The Book

“If you love fireflies, then I wrote this book for you.”

Their ethereal beauty has inspired wonder and delight for centuries.
Yet for most of us, fireflies remain shrouded in mystery…

How do these creatures make light? What do baby fireflies look like?

What are they saying with all that flashing – and to whom?

Are fireflies really disappearing?

Silent Sparks: The Wondrous World of Fireflies appeals to curious nature lovers of all ages, and abounds with stunning images. Inside you’ll discover stories of fireflies’ gluttonous childhoods, their seductive sex lives, elaborate gifts, treacherous poisons, and dangerous deceits. You can find this celebration of firefly science and wonder at your local bookstore, or here or here. And in the book’s Chapter Notes, there’s lots more information and links to explore!
