What are insects and spiders really, and how have they survived on our planet for millions of years, remaining relatively unchanged? This book explores the world of entomology and reveals the secrets that hide there, examining the anatomy, behaviour, the mysterious world of insect societies, habitat, seasonal cycles and ways to safely track down species, from beetles and butterflies to grasshoppers and honeybees. A photographic guide comes complete with ranges, maps, fact entries, and any information pertinent to the species' protection. Also included is a glossary and appendix of sources.
