An accessible but comprehensive overview of beetles, illustrated with 4,500 photographs. Among Stephen Marshall's many other natural history titles are Insects: Their Natural History and Diversity and Flies: The Natural History and Diversity of Diptera, two of the most respected books on the insect world published in the last 20 years. More admirable than the books' rigorous science, however, is that they are wholly suitable for a lay audience, including student readers from high school on. The books have been adopted as classroom texts and assigned as required reading at the university level and are on the references shelves of many practicing entomologists. In Beetles: The Natural History and Diversity of Coleoptera, Marshall has again applied his deep knowledge of the insect world. Comprehensive and packed with 27 pages of richly illustrated keys and 4,500 colour illustrations, it provides the reader with a colourful and enjoyable introduction to the natural history of a huge group of organisms, along with an overview of the diversity of fascinating families included in the group. The subject of this book is an enormous one, since the beetles, or Coleoptera, include almost 400,000 named species. Marshall opens with a description of what makes a beetle a beetle, and then introduces the natural history of the order with copious examples and explanations. Part one of the book includes: 1. Life Histories of Beetles: Form and Function: Eggs; Larvae; Pupae, Prepupae and Cocoons; Adults; Courtship and Mating Behaviors. 2. Defense and Deception: Tanks, Tricks and Coleopteran; Chemical Warfare; Brilliance and Bioluminescence in the Beetles. 3. Freshwater and Marine Beetles: Freshwater beetles; Marine beetles. 4. Beetle Associations with Fungi, Dung and Carrion: Beetles and Fungi; Beetles and Dung; Beetles and Dead Bodies 5. Beetles, Plants and Plant Products: Beetles and Flowers; Phytophagy and Beetle Diversity; Aposematic Beetles and Their Plant Hosts; Beetles as Agricultural and Garden Pests; Beetles and Biological Control of Weeds; Beetles and Trees 6. Beetles and Other Animals: Dangerous Beetles; Coleoptera and Culture; Beetles Indoors; Rare, Endangered and Threatened Beetles; Beetles, Birds and Wild Mammals; Beetles and Other Invertebrates. Part two of Beetles is a guided tour of the diversity of the order, with fascinating stops for all of the world's 180 or so families of beetles as well as most of the significant subfamilies. Thousands of photos, almost all taken in the field by the author, are used to capture the range of form and function in each family, with pages of examples of the popular groups - such as fireflies, tiger beetles, jewel beetles - but also with unique photographs of little-known groups ranging from longlipped beetles to the rarest rove beetles. Essential information about importance, range, behaviour and biology is provided for each group, and easily used photographic keys to most families are provided for those wishing to use the book as an identification guide. The profusely illustrated keys in Beetles, linked to the unprecedented photographic coverage of the world's beetle families and subfamilies, enable readers to identify most families of beetles quickly and accurately, and to readily access information about each family as well as hundreds of distinctive genera and species. Like its companion titles, Insects and Flies, Beetles will be welcomed by the scientific, academic and naturalist communities, including the next generation of students of entomology.

RSPB Spotlight: Ladybirds is packed with eye-catching, informative colour photos, and features succinct, detailed text written by a knowledgeable naturalist. Brightly coloured and pleasingly pattered, ladybirds are among some of our most beloved and familiar invertebrates. Their role in helping to protect our crops by devouring huge numbers of pests has firmly established these tiny, flying beetles as the gardeners' friend. Spotlight Ladybird focuses on the 26 species that are resident in the UK, from the widespread but unusual Orange Ladybird to the rare - and aptly named - Scarce 7-spot Ladybird. Ladybird expert, Richard Comont considers the conservation challenges facing these iconic species, whose populations are now at risk thanks to the threat posed by one of their own, the invasive alien Harlequin Ladybird. And he covers all aspects of ladybirds' biology, from tiny larvae emerging from their oval eggs to large aggregations that converge at specific sites around the world. Richard also examines the natural history and cultural significance of this fascinating group of beetles, from Ladybird Books to Thor. The Spotlight series introduces readers to the lives of our favourite animals with eye-catching colour photos and informative expert text.

Your Guide to Spiders and Their Webs We see webs everywhere, but do you know which spider made each web? And for what purpose? This user-friendly guide by award-winning science teacher and lifelong spider watcher Larry Weber helps you untangle the mystery of spider webs and demystify the many purposes of silk. Did you know that spiders have up to seven silk glands and that each produces a different type of silk? The complex process of building a giant orb web is explained in detail. Over 40 species of spiders and their webs are discussed here in detail, with over 200 color photos and 50 illustrations. Web Watching was a Silver Winner in the Nature & Environment category of the 31st Annual IBPA Benjamin Franklin Awards for excellence in book publishing.

Mosquitos: Species, Distribution and Disease opens with a discussion on the potential use of plant-derived saponins as a natural larvicide to help prevent and control disease outbreaks in mosquito-infested areas. The general background of saponins, examples of saponin-containing plants and the uses of crude saponins are furthermore discussed. The authors develop practical perspectives on controlling tropical disease vectors in an eco-friendly manner. The authors also provide updated lists of the mosquito species present in the eastern states of the Arabian Peninsula, with information on their collection sites and distribution. New records of some adults are published for the first time from Qatar. An investigation of the morbidity of epidemic vector-borne diseases is also considered. Intracellular population dynamics of viruses under a set of biologically sound parameter values are studied, and statistical tools are used to quantify the estimability of model parameters under distinct scenarios. The resulting mathematical model can also be applied in clinical settings where there is a growing body of work on the within-host dissemination of flaviviruses.
