Stop what you’re doing and watch this short video taken in Samut Prakan province, Thailand. Turn off the lights, go full screen, and get ready to be blown away by thousands of male fireflies regularly synchronizing their flashes to attract females. They synchronize naturally, although here the fireflies (known as Pteropytx malaccae) have been triggered by some flashing LED lights. This video is part of a 2015 installation work by Robin Meier & Andre Gwerder, it’s called “Synchronicity (Thailand).”

You can also watch some spectacular displays of the U.S. synchronous firefly, Photinus carolinus, which lives parts of North Carolina, Tennessee, and Pennsylvania. You can read more about these traveling synchronizers in Silent Sparks (Chapter 2: Lifestyles of the Stars).
