A Key to the Major Groups of British Terrestrial Invertebrates by Stephen Tilling (Paperback)

This key has been designed so that non-specialists can identify living animals, in most terrestrial and non-terrestrial habitats, using equipment no more than a hand lens and a ruler. It covers all terrestrial invertebrates which might be found in the field in the British Isles, including introduced groups such as stick insects and scorpions. Morphological and ecological notes are provided for all groups.
