Science Friday: If you’re lucky enough to live where fireflies flash at night, then you have surely seen their magical illuminations on warm summer evenings. But did you know that by observing fireflies while they are flashing, you can learn to communicate with them? If you haven’t already, watch the Science Friday Video “In a Flash: Firefly Communication” for a little background on how fireflies use light to communicate:

By watching and comparing fireflies all across the country, scientists have been able to map out the unique flash patterns of male and female fireflies of different species. Dr. John E. Lloyd, an entomologist at the University of Florida, featured in the video above, was one of the first to do this extensively for North American species of firefly in the genus Photinus.
