These Fireflies Put on a Synchronized Light Show

There is a species of firefly, synchronous photinus carolinus, that puts on a most unusual show of lights in the Great Smoky Mountains National Park in the USA. In May and June, visitors to the park can sit back and relax in the dark of night to see the synchronous photinus carolinus fireflies sync-up their light patterns. Repeatedly, every single firefly will go dark for one minute, and after one minute, all the fireflies start to blink their little behinds at the same time. Those who come to watch the synchronous photinus carolinus do their synchronized light show must do the following to avoid confusing the fireflies and messing up their light-synchronization: 1. If using a flashlight while following the path that leads to the synchronized firefly show, the flashlight must be covered with blue or red cellophane. 2. Flashlights must always be pointed toward the ground. 3. Flashlights and phones must be off once you have reached the area in which firefly light show will take place. Every year, around 6,000 visitors gather together near the end of May or in early June to watch the synchronized firefly show.
For a few short weeks each year, Elkmont Ghost Town in Smoky Mountains National Park becomes the site of the most magnificent synchronized firefly (Photinus ...

@Corbin5 just realised that there’s a place in my place a river where fireflies do converge at night. People there have made it an ecotourism spot. At night time they have boat rental where they would pass by the place where they converged at night.

Oh, I hope your sister enjoys learning about these fireflies too. Amazing they all go dark for a minute, and then, they all light up at the same time.

Are they the same as glow worms? There are caves in New Zealand where we were taken by boat to watch them light up.

These are adult fireflys which in the US is a type of beetle. The ones in New Zealand caves are a sort of gnat. But both of their larvae is referred to as a glow worm

@cupkitties Yes, as kids we loved a summer night that was filled with what we called lightning bugs. In the USA, glow worms, Ofelia fultoni, can be found in Alabama's Dismals Canyon. They give off a blue-green light.

I hope they do too. I am sure there is a park ranger nearby to monitor things.

@Corbin5 There is surely a park ranger, some people have no manners and they are so selfish. They could ruin a show like this simply to take a video.

Wow! I love it! This reminds me of the fireflies I always saw at night when I was a kid. I don't think they still exist now, but haven't had time since then to check for them. I no longer live in the province and sad to say, there are no fireflies here in the city.
