Book excerpt: Whether you're an amateur insect enthusiast, a student or an entomologist, this updated and revised third edition of A Field Guide to Insects in Australia will help you to identify insects from all the major insect groups. With more photographs and up-to-date information, it will enable you to differentiate between a dragonfly and a damselfly or a cricket and a grasshopper. You'll find cockroaches, termites, praying mantids, beetles, cicadas, moths, butterflies, ants and bees. More than 300 colour photographs show the insects in their natural habitat and the line drawings clearly illustrate subtle differences where identification is tricky.
