Some fireflies can flash in unison, and scientists are trying to figure out how – CBC, submitted by Kris Lee

Scientist Orit Peleg has long been fascinated by fireflies that appear to flash their lanterns in synchronicity — but she only just recently got to witness the phenomenon up close.

Peleg and her colleague Raphael Sarfati travelled to the Great Smoky Mountains, which straddle the borders of North Carolina and Tennessee, to witness and film a massive swarm of Photinus carolinus, one of only a handful of firefly species known to synchronize flashes from their lanterns, the light-producing organs.

It’s a mysterious phenomenon that people have long observed with their own two eyes. But it’s never been documented in detail or confirmed scientifically until now.
