Incorporating an estimated 43,000 definitions, this major reference work is a comprehensive, fully cross-referenced collection of terms, names and phrases used in entomology. It is the only listing that covers insect anatomy, behaviour, biology, ecology, histology, molecular biology, morphology, pest management, taxonomy and systematics. Common names, scientific binomen and taxonomic classifications are provided as well as order, suborder, superfamily, family and subfamily names and diagnostic features of orders and families. With new and updated terms, particularly in molecular biology, phylogeny and spatial technology, this revised new edition of A Dictionary of Entomology is an essential reference for researchers and students of entomology and related disciplines.

Thaddeus William Harris first made his living as a physician and for many years thereafter as Harvard librarian. For six years, he also taught natural history in Harvard College - Henry David Thoreau was one of his students - but his desire for a full-time professorship was never realized.

With 32 pages of full-color inserts and black-and-white illustrations throughout. From one of our most highly regarded historians, here is an original and engrossing chronicle of nineteenth-century America's infatuation with butterflies—“flying flowers”—and the story of the naturalists who unveiled the mysteries of their existence. A product of William Leach's lifelong love of butterflies, this engaging and elegantly illustrated history shows how Americans from all walks of life passionately pursued butterflies, and how through their discoveries and observations they transformed the character of natural history. In a book as full of life as the subjects themselves and foregrounding a collecting culture now on the brink of vanishing, Leach reveals how the beauty of butterflies led Americans into a deeper understanding of the natural world.
