Dragonflies and damselflies are conspicuous insects – many are large and brightly coloured. Here for the first time is a comprehensive guide to the Australian dragonfly fauna. The book includes identification keys not only for adults but also for their larvae, commonly known as ‘mud eyes’ and often used as bait for freshwater fish. With stunning full-colour images and distribution maps, the book covers all 30 families, 110 genera and 324 species found in Australia.Dragonflies are valuable indicators of environmental well-being. A detailed knowledge of the dragonfly fauna and its changes is therefore an important basis for decisions about environmental protection and management. Their extraordinary diversity will interest entomologists and amateur naturalists alike.
