In this summer night of Maine, I was mesmerized by the fireflies in a blueberry field, shining under the Milky Way. Fireflies are incredible insects found on every continent except Antarctica. They communicate in a delicate language of light. They signal for mating, warning the predators presence, and to defend their territory. But for all of these they need natural darkness and we have changed that in many places by our artificial lights. The new intensely bright white-blue LEDs have made it worse. Evidence suggests that light pollution contributes to the decline of firefly population (and many other nocturnal insects) across the globe. Studies found an almost 50% decrease in firefly flashes per minute in the presence of artificial light and that means less mating and less population. Suggested by International Dark Sky Association, people who live away from the city lights can help fireflies talk to each other by using fewer and warmer exterior lights and turning lights off when they aren’t needed (or using motion-sensor lights).
