Ragge, D.R., 1965
Grasshoppers, Crickets & Cockroaches of the British Isles
The standard dichotomous keys to families, genera, species are followed by detailed species accounts, often with named colour forms. All the native species are illustrated, often with several colour forms.
Song diagrams representing the beats, their relative loudness and timing provide an alternative method of identification in the field.
The book also gives a handy overview of the Watsonian vice-county system, including an appendix which lists the dividing lines of the county subdivisions.
For many years the standard guide to our Orthoptera, and still useful, although the distribution maps are now very out of date following the phenomenal range expansions of many of our rarer coastal species during the last few decades.
An update was published in 1973 in Ent Gazette.
