Fireflies live in various habitats. Many species thrive in forests, fields
or the margins between them. Some live in more arid areas, but they typically
follow the rainy season. Fireflies are found all over the world, from
North and South America to Europe and Asia.
Most firefly species have one thing in common: standing water.
They live near ponds, streams, marshes, rivers and lakes, but they don’t
need a lot of water to get by. Vernal pools and small depressions that
hold water during firefly mating season can all provide the habitat fireflies
need. Most firefly species live at the margins where forest or field meet
Scientists aren’t completely sure what most species of fireflies
eat. It’s probable that firefly larvae feed on different prey
from that of adult fireflies. The larvae are believed to be carnivorous,
living off smaller insects, snails and slugs. Adult fireflies may also
live on other insects, as well as pollen and plants, but it’s possible
that some species don’t eat anything—their lifespan is only a few weeks
long. But scientists believe fireflies thrive in wet areas because their
prey does as well—including other insects and insect larvae, slugs and
Fireflies love humid, warm environments. In the U.S.,
almost no species of fireflies are found west of Kansas—although there
are also warm and humid areas to the west. Nobody is sure why this is.
There are many species of fireflies throughout the world, and the most
diversity in species is found in tropical Asia as well as Central and
Fireflies also love long grass. They’re nocturnal, and
during the day they spend most of their time on the ground. At night,
they crawl to the tops of blades of grass and fly into tree branches to
signal for mates. Long grass conceals the fireflies better and allows
them a better vantage point for signaling at night, and over-mowing your
lawn may disturb your firefly population.
