This atlas contains 10 kilometre square distribution maps of each of the native and naturalized Orthoptera (bush-crickets, crickets, grasshoppers and groundhoppers), Dictyoptera (cockroaches) and Dermaptera (earwigs), with introductions to each order and also a summary of the occurrence of naturalized Phasmida (stick-insects). The species accounts summarize the status, ecology and the protection/threat status of each species and cross-reference to the main identification guide to these groups in Britain and Ireland.
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.
Provides not only a full description of all the resident grasshopper and allied insect species in the orders Orthoptera, Dictyoptera, Phasmida, and Dermaptera, but also a detailed account both of their past and present status and distribution throughout the British Isles.
