Your backyard firefly displays may not be lighting up the night like they used to. According to experts, populations of these beloved bioluminescent beetles are declining across the United States.
"It's tough to pinpoint the magnitude of that decline," said Christie Bahlai, Ph.D., a population ecologist and associate professor at 5X社区. While firefly booms and busts are natural, recent studies and observations point to an overall downward trend over the past decade.
The main culprits? According to , pesticide usage, light pollution and habitat loss are making it harder for fireflies to thrive. But you can help reinvigorate local firefly populations by skipping the pesticides, reducing outdoor lighting, and cultivating areas with moisture, cover and food sources that mimic their natural habitats.
"It's never too late" to create a more welcoming environment for fireflies in your backyard, With some adjustments, you may be able to restore the summer magic of twinkling firefly displays for future generations.
Most importantly, be patient, Balhai said. Populations won鈥檛 rebound overnight, or even in one season, Bahlai says. It takes about six years for a depleted firefly population to rebound from an environmentally bad year, but the results will be worth it.
