Why do fireflies flash their lights on and off, on and off? That’s what four curious kids want to know. Biologist Sara Lewis has studied fireflies for decades, and she’s cracked the code of their spectacular light displays. She explains why fireflies light up at night with a story of an undercover experiment. Sara tells us how she “spoke firefly” and learned that female fireflies are surprisingly hard to please.
