NAVideo by @babaktafreshi | The sparkling lights of synchronous fireflies are seen in the Great Smoky Mountains, first in fast-motion (4x) and then in real-time video. This forest floor in Tennessee is mating habitat for the largest colony in the Western Hemisphere. These fireflies blink in sync and then pause for 7-8 seconds. The benefit of syncing is not exactly clear, but they sync only when lots of other lightning bugs are nearby. Firefly populations are in decline worldwide due to pesticides, loss of habitat, and light pollution. The light signals stop in the presence of bright artificial light. @insidenatgeo
