"Summer's Joy Dimmed: Light Pollution Threatens Courting Fireflies"

Artificial lights, such as street lamps and LEDs, are disrupting the courtship and mating behaviors of fireflies, leading to a decline in their populations. Female fireflies are particularly affected by the bright lights, as they have difficulty seeing the males' signals. The increasing use of artificial lights, including LEDs, has made the night sky twice as bright in the last decade, negatively impacting nocturnal fireflies. Certain firefly species are already classified as threatened, and researchers estimate that nearly one-third of the 170 firefly species in North America are at risk of extinction. To help fireflies, people can create suitable habitats by leaving leaves in their yards for larvae, limiting pesticide use, and reducing light pollution by turning off unnecessary lights.
