1. There are more than 2,000 species of fireflies, a type of beetle. Despite their name, only some species produce adults that glow. Fireflies in the western United States, for example, lack...

Like all other beetles, lightning bugs have hardened forewings called elytra, which meet in a straight line down the back when at rest. In-flight, fireflies hold the elytra out for balance, relying on their membranous hindwings for movement. These traits place fireflies squarely in the order Coleoptera.
An incandescent light bulb gives off 90% of its energy as heat and only 10% as light, which you'd know if you've touched one that's been on for a while. If fireflies produced that much heat when they lit up, they would incinerate themselves. Fireflies produce light through an efficient chemical reaction called chemiluminescence that allows them to ...
Fireflies don't put on those spectacular summer displays just to entertain us. You're eavesdropping on the firefly singles bar. Male fireflies cruising for mates flash a species-specific pattern to announce their availability to receptive females. An interested female will reply, helping the male locate her where she's perched, often on low vegetat...
We don't often see fireflies before they reach adulthood, so you might not know that fireflies glow in all life stages. Bioluminescence begins with the egg and is present throughout the entire life cycle. All firefly eggs, larvae, and pupae known to science can produce light. Some firefly eggs emit a faint glow when disturbed. The flashing part of ...
The firefly begins life as a bioluminescent, spherical egg. At the end of the summer, adult females lay about 100 eggs in soil or near the soil surface. The worm-like larva hatches out in three to four weeks and throughout the fall hunts prey using a hypodermic-like injection strategy similar to that of bees. Larvae spend the winter below ground in...
Fireflies are known for their blinking light signals, but not all fireflies flash. Some adult fireflies, mostly those in western North America, don't use light signals to communicate. Many people believe that fireflies don't exist west of the Rockies since flashing populations are rarely seen there, but they do.
Firefly larvaeare carnivorous predators, and their favorite food is escargot. Most firefly species inhabit moist, terrestrial environments, where they feed on snails or worms in the soil. A few Asian species use gills to breathe underwater, where they eat aquatic snails and other mollusks. Some species are arboreal, and their larvae hunt tree snail...
What adult fireflies eat is largely unknown. Most don't seem to feed at all, while others are believed to eat mitesor pollen. We do know that Photuris fireflies eat other fireflies. Photuris females enjoy munching on males of other genera. These Photuris femmes fatalesuse a trick called aggressive mimicry to find meals. When a male firefly of anoth...
Scientists have developed remarkable uses for firefly luciferase, the enzymethat produces bioluminescence in fireflies. It has been used as a marker to detect blood clots, to tag tuberculosis virus cells, and to monitor hydrogen peroxide levels in living organisms. Hydrogen peroxide is believed to play a role in the progression of some diseases, in...
Imagine thousands of fireflies lighting up at the same time, over and over, from dusk to dark. Simultaneous bioluminescence, as it is called by scientists, occurs in just two places in the world: Southeast Asia and Great Smoky Mountains National Park. North America's lone synchronous species, Photinus carolinus, puts on its light show annually in l...
There are about 2,000 firefly species. These insects often live in humid regions of Asia and the Americas, where they mostly feast on plant pollen and nectar. Firefly larvae—recently hatched...
- Fireflies Are Not Actually Flies. Contrary to what their name suggests, lightning bugs don't belong to the same family as flies. Rather, they're nocturnal members of the family Lampyridae, within the order Coleoptera, which also contains ladybugs, emerald ash borers, and boll weevils.
- Their Bioluminescence Is Caused by a Chemical Reaction. Luciferin is an enzyme inside the firefly's abdomen and tail area that, when combined with oxygen, calcium, and adenosine triphosphate, creates light.
- They're Incredibly Efficient. The light produced by fireflies is the most efficient light on earth. According to The National Wildlife Federation, almost 100 percent of the energy from this chemical reaction is emitted as light, whereas an incandescent lightbulb emits only 10 percent of its energy as light while the other 90 percent is lost as heat.
- Fireflies in the Western U.S. Don't Light Up. Fireflies live in temperate and tropical habitats all over the world, on every continent but Antarctica.
- Extraction of Luciferase: Credit Goes to Firefly. Luciferase is a light-producing enzyme that oxidizes its substrate called 'Luciferin' in an energetic process.
- Most Efficient Light Producer. Their light is the most efficient in the world. That's why scientists refer to their light as "cold light". An incandescent bulb produces light by emitting 10% of its energy, and the rest is heat.
- They Attract Their Mates Through Light. Sound strange! But yes, it is true. Fireflies emit light to attract mates. Mostly, both males and females light up, but in some species, only one sex glows.
- They Defend Themselves Through 'Reflex Bleeding' Reflect bleeding is also known as "Autohaemorraghing". It is the ejection of blood from the animal's body.
FACTS ABOUT FIREFLIES. Interested in learning more about fireflies? Here are a few fascinating. facts you may not know. Fireflies talk to each other with light. Fireflies emit light mostly to attract mates, although they also communicate. for other reasons as well, such as to defend territory and warn predators. away.
Jun 10, 2022 · No summer evening is complete without watching fireflies. Here are some fun facts about lightning bugs—which are technically beetles, not bugs.
