Fireflies are disappearing. Here’s why — and what you can do to help.

Fireflies were a source of great pleasure when I was kid. My friends and I would chase them through our yards on summer nights, catching them in our palms and delicately moving them to mason jars, where they’d light up our bedrooms.

But now, fireflies are disappearing on a much larger scale. For years scientists have “been warning that the world’s estimated 2,000 species of fireflies are dwindling.” And it’s not because of awful kids.

The problem, as always, is other human behavior, including the use of pesticides and artificial lighting and the destruction of firefly habitat. Fireflies — or lightning bugs — thrive in meadows, woods, and along bodies of water, all of which are shrinking because of our sprawl. Urbanization, it seems, is killing the firefly.

They’re not only being harmed directly by human development, but indirectly by the effects of human-caused climate change. Invasive species that thrive in a warmer climate and drought destroy even more of their habitat.
