In Great Smoky Mountains National Park, a species of synchronous firefly gathers each year and flashes in waves, many blinking at almost the same time.
The display usually happens for a short period around late May and June, and it is so popular that the park runs a lottery for viewing passes.

Synchronous fireflies are also found in parts of Southeast Asia, where whole trees can seem to pulse with light.
