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 D...

Predaceous diving beetles (Coleoptera: Dytiscidae) constitute one of the largest families of freshwater insects (~ 4,200 species). Although dytiscid adults and larvae are ubiquitous throughout a variety of aquatic habitats and are significant predators on other aquatic invertebrates and vertebrates, there are no compilations that have focused on summarizing the knowledge of their ecology, systematics, and biology. Such knowledge would benefit anyone working in aquatic systems where dytiscids are an important part of the food web. Moreover, this work will allow 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 offers a synthesis of the current knowledge of a variety of topics and will provide future directions for research.

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 ...
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1914 edition. Excerpt: ... EDUCATION FOR MANHOOD The well known and well worn maxim of the poet, Lowell: "New occasions teach new duties, Time makes ancient good uncouth," expressed, with practical shrewdness, a transient phase, rather than the permanent form of truth. Good in the positive, or even in the comparative, degree may, indeed, be limited by circumstances, time and place; but superlative good is of the nature and essence of things eternal. A shallow philosophy emphasizes the evanescent...
