Sound Production and Reception of European Orthoptera; The Nature and Function of the Songs; The Value of the Songs in Taxonomy and Identification; Key to the singing Orthoptera of Western Europe, based primarily on their Songs; and other Animal Sounds that could be confused with Orthoptera Songs – illustrated with over 1600 oscillograms; three Appendixes (Check-list of the species included; Summary of Nomenclatural Changes; Data for the Song Recordings); Glossary; References; Index to Vernacular Names; and General Index.
A work on the songs of the grasshoppers and crickets of Western Europe, with over 1600 oscillograms taken from the 174 species and subspecies covered, as well as 11 confusibles from other orders (cicadas, amphibians and birds).
Essential guide to the specialist literature for the identification of British insects and arachnids.
Orthoptera is one of the most important and interesting Orders of the Class Insecta. They include grasshoppers and crickets that have a fundamental role in many terrestrial ecosystems. In this complete and updated publication all the 382 taxa (species and subspecies) of Orthoptera nowadays known from Italy are treated; 162 of these are endemic! Unfortunately, as well as for other groups of organisms, also orthopterans have many species suffering from maximum degree of threat, according to the Red List of Threatened Species compiled by the International Union for Conservation of Nature (IUCN). Therefore, Grasshoppers & Crickets of Italy is very important also from a conservation point of view; it allows to recognize the endangered species for planning interventions to safeguard them. This new volume is an absolutely innovative tool in the field of nature handbooks. The authors have succeeded in realizing a text with a new and appealing graphic design, easy to consult, full of photos of morphological details useful to identify the species also by non-experts. Furthermore, very useful for the field work are the maps of the distribution areas, detailed at provincial level, for each species. This book will be useful not only for orthopterists, but also for young entomologists who will be able to measure their ability in identifying species, for agricultural technicians and for all nature and entomology lovers. Gli Ortotteri sono uno degli ordini più importanti e interessanti della grande classe degli insetti. Essi comprendono grilli e cavallette, che rivestono un ruolo fondamentale negli ecosistemi terrestri. In questa pubblicazione completa e aggiornata sono trattati tutti i 382 taxa (specie e sottospecie) di Ortotteri conosciuti oggi in Italia; di questi ben 162 risultano endemici, cioè esclusivi del nostro Paese! Purtroppo, come per altri gruppi di organismi, anche tra gli Ortotteri figurano specie al massimo grado di minaccia, secondo la lista rossa stilata dall’IUCN. Grasshoppers & Crickets of Italy è utile, quindi, anche dal punto di vista conservazionistico, per conoscere le specie in pericolo e attuare interventi in grado di garantirne la tutela. Questa nuova guida è uno strumento assolutamente innovativo nel campo dei manuali naturalistici di campagna. Si tratta di un volume con una veste grafica moderna e accattivante, di facile consultazione, ricchissimo di immagini di particolari morfologici utili all’identificazione delle specie anche da parte di non esperti. Utilissime, per il lavoro sul campo, anche le mappe degli areali di distribuzione, dettagliate a livello di singola provincia. Una guida utile, non solo agli ortotterologi, ma anche ai giovani entomologi che vorranno misurarsi con la loro capacità di identificare le specie, ai tecnici agricoli e a tutti gli amanti della natura e dell’entomologia.
The definitive photographic identification guide to the orthopterans of the region, complete with sounds. This is the first guide to the 261 species of orthopterans – the grasshoppers, crickets and katydids – of Britain and western Europe ever published. Set out in a clear and accessible format and featuring a combination of photographs and illustrations, the book covers identification criteria of all of the main species and subspecies, with detailed photographs of males and females, distribution maps, status, habitat descriptions, oscillograms, advice on where and when to find them, and tips to avoid confusion during the often tricky process of identification. Comprehensive general chapters also cover morphology, ecology and habitat, and assist with research in the field. What makes this work the total package? The book comes with a CD, featuring 222 orthopteran songs. Together, book and CD make this the definitive guide to these insects and a rich resource for any naturalist in the region.

The Royal Entomological Society (RES) and Wiley-Blackwell are proud to present this landmark publication, celebrating the wonderful diversity of the insects of the British Isles, and the work of the RES (founded 1833). This book is the only modern systematic account of all 558 families of British insects, covering not just the large and familiar groups that are included in popular books, but even the smallest and least known. It is beautifully illustrated throughout in full colour with photographs by experienced wildlife photographers to show the range of diversity, both morphological and behavioural, among the 24,000 species. All of the 6,000 genera of British insects are listed and indexed, along with all the family names and higher groups. There is a summary of the classification, biology and economic importance of each family together with further references for detailed identification. All species currently subject to legal protection in the United Kingdom are also listed. The Royal Entomological Society is one of the oldest and most prestigious of its kind in the world. It is the leading organisation for professional entomologists and its main aim has always been the promotion of knowledge about insects. The RES began its famous Handbooks for the Identification of British Insects in 1949, and new works in that series continue to be published. The Royal Entomological Society Book of British Insects has been produced to demonstrate the on-going commitment of the RES to educate and encourage each generation to study these fascinating creatures. This is a key reference work for serious students of entomology and amateur entomologists, as well as for professionals who need a comprehensive source of information about the insect groups of the British Isles they may be less familiar with.
Radiations, or Evolution in Action We have just celebrated the “Darwin Year” with the double anniversary of his 200th birthday and 150th year of his masterpiece, “On the Origin of Species by means of Natural Selection”. In this work, Darwin established the factual evidence of biological evolution, that species change over time, and that new organisms arise by the splitting of ancestral forms into two or more descendant species. However, above all, Darwin provided the mechanisms by arguing convincingly that it is by natural selection – as well as by sexual selection (as he later added) – that organisms adapt to their environment. The many discoveries since then have essentially con?rmed and strengthened Darwin’s central theses, with latest evidence, for example, from molecular genetics, revealing the evolutionary relationships of all life forms through one shared history of descent from a common ancestor. We have also come a long way to progressively understand more on how new species actually originate, i. e. on speciation which remained Darwin’s “mystery of m- teries”, as noted in one of his earliest transmutation notebooks. Since speciation is the underlying mechanism for radiations, it is the ultimate causation for the biological diversity of life that surrounds us.
The present book is not a classical manual on Zoology and the reader should not expect to find the usual treatment of animal groups. As a consequence, some people may feel disappointed when consulting the index, mainly if searching for something that is considered standard. But the reader, if interested in Zoology, should not be disappointed when trying to find novelties on different topics that will help to improve the knowledge on animals. This book is a compendium of contributions to some of the many different topics related to the knowledge of animals. Individual chapters represent recent contributions to Zoology illustrating the diversity of research conducted in this discipline and providing new data to be considered in future overall publications.
