In The Descent of Man, Charles Darwin proposed that an ant’s brain, no larger than a pin’s head, must be sophisticated to accomplish all that it does. Yet today many people still find it surprising that insects and other arthropods show behaviors that are much more complex than innate reflexes. They are products of versatile brains which, in a sense, think.

Fascinating in their own right, arthropods provide fundamental insights into how brains process and organize sensory information to produce learning, strategizing, cooperation, and sociality. Nicholas Strausfeld elucidates the evolution of this knowledge, beginning with nineteenth-century debates about how similar arthropod brains were to vertebrate brains. This exchange, he shows, had a profound and far-reaching impact on attitudes toward evolution and animal origins. Many renowned scientists, including Sigmund Freud, cut their professional teeth studying arthropod nervous systems. The greatest neuroanatomist of them all, Santiago Ramón y Cajal—founder of the neuron doctrine—was awed by similarities between insect and mammalian brains.

Writing in a style that will appeal to a broad readership, Strausfeld weaves anatomical observations with evidence from molecular biology, neuroethology, cladistics, and the fossil record to explore the neurobiology of the largest phylum on earth—and one that is crucial to the well-being of our planet. Highly informative and richly illustrated, Arthropod Brains offers an original synthesis drawing on many fields, and a comprehensive reference that will serve biologists for years to come.

Throughout the Middle Ages, enormously popular bestiaries presented people with descriptions of rare and unusual animals, typically paired with a moral or religious lesson. The real and the imaginary blended seamlessly in these books—at the time, the existence of a rhinoceros was as credible as a unicorn or dragon. Although audiences now scoff at the impossibility of mythological beasts, there remains an extraordinary willingness to suspend skepticism and believe wild stories about nature, particularly about insects and their relatives in the Phylum Arthropoda.

In The Earwig’s Tail, entomologist May Berenbaum and illustrator Jay Hosler draw on the powerful cultural symbols of these antiquated books to create a beautiful and witty bestiary of the insect world. Berenbaum’s compendium of tales is an alphabetical tour of modern myths that humorously illuminates aerodynamically unsound bees, ear-boring earwigs, and libido-enhancing Spanish flies. She tracks down the germ of scientific truth that inspires each insect urban legend and shares some wild biological lessons, which, because of the amazing nature of the insect world, can be more fantastic than even the mythic misperceptions.
