Discover the fascinating science, surprising behaviors, and summertime magic of fireflies—and learn how you can help these beloved insects thrive.
Few sights feel more magical than fireflies flickering across a warm summer evening. Behind those familiar flashes lies an extraordinary world of chemistry, communication, courtship, and survival. In this new edition of The Fireflies Book, naturalist Brett Ortler offers an entertaining and accessible introduction to one of nature’s most captivating creatures.
Learn how fireflies produce light, why different species use distinctive flashing patterns, and how they control when their lanterns turn on and off. Explore the firefly life cycle, meet synchronized fireflies and blue ghosts, and discover predatory “femme fatales” that mimic the signals of other species. You’ll also find practical guidance for observing fireflies and creating healthier habitats in your own yard.
Engaging, informative, and filled with opportunities for discovery, The Fireflies Book is an illuminating guide for families, educators, gardeners, and anyone who has ever paused to watch the tiny lights dance in the darkness.
