Excerpt from On Aquatic Carnivorous Coleoptera or Dytiscidae Some years ago I commenced a special study of the Dytiscidae, with the Object of increasing the recorded information about this family of beetles. I had been previously, for a considerable period, specially interested in the family, and when beginning my studies, I hoped particularly that I should be able to improve the very imperfect classification in vogue, and I also wished to know whether a detailed knowledge of the varied structural peculiarities of the species would be consistent with the belief that the present condition of these had been reached by a process of gradual modification or evolution, and whether an intimate acquaintance with the intricate relations existing between the diverse components Of the family would render credible the hypothesis that these are descended from a few ancestors or even from a single very remote ancestor. Now that I am Offering to the Royal Dublin Society the work that has occupied me for some years, I feel that I must in the first place make an apology for its imperfections and omissions. I have accomplished but little - so little that, in comparison with what I have left undone, I feel it to be almost as nothing. Our knowledge Of the earlier stages of the life Of Coleoptera, and of their meta morphoses is very imperfect, and in the case Of the aquatic species there are special difficulties in the way of acquiring information of this nature, thus it happens that we know very little of the life histories of the Dytiscidae - so little that it cannot aid at present in the classification of these insects, and I have therefore limited my efforts to producing an arrangement based on the structures of the perfect insect.

The 2nd edition of this comprehensive book provides one of the most complete overviews of the aquatic beetles in the family Dytiscidae, also known as predaceous diving beetles. Dytiscids constitute one of the largest families of freshwater insects with approximately 4,650 named species that come in a variety of sizes, colors, and habitat affinities. Although dytiscid adults and larvae are ubiquitous throughout a variety of aquatic habitats, and are important predators on other aquatic invertebrates and vertebrates, there are no compilations that have focused on summarizing the knowledge on aspects of their ecology, systematics, and biology. Chapters in this book summarize hitherto scattered topics, including their anatomy and habitats, chemical and community ecology, phylogenies and larval morphology including chaetotaxy, sexual systems, predation, dispersal, conservation, and cultural and historical aspects. The 2nd edition offers updates on the newest scientific findings on dytiscids and also includes a new chapter on the subterranean fauna from Australia. The information in this new edition is potentially beneficial to anyone working in aquatic systems where dytiscids are an important part of the food web. Moreover, readers will gain a greater appreciation of dytiscids as model organisms for investigations of fundamental principles derived from ecological and evolutionary theory. Contributed chapters are by authors who are actively engaged in studying dytiscids, and each chapter provides color photos and future directions for research.

The first comprehensive book in more than a century to reveal the diversity and natural history of diving beetles. Among the hundreds of thousands of species of beetles, there is one family, containing some 4,300 species, that stands out as one of the most diverse and important groups of aquatic predatory insects. This is the Dytiscidae, whose species are commonly known as diving beetles. No comprehensive treatment of this group has been compiled in over 130 years, a period during which a great many changes in classification and a near quadrupling of known species has occurred. In Diving Beetles of the World, Kelly B. Miller and Johannes Bergsten provide the only full treatments of all 188 Dytiscid genera ever assembled. Entomologists, systematists, limnologists, ecologists, and others with an interest in aquatic systems or insect diversity will find these extensively illustrated keys and taxon accounts immensely helpful. The keys make it possible to identify all taxa from subfamily to genera, and each key and taxon treatment is accompanied by both photographs and detailed pen-and-ink drawings of diagnostic features. Every genus account covers body length, diagnostic characters, classification, species diversity, a review of known natural history, and world distribution. Each account is also accompanied by a range map and at least one high-resolution habitus image of a specimen. Diving beetles are fast becoming important models for aquatic ecology, world biogeography, population ecology, and animal sexual evolution and, with this book, the diversity of the group is finally accessible.

Excerpt from The Natural History of Aquatic Insects The conditions of life in fresh waters are materi ally different from those afforded by the sea. The chemical difference between fresh and salt waters is of small importance in itself - so small that many animals have been able to adapt themselves gradually to a change from one to the other. A degree of saltness far greater than that of sea-water is perfectly compatible with animal life, as is shown by the fact that Crustacea and Insects are often found quite at home in brine-pits and vats. There are even a few animals, like the Salmon, which can pass sud denly from fresh water to salt, or from salt to fresh.

This is the first exhaustive review of literature on marine insects, which are defined in this volume as those that spend at least part of their life in association with the marine environment. Not only are true insects, such as the Collembola and insect parasites of marine birds and mammals, considered, but also other kinds of intertidal air-breathing arthropods, notably spiders, scorpions, mites, centipedes and millipedes, which live and feed with, or even on, the insects of marine habitats. The chapters, written by leading authorities, are divided into two sections, the first treating primarily ecological aspects, the second dealing with major groups of insects in marine environments.

Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.
