This identification guide will help identity the adults of 73 species of lacewings and allied species (including scorpion flies, snakeflies and alder flies) currently known in the British Isles. Knowledge of the distribution of British lacewings and their allies has expanded significantly in recent years, but there is still more to discover. This field guide - which includes classification lists, confirmatory notes and references - will help you make a positive lacewing identification. Reprint of the 1997 edition with a new cover.
