Moths of the family Arctiidae, with their brilliant coloration, spectacular courtship rituals, and bizarre defenses, are wonders of the natural world. Tiger Moths and Woolly Bears, the first book written about this fascinating group, documents how the adults and larvae of the Arctiidae flourish in a world rife with predators, parasites, and competitors. The contributing authors -- each a recognized expert in the field -- weave together seminal studies on this family's phylogeny and behavior, natural history, chemical communication, mate choice and sexual selection, adaptive coloration, speciation, and more.
