Fireflies, the bioluminescent beetles that light up summer evenings, are more diverse than many realize. According to a 2021 review, 44 species of the Lampyridae family are found across Vermont, New Hampshire, Maine, Massachusetts, and New York. Globally, there are roughly 2,400 described species.
While many fireflies produce light as a warning signal to predators, the glow has also evolved into mating displays. Some species, like the "superb ghost" and "creekside tree blinker," live in the region. The pattern of flashing helps individuals identify their own kind, and in some places, thousands of fireflies sync up their flashes.
Not all fireflies glow, and females of the genus Photuris, including Fairchild's predator, mimic the flashes of other species to lure and eat males. Adult fireflies generally do not eat, though some sip nectar.
Little is known about firefly population health, but habitat loss, light pollution, and pesticides are major threats. The Xerces Society's Firefly Atlas project encourages people to report sightings to help track populations. Residents of the Northeast Kingdom can submit observations on the project's website.
