Fireflies turn a dark summer night into a spellbinding light display. For many, spending an evening in the presence of these bioluminescent creatures and watching them dance and flash in intricate patterns is a cherished summer tradition.
Luckily, fireflies live on every continent apart from Antarctica, and a handful of them are synchronous, meaning the male insects can synchronize their light patterns. If you want to catch the magical light performance of these insects this summer, these are the best destinations for you to visit.
Congaree National Park is another prime firefly destination in the United States. One of just three synchronous firefly species in the US (Photuris frontalis) inhabits the damp forested area of the park. During the mating season, male fireflies start flashing simultaneously to attract females of the same species.
The insects produce light through a chemical reaction and control the flashes by limiting the amount of oxygen that enters the specialized bioluminescent organs in their bellies. The best time to view synchronous fireflies at Congaree National Park is from mid-May to mid-June.

The Allegheny National Forest is the last remaining area of old forest growth in Pennsylvania. The forest features thick woods, rivers, and watersheds that create the perfect hot and humid habitat for 15 different species of firefly that live here, including the synchronous Photinus carolinus and a local species called Photuris pennsylvanica. The period from the fourth Saturday in June to early July is the time with the brightest natural light display.
