There is not just one story of silk. In silk is science, history and mythology. In silk is the future. Aarathi Prasad’s Silk is a gorgeous new history weaving together the story of a unique material that has fascinated the world for millennia. Through the scientists who have studied silk, and the biology of the animals from which it has been drawn, Prasad explores the global history, natural history, and future of a unique material that has fascinated the world for millennia.For silk, prized for its lightness, luminosity, and beauty is also one of the strongest biological materials ever known. More than a century ago, it was used to make the first bulletproof vest, and yet science has barely even begun to tap its potential. As the technologies it has inspired – from sutures to pharmaceuticals, replacement body parts to holograms – continue to be developed in laboratories around the world, they are now also beginning to offer a desperately needed, sustainable alternative to the plastics choking our planet.Prasad's Silk is a cultural and biological history from the origins and ancient routes of silk to the biologists who learned the secrets of silk-producing animals, manipulating the habitats and physiologies of moths, spiders and molluscs. Because there is more than one silk, there is more than one story of silk. More than one road, more than one people who discovered it, and wove its threads.From the moths of China, Indonesia and India to the spiders of South America and Madagascar, to the silk-producing molluscs of the Mediterranean, Silk is a book rich in the passionate connections made by women and men of science to the diversity of the animal world. It is an intoxicating mix of biography, intellectual history and science writing that brings to life the human obsession with silk.

A rich and surprising exploration of the intelligence of bees Most of us are aware of the hive mind—the power of bees as an amazing collective. But do we know how uniquely intelligent bees are as individuals? In The Mind of a Bee, Lars Chittka draws from decades of research, including his own pioneering work, to argue that bees have remarkable cognitive abilities. He shows that they are profoundly smart, have distinct personalities, can recognize flowers and human faces, exhibit basic emotions, count, use simple tools, solve problems, and learn by observing others. They may even possess consciousness.Taking readers deep into the sensory world of bees, Chittka illustrates how bee brains are unparalleled in the animal kingdom in terms of how much sophisticated material is packed into their tiny nervous systems. He looks at their innate behaviors and the ways their evolution as foragers may have contributed to their keen spatial memory. Chittka also examines the psychological differences between bees and the ethical dilemmas that arise in conservation and laboratory settings because bees feel and think. Throughout, he touches on the fascinating history behind the study of bee behavior.Exploring an insect whose sensory experiences rival those of humans, The Mind of a Bee reveals the singular abilities of some of the world’s most incredible creatures.

A beautiful and unique guide to Britain’s bees – a perfect gift for all gardeners and nature loversBees are much-loved and hugely important creatures. But most of us know next to nothing about them.

Once you start to notice bees, sitting in the garden or going for a stroll will never be the same.This handy little guide is the perfect way to start the journey. It’s beautifully illustrated and has a delightful and thoughtful text by one of Britain’s leading bee experts, Dave Goulson, author of the best-selling ‘Garden Jungle’.Discover mason bees and mining bees, cuckoo bees and carder bees, even a couple of convincing bee impersonators. Learn to distinguish your white-tailed bumblebee from your buff-tailed bumblebee, your pantaloon bee from your hairy-footed flower bee.

Honeybees make decisions collectively - and democratically. Every year, faced with the life-or-death problem of choosing and traveling to a new home, honeybees stake everything on a process that includes collective fact-finding, vigorous debate, and consensus building. In fact, as world-renowned animal behaviorist Thomas Seeley reveals, these incredible insects have much to teach us when it comes to collective wisdom and effective decision making. A remarkable and richly illustrated account of scientific discovery, "Honeybee Democracy" brings together, for the first time, decades of Seeley's pioneering research to tell the amazing story of house hunting and democratic debate among the honeybees. In the late spring and early summer, as a bee colony becomes overcrowded, a third of the hive stays behind and rears a new queen, while a swarm of thousands departs with the old queen to produce a daughter colony. Seeley describes how these bees evaluate potential nest sites, advertise their discoveries to one another, engage in open deliberation, choose a final site, and navigate together - as a swirling cloud of bees - to their new home.Seeley investigates how evolution has honed the decision-making methods of honeybees over millions of years, and he considers similarities between the ways that bee swarms and primate brains process information. He concludes that what works well for bees can also work well for people: any decision-making group should consist of individuals with shared interests and mutual respect, a leader's influence should be minimized, debate should be relied upon, diverse solutions should be sought, and the majority should be counted on for a dependable resolution. An impressive exploration of animal behavior, "Honeybee Democracy" shows that decision-making groups, whether honeybee or human, can be smarter than even the smartest individuals in them.

Richly illustrated and delightfully written, Journey to the Ants combines autobiography and scientific lore to convey the excitement and pleasure the study of ants can offer. Bert Hölldobler and E. O. Wilson interweave their personal adventures with the social lives of ants, building, from the first minute observations of childhood, a remarkable account of these abundant insects’ evolutionary achievement.

A richly illustrated natural history of ants, covering their diversity, ecology, anatomy, behavior, and morePlentiful and familiar, ants make up an estimated one-third of the world’s insect biomass and can be found in virtually every part of the globe, from rain forest canopies to city sidewalks. But their importance is about more than numbers: ants are fundamental species in a range of habitats and their interactions with plants, fungi, and other animals ensure the survival of many fragile and complex ecosystems. This beautifully illustrated book explores the extraordinary diversity of ants and offers insights into their elaborate social systems, investigating the key collective and competitive behaviors that operate within their varied colony structures.Featuring exceptional close-up photographs and clearly organized thematic chapters, the book covers anatomy, evolution, life cycle, ecology, and other important topics. Each chapter also features profiles of standout genera, chosen for their fascinating characteristics, including Leafcutter Ants, who build nests containing up to 7,000 chambers; Pugnacious Ants whose colonies can destroy populations of crabs within hours; and Honeypot Ants whose worker caste store food in their stomachs for other colony members to consume. Drawing on current research, Ants offers an inviting and accessible introduction to these remarkable insects.Includes more than 200 stunning color photographs, plus infographics and diagramsPresents full profiles of 42 iconic genera from across the worldFeatures clearly structured thematic chapters

Physiological Systems in Insects, Fourth Edition explores why insects have become the dominant animals on the planet. Sections describe the historical investigations that have led us to our current understanding of insect systems. Integrated within a basic physiological framework are modern molecular approaches that provide a glimpse of the genetic and evolutionary frameworks that testify to the unity of life on earth. This updated edition describes advances that have occurred in our understanding of hormone action, metamorphosis, and reproduction, along with new sections on the role of microbiomes, insecticide action and its metabolism, and a chapter on genetics, genomics and epigenetic systems.

The book represents a collaborative effort by two internationally known insect physiologists who have instructed graduate courses in insect physiology. As such, it is the ideal resource for entomologists and those in other fields who may require knowledge of insect systems.

Presents updated information on key physiological principles Covers detailed and instructive figures for visual enhancement Provides flowing text without the interruption of citations Includes evolutionary considerations throughout, also providing a discussion on the implications of molecular techniques and discoveries Encourages further reading with a complete bibliography at end of each chapter

Dinosaurs, however toothy, did not rule the earth - and neither do humans. But what were and are the true potentates of our planet? Insects, says Scott Richard Shaw - millions and millions of insects. Starting in the shallow oceans of ancient earth and ending in the far reaches of outer space - where, Shaw proposes, insect-like aliens might have achieved similar preeminence - Planet of the Bugs spins a sweeping account of insects' evolution from humble arthropod ancestors into the bugs we know and love (or fear and hate) today. Leaving no stone unturned, Shaw explores how evolutionary innovations such as small body size, wings, metamorphosis, and parasitic behavior have enabled insects to disperse widely, occupy increasingly narrow niches, and survive global catastrophes in their rise to global dominance.Through buggy tales at turns bizarre and comical - from caddisflies that construct portable houses or weave silken aquatic nets to trap floating debris, to parasitic wasp larvae that develop in the blood of host insects and, by storing waste products in their rear ends, are able to postpone defecation until after they emerge - he not only unearths how changes in our planet's geology, flora, and fauna contributed to insects' success, but also how, in return, insects came to shape terrestrial ecosystems and amplify biodiversity. Indeed, in his visits to modern earth's hyperdiverse rain forests to highlight the current insect extinction crisis, Shaw reaffirms just how critical these tiny beings are to planetary health and human survival. In this age of honeybee die-offs and bedbugs hitching rides in the spines of library books, Planet of the Bugs charms with humor, affection, and insight into the world's six-legged creatures, revealing an essential importance that resonates across time and space.

Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants possess defences that are effective against almost all herbivorous insect species. Host-plant specialization, observed in over 80% of these animals, appears to be an effective adaptation to breach these defence systems. The mechanisms underlying plant defence to invading herbivores on the one side, and insect adaptations to utilize plants for nutrition, defence and shelter on the other, are the main subjects of this book. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well. For insects, they include complex bevioural adaptations and their underlying sensory systems (with their implications for learning and nutritional plasticity), as well as the endocrinological aspects of life cycle synchronization with host-plant phenology.Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels and explicitly puts these in the context of both ecological interactions and evolutionary processes. In doing so, it uncovers the highly intricate antagonistic as well as mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production.This multidisciplinary approach will appeal to students in biology, agricultural entomology, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects.

A highly illustrated and authoritative introduction to the world’s OrthopteraGrasshoppers, locusts, crickets, bush crickets, and katydids make up the order of insects known as Orthoptera. Although there are about 30,000 species of Orthoptera around the world, many people pay little attention to them and even scientists know relatively little about them. Yet the world of grasshoppers is a fascinating and diverse one. In this richly illustrated book, leading researchers from around the world detail the many facets of these insects, including their evolution, life cycles, and mating behavior. The book presents interesting facts and stories about species such as monkey hoppers, Cooloola monsters, king crickets, wetas, and sandgropers. It also describes efforts to protect grasshoppers and the relationship between humans and these insects.The book features four main sections:Orthoptera in space and time: fossil record, evolution, and systematicsThe biology of Orthoptera: life cycle, ecology, and bioacousticsThe diversity of Orthoptera by geographic regionOrthoptera and humans: locusts, Orthoptera as food, Orthoptera as pets, and conservation

Beekeeping is a sixteen-billion-dollar-a-year business. But the invaluable honey bee now faces severe threats from diseases, mites, pesticides, and overwork, not to mention the mysterious Colony Collapse Disorder, which causes seemingly healthy bees to abandon their hives en masse, never to return. In The Quest for the Perfect Hive, entomologist Gene Kritsky offers a concise, beautifully illustrated history of beekeeping, tracing the evolution of hive design from ancient Egypt to the present. Not simply a descriptive account, the book suggests that beekeeping's long history may in fact contain clues to help beekeepers fight the decline in honey bee numbers. Kritsky guides us through the progression from early mud-based horizontal hives to the ascent of the simple straw skep (the inverted basket which has been in use for over 1,500 years), from hive design's Golden Age in Victorian England up through the present. He discusses what worked, what did not, and what we have forgotten about past hives that might help counter the menace to beekeeping today. Indeed, while we have sequenced the honey bee genome and advanced our knowledge of the insects themselves, we still keep our bees in hives that have changed little during the past century. If beekeeping is to survive, Kritsky argues, we must start inventing again. We must find the perfect hive for our times. For thousands of years, the honey bee has been a vital part of human culture. The Quest for the Perfect Hive not only offers a colorful account of this long history, but also provides a guide for ensuring its continuation into the future.

A beautifully illustrated introduction to the incredible variety of bees from around the worldWhen many people think of bees, they are likely to picture the western domesticated honey bee, insects that live in large, socially complex societies inside a hive with a single queen and thousands of workers. But this familiar bee is just one of more than 20,000 species of bees—and almost none of the others is anything like it. In Bees of the World, Laurence Packer, one of the world’s foremost experts on wild bees, celebrates the amazing diversity of bees—from size and appearance to nests and social organization.Providing clear, accurate accounts of the seven bee families, Bees of the World presents all the key information on generic characteristics, habits, and habitat, illustrated with incredible and often rare photographs that show bees in their natural habitats—foraging, nesting, raising their young, and more. The book reveals the secrets of these extraordinary insects as well as their importance in the global ecosystem and the ways humans can help protect them.Provides a richly illustrated exploration of bees from around the worldExamines more than 100 genera of bees, giving a taste of the remarkable breadth of bee appearance and biologyExplores bee anatomy, behavior, classification, evolution, life cycle, and habitats

Insects represent over half of the planet’s biological diversity. This popular textbook provides a comprehensive introduction to this extraordinary diversity, and places entomology central to the theory and practice of evolutionary and ecological studies.Fully revised, this fifth edition opens with a chapter concerning the popular side of insect studies, including insects in citizen science, zoos and butterfly houses, and insects as food for humans and animals. Key features of insectstructure, function, behaviour, ecology and classification are integrated with appropriate molecular studies.  Much of the book is organized around major biological themes: living on the ground, in water, on plants, in colonies, and as predators, parasites/parasitoids and prey insects. A strong evolutionary theme is maintained throughout.There is major revision to the chapter on systematics and a new chapter, Insects in a Changing World, includes insect responses to, and the consequences of, both climate change and human-assisted global alterations to distributions. Updated ‘Taxoboxes’ demonstrate topical issues and provide concise information on all aspects of each of the 28 major groupings (orders) of insects, plus the three orders of non-insect hexapods. New boxes describe a worrying increase in insect threats to landscape and commercial trees (including eucalypts, palms and coffee) and explain the value of genetic data, including evolutionary developmental biology and DNA barcoding, in insect biodiversity studies. The authors maintain the clarity and conciseness of earlier editions, and extend the profuse illustrations with new hand-drawn figures. Over 50 colour photographs, together with the informative text and an accompanying website with links to video clips, appendices, textboxes and further reading lists, encourage a deeper scientific study of insects. The book is intended as the principal text for students studying entomology, as well as a reference text for undergraduate and graduate courses in the fields of ecology, agriculture, fisheries and forestry, palaeontology, zoology, and medical and veterinary science.

For many of us, the buzzing of a bee elicits panic. But the next time you hear that low droning sound, look closer: the beehas navigated to this particular spot for a reason using a fascinating set of tools. She may be using her sensitive olfactoryorgans, which provide a 3D scent map of her surroundings. She may be following visual landmarks or instructionsrelayed by a hive-mate. She may even be tracking electrostatic traces left on flowers by other bees. What a Bee Knows:Exploring the Thoughts, Memories, and Personalities of Bees invites us to follow bees’ mysterious paths and experience theiralien world.Although their brains are incredibly small—just one million neurons compared to humans’ 100 billion—bees haveremarkable abilities to navigate, learn, communicate, and remember. In What a Bee Knows, entomologist StephenBuchmann explores a bee’s way of seeing the world and introduces the scientists who make the journey possible. We travel into the field and to the laboratories of noted bee biologists who have spent their careers digging into the questionsmost of us never thought to ask (for example: Do bees dream? And if so, why?). With each discovery, Buchmann’sinsatiable curiosity and sense of wonder is infectious.What a Bee Knows will challenge your idea of a bee’s place in the world—and perhaps our own. This lively journey into abee’s mind reminds us that the world is more complex than our senses can tell us.

‘A funny and beautifully written welcome to the enigmatic, weird and wonderful world of wasps’ DAVE GOULSON, author of SILENT EARTHThere may be no insect with a worse reputation than the wasp, and none guarding so many undiscovered wonders. Where bees and ants have long been the darlings of the insect world, wasps are much older, cleverer and more diverse. They are the bee’s evolutionary ancestors – flying 100 million years earlier – and today they are just as essential for the survival of our environment. A bee, ecologist Professor Seirian Sumner argues, is just a wasp that has forgotten how to hunt. For readers of Entangled Life, Other Minds and The Gospel of Eels, this is a book to upturn your expectations about one overlooked animal and the wider architecture of our natural world.With endless surprises, this book might teach you about the wasps that spend their entire lives sealed inside a fig, about stinging wasps, about parasitic wasps, about wasps that turn cockroaches into living zombies, about how wasps taught us to make paper.It offers up a maligned insect in all its diverse, unexpected splendour; as both predator and pollinator, the wasp is an essential pest controller worldwide. Inside their sophisticated social worlds is the best model we have for the earth’s major evolutionary transitions. In their understudied biology are clues to progressing medicine, including a possible cure for cancer.The closer you look at these spurned, winged insects – both custodians and bouncers of our planet – the more you see. Their secrets have so far gone mostly untapped, but the potential of the wasp is endless.
