The second edition of this popular identification guide is designed to help non-specialists identify the larger (>1mm length) invertebrates found on land throughout the British Isles.An identification key is included to enable non-specialists to identify living animals encountered during field studies in most terrestrial or semi-terrestrial habitats. Designed for use with living specimens, using standard sampling techniques, characters which require considerable expertise, or expensive equipment, have deliberately been avoided. Ecological notes are included for all groups.For the second edition, the taxonomy has been brought fully up to date.
