A photographic field guide to all the common and some unusual species of insects across Britain and Ireland that the keen amateur naturalist is likely to spot, this collection of 1,500 species is illustrated with detailed photographs chosen for their help in identification, including photographs of larvae. Each section is coded with a symbol for easy reference, and differences between similar species are highlighted to avoid confusion.

Insect groups dealt with include butterflies and moths, mayflies, dragonflies, damselflies, grasshoppers, crickets, earwigs, lacewings, bugs, bees, wasps, and ants and beetles, all with keys to ensure accurate identification.
