The fireflies synchronous flash or light patterns are part of their mating display and usually include greenish-yellow and bluish lights. Although difficult to photograph or film, the flashing pattern includes 5-8 synchronous bursts of light, followed by complete darkness for about 5 seconds. The fireflies do not always flash in unison. They may also flash in waves across hillsides, and at other times will flash randomly. The show resembles a combination of stars falling and fireworks exploding!
