Fireflies are often thought to be going extinct. While that is partially true, not all species are disappearing. Of the more than 1,700 known species of fireflies, only about 18 are considered threatened. The idea of fireflies vanishing from our lives is still far off. Many people believe they are already gone because they rarely see them, especially in summer when the insects are most active.

Fireflies usually emerge in warm, humid weather, but many are struggling to adapt as the climate changes rapidly. Some migrate to other regions where conditions are more favorable, while others lose their natural habitats altogether. Overall, about 40% of insect species are endangered or facing extinction because of habitat loss and light pollution.

One major reason fireflies are less visible is light pollution. Artificial lighting in neighborhoods disrupts their mating season. Certain species use light signals to attract mates, but excessive outdoor lighting confuses them and interferes with reproduction. This disruption also complicates research on long-term population trends. As fireflies decline, other insects harmful to crops and ecosystems are on the rise.

There are steps people can take to help protect fireflies. Turning off outdoor lights when they are not needed — and closing blinds if indoor lights are on — reduces harmful glare. Planting native vegetation and mowing lawns less frequently can also create friendlier habitats. Petitions to preserve firefly environments are another way to make a difference.
