Illuminating the Secret Language of Lightning Bugs

Illuminating the Secret Language of Lightning Bugs: Lightning bug lamps can glow yellow, orange or, as is the case with the ghosts, even shades bordering on electric blue. They can appear as single blinks or long, glowing trails. Some fireflies will flicker when threatened by a predator or caught in a spiderweb. Others light up to compete with rivals or after they’ve been rejected by a suitor. Some females are completely dark, while others offer flickers to let males know they’re on the market.
