FIREFLY SONG

A piece of summer magic helps inform a scientific discovery.

Lynn Frierson Faust spent childhood summers with her family in Elkmont, Tennessee, a region situated within the boundaries of the Great Smoky Mountains National Park. There, her family gathered in the summer dark to watch as fireflies lit up the forest in harmony (“Blink! Shine! Twinkle! Pop! Flash!”) before blinking back into darkness. As she grew older, Lynn sought more information about this phenomenon. She consulted the park rangers, the University of Tennessee, the public library—but no one seemed to know about her synchronously flashing fireflies. Finally, she found a biologist who was intrigued by the musical score she’d composed to represent the way the fireflies flashed together. The scientific process of documentation and research took years before the confirmation of Photinus carolinus, “the first documented case of synchronous fireflies in the entire Western Hemisphere.” Paeff succinctly captures the patience and detailed work involved in this kind of study while keeping the sense of wonder in focus. Kim’s painterly art perfectly conveys the deep, leafy green of the forest in summer and the splashes and sparks of light from these bioluminescent creatures. Lynn is white; background characters vary in skin tone.

A wonderful tribute to a citizen scientist who harnessed the power of observation and discovery.
