Scientists document dramatic decline in firefly species as climate change alters breeding cycles and destroys habitats.

Those magical summer evenings filled with twinkling lights dancing across yards and fields are becoming increasingly rare. Firefly populations worldwide have declined by an alarming 60% over the past two decades, with scientists pointing directly to climate change as the primary culprit. Rising temperatures, shifting precipitation patterns, and extreme weather events are disrupting the delicate life cycles these insects have followed for millions of years.
From childhood wonder to crucial ecosystem functions, the loss of fireflies represents far more than just dimmer summer nights. Their decline serves as an early warning signal for broader environmental changes that could reshape the natural world as we know it.
