Dragonflies (Odonata), represented by over 6000 known species, are unique insects. In more than one feature they differ, at the very first glance, from all other insect superorders including their nearest allies, the mayflies (Ephemeropteroidea). The Zygoptera and Anisoptera, on the other hand, are the dominant groups. Being voracious predators in both immature (aquatic) and adult (aerial) stages they are important elements of all, except the drier (or high alpine) environments in temperate and tropical regions, occupying a position at the apex of the food chain of invertebrate life. Many dragonfly species are tested biological control agents for several disease-transmitting vector mosquitoes, especially Aedes species. They are also ideal organisms to be used as indicators of water pollution and contamination. Many species serve as intermediate hosts of fluke parasites of birds, and thus are important in the transmission of parasitic diseases, especially of domestic poultry and wild ducks. Because of their unique morphology and physiology, dragonflies are used extensively in the study of many biological phenomena. All these subjects are discussed in this unique book comprising twenty three articles written by expert odonatologists from different parts of the world. The book is written in a lucid and comprehensible language, and will likely be useful to both the professional and amateur alike.

Dragonflies are conspicuous insects. Many are large; they fly strongly; most are brightly coloured. As a result, they have been collected extensively. Their larvae are less familiar. 'Mud-eyes', as some are called, are drab, and almost all live in fresh waters, out of sight. They are, perhaps, best known as bait for freshwater fish. The dragonflies constitute a very distinct order of insects, the Odonata. In Australia, two suborders are represented: damselflies (Zygoptera), generally very slender insects, the fore- and hindwings similar in shape and venation and commonly held closed above the body at rest (Figs 46-63), the larvae with external gills on the end of the abdomen (Figs 4A-C, E); and dragonflies proper (Anisoptera), stouter, stronger-flying insects, the fore- and hindwings more or less dissimilar in shape and venation and commonly held spread at rest (Figs 64-101), the larvae with internal, rectal gills (see Chapter 2). Living representatives of the third suborder (Anisozygoptera) are confined to Japan and the Himalayas. The term 'dragonfly' is commonly applied to the entire order.

While we were preparing our book The Naming of Australia's Dragonflies, each of us consulted the etymologies given in A Checklist of North American Odonata: including English name, etymology, type locality, and distribution by Dennis R. Paulson & Sidney W. Dunkle (2012). When we met for the first time at the European Congress of Odonatology (2016) in Tyringe, Sweden, amongst our many conversations we agreed that we had found some entries which could warrant a review. Also recent work by Matti Hämäläinen had shed additional light on some people commemorated with an eponym. We contacted Dennis, the senior author of the checklist, and offered to provide amendments for some of the definitions, and he readily agreed. With this encouragement a number of amendments were suggested for inclusion in the next edition of the checklist. However, our research which included perusal of the original description for every taxon, revealed much information that could not be encapsulated in the phrase or sentence to match the checklist format. When assembled, it was fast approaching the size that warranted publication as a book. If a short biography of each author was included, a book it had to be. We have many people to thank for help in finding copies of the more obscure references. Once the etymologies were essentially complete, and we had started on the biographies, Dennis recruited Harold "Hal" White to help with sourcing photographs of American practitioners and to give a point of contact for those entomologists still, or recently, active in this field. Publication and Distribution presented another problem. This was not the sort of work that would be snapped up by a commercial publisher who would then market and distribute it worldwide, and it was not feasible to distribute from somewhere as remote from America as Australia (or Europe). Whilst many people now prefer publications as a pdf, neither of us would be happy if that were the only medium to be made available. Busybird Publishing, who prepared the volume on the Australian taxa, introduced us to the concept of Print On Demand, and that was the solution we had been seeking. In November 2018 a new edition of the Checklist was published which required us to include an extra four species and another author's biography. And here you have the result of that team's work over more than two years.

Dragonflies and damselflies are conspicuous insects: many are large and brightly coloured. They are also valuable indicators of environmental wellbeing. A detailed knowledge of the dragonfly fauna is therefore an important basis for decisions about environmental protection and management. This comprehensive guide to the Australian dragonfly fauna covers eight families of dragonflies and 10 families of damselflies, comprising the 113 genera and 333 species found in Australia. It has been updated with newly identified species and revised family names to reflect new world consensus systematics. Stunning full-colour images and distribution maps are accompanied by identification keys for adults as well as larvae, which are often used as bait for freshwater fish. This second edition of The Complete Field Guide to Dragonflies of Australia also includes illustrations by Albert Orr, one of the most renowned dragonfly illustrators. The extraordinary diversity of dragonflies will interest entomologists and amateur naturalists alike.
