As you’re exploring the great outdoors or camping out this summer as part of the Great American Campout, stars and campfires may not be the only objects you see emitting light at night. In the August issue, Ranger Rick magazine highlights bioluminescent wildlife like some jellyfish and insects that have the ability to give off light naturally, making them glow in the dark.
Here are a few native bioluminescent wildlife and where you might spot them:
Fireflies in Your Backyard

Found across the eastern United States, these insects, known as lighting bugs, use their light-up tricks to attract mates and meals. The bioluminescent organs in fireflies are found on the underside of the abdomen. In the Great Smoky Mountains of Tennessee, fireflies are known to put on a unique show in the evening where they flash in unison.
Millipedes in California

These creatures produce light from their bodies thanks to a special type of protein. Originally scientists knew that the invertebrates glowed to warn predators that they produce a toxic cyanide, but scientist have also recently discovered that the millipedes glow in the dark as a way to cope with their hot, dry environment.
Dinoflagellates Along the Coast

Not all dinoflagellates glow, but those that do often give off a blue or red glow. Some dinoflagellates have been known to create red tides, which are not healthy for the surrounding aquatic life.

Covering 2,200 acres, this honey mushroom is a wide spreading fungus that eats trees from the bottom up. Most of the fungus is underground, yet it can be seen glowing because parts of the honey fungus extend under the bark of infested trees.
