Because of the flashes of light they naturally produce. The answer is that fireflies contain an organic compound in their abdomens called luciferin. As air rushes into the abdomen, it reacts with the luciferin. A chemical reaction gives off the familiar glow of a firefly. This light is sometimes called “cold light” because it generates so little heat.

The firefly can regulate the airflow into the abdomen to create a pulsating pattern. “Fireflies on top of the wave of grass and overflowing. Fireflies (or lightning bugs, as they are called in some parts in the United States) are found everywhere in the world, usually in marshes and forests; places that have enough food for the firefly's young. These bugs are called fireflies. When you look close-up, you can see that fireflies have soft bodies, compound eyes and a bright, glowing rear end. The firefly's larvae look almost exactly like fully grown fireflies, except that they don't have the compound eyes the adults have. You see, fireflies contain a chemical in their abdomen called luciferin. When that chemical combines with oxygen and with an enzyme called luciferase, the ensuing chemical reaction causes their abdomen to light up. Some females will glow to lure a male to her and then — chomp! — he becomes dinner. The final reason that fireflies glow is to deter predators. Fireflies are filled with chemicals called lucibufagins, which is hard to say and even harder to swallow — they taste terrible. When a predator tastes a firefly, it learns to associate the glow with the bad taste. So the firefly’s glow actually warns would-be predators to stay away. There you have it, folks Fireflies are not flies at all, but they are kinds of beetles. They are also called lightning bugs. Firefly eggs hatch into little wormlike creatures called larvae. Some kinds of larvae glow in the dark, and those that do are called glowworms. The glowworms eat very small creatures such as other insects, snails, and slugs. Some adult fireflies also eat other insects. Some eat pollen and other flower parts, and some probably do not eat anything at all. Here are 10 cool facts about fireflies. 1. Fireflies, also called lightning bugs, are neither flies nor bugs. Fireflies are actually beetles. Like all other beetles, they have hardened forewings called elytra, which meet in a straight line down the back when at rest.  The distress signal doesn't always have the desired outcome. Turpin says that there is a species of firefly that is a predator, called the femme fatale, because the female also eats her mate. One night we were out observing fireflies, and a firefly got caught in a spider's web. The spider began wrapping it up, and it was flashing its distress signal as hard as it could.  Description: There are a number of different species of fireflies, none of which are actually flies—they’re beetles! They get the names “firefly” and “lightning bug” because of the flashes of light they naturally produce. This phenomenon is called bioluminescence, and the bioluminescent organs in fireflies are found on the underside of the abdomen. A similar group of organisms are glowworms. The term “glowworm” can refer to firefly larva or wingless adult females—some of which are not in the firefly family Lampyridae. Both glowworms and fireflies are bioluminescent. The important distinction is that fireflies have wings and glowworms do not.  Next time you see a firefly, keep in mind that its flickering isn’t just a wonder of the night. It’s also a unique, and sometimes deadly, language of love. View larger. | Fireflies in May 2015 – just as the big 2015 firefly season was getting revved up – by Matt Pollock.
