What States Have Fireflies?

Fireflies are found in all U.S. States, but not all of the species glow, according to Smithsonian Magazine. Fireflies in the western states do not produce light.

Fireflies are found throughout most of the world, including North, Central and most of South America, Europe, Africa, Asia and Australia. Fireflies need moisture and are found in humid areas. In dry areas of the world, they are found in places that retain moisture. Male fireflies flash their lights to attract females. The flashing also warns potential predators of the fireflies’ bitter taste.There are around 2,000 species of firefly, and each species has a unique light pattern.

Firefly lights are yellow, green or orange. Even the larvae of some firefly species glow. According to National Geographic, fireflies produce their glow by combining oxygen with a substance called luciferin contained within special cells at the end of the abdomen.

Firefly larvae are carnivorous and eat snails and insects. They live underground for several years until they mature. Some adult fireflies are also carnivorous and eat other species of fireflies. Most adults eat pollen and nectar, although some adults do not eat at all. One threat to the firefly is urbanization. Fireflies do not migrate, so when their habitat is destroyed, they disappear from that area completely.
