    But these tiny insects, once merely a seasonal annoyance, now are capturing headlines worldwide as new information emerges about the diseases they carry, their migratory population, and their growing resistance to pesticides.Harvard professor Andrew Spielman has dedicated his life to understanding this insect, a passion that makes him the perfect guide to their amazing world and the perfect author of this lively, accessible book that offers an intriguing and horrifying mosquito-eye view of nature and man. He explains where mosquitoes breed, and how they die, showing us their natural foes and man-made enemies while explaining the myriad diseases they bring to all corners of the world. Spielman offers colorful examples of how the mosquito has insinuated itself into human history, from the defeat of Sir Francis Drake's fleet to the death of thousands of Frenchmen working on the Panama Canal to the recent widespread West Nile panic in New York City. Filled with little-known facts and illuminating anecdotes that bring this tiny being into larger focus, Mosquito offers fascinating, alarming, and convincing evidence that the sooner we get to know this little creature, the better off we'll be.

    And so, with a scientist's training and a nature lover's boundless enthusiasm, he set out to understand the travails and triumphs of the Canada geese living in the beaver bog adjacent to his home. In The Geese of Beaver Bog, Heinrich takes his readers through mud, icy waters, and overgrown sedge hummocks to unravel the mysteries behind heated battles, suspicious nest raids, jealous outbursts, and more. With deft insight and infectious good humor, he sheds light on how geese live and why they behave as they do. Far from staid or predictable, the lives of geese are packed with adventure and full of surprises. Illustrated throughout with Heinrich's trademark sketches and featuring beautiful four-color photographs, The Geese of Beaver Bog is part love story, part science experiment, and wholly delightful.

    From the world’s most painful hornet, to the flies that transmit deadly diseases, to millipedes that stop traffic, to the “bookworms” that devour libraries, to the Japanese beetles munching on your roses, Wicked Bugs delves into the extraordinary powers of many-legged creatures. With wit, style, and exacting research, Stewart has uncovered the most terrifying and titillating stories of bugs gone wild. It’s an A to Z of insect enemies, interspersed with sections that explore bugs with kinky sex lives (“She’s Just Not That Into You”), creatures lurking in the cupboard (“Fear No Weevil”), insects eating your tomatoes (“Gardener’s Dirty Dozen”), and phobias that feed our (sometimes) irrational responses to bugs (“Have No Fear”). Intricate and strangely beautiful etchings and drawings by Briony Morrow-Cribbs capture diabolical bugs of all shapes and sizes in this mixture of history, science, murder, and intrigue that begins—but doesn’t end—in your own backyard.

    Was this forest once farmland? Was it logged in the past?

Wessels has created a key—a fascinating series of either/or questions—to guide you through the process of analyzing what you see. You’ll feel like a woodland Sherlock Holmes. No walk in the woods will ever be the same.

    They are capable of incredibly complex behavior, even with brains often the size of a poppy seed. How do they accomplish feats that look like human activity— personality, language, childcare—with completely different pathways from our own? What is going on inside the mind of those ants that march like boot-camp graduates across your kitchen floor? How does the lead ant know exactly where to take her colony, to that one bread crumb that your nightly sweep missed? Can insects be taught new skills as easily as your new puppy? Sex on Six Legs is a startling and exciting book that provides answers to these questions and many more. With the humor of Olivia Judson’s Dr. Tatiana’s Sex Advice to All Creation, Zuk not only examines the bedroom lives of creepy crawlies but also calls into question some of our own longheld assumptions about learning, the nature of personality, and what our own large brains might be for.

    But there is an important and simple step toward reversing this alarming trend: Everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity.There is an unbreakable link between native plant species and native wildlife—native insects cannot, or will not, eat alien plants. When native plants disappear, the insects disappear, impoverishing the food source for birds and other animals. In many parts of the world, habitat destruction has been so extensive that local wildlife is in crisis and may be headed toward extinction.Bringing Nature Home has sparked a national conversation about the link between healthy local ecosystems and human well-being, and the new paperback edition—with an expanded resource section and updated photos—will help broaden the movement. By acting on Douglas Tallamy's practical recommendations, everyone can make a difference.
