The lucibufagins make these insects distasteful to their predators. The biggest benefit of light for fireflies is that they can use it to ward off predators. This phenomenon more commonly happens in Southeast Asia but can also occur in Tennessee in June.įireflies Ward off Predators With their Light Around 100% of the energy used in the chemical reaction turns into light, so there is no energy waste.įireflies use this light for synchronized flashy displays. This pigment works with an enzyme, luciferase, to create light in the presence of adenosine triphosphate (ATP), magnesium ions, and oxygen. Some don't mix oxygen with luciferin (a pigment) to produce light with little heat. But they come under the name glowworm, along with several other species. Winged fireflies differentiate themselves from glowworms. Most of them are winged, but the females can be wingless. They belong to the Lampyridae family, a Greek name meaning "to shine." Some fireflies glow, while others may not glow. Here are some interesting lightning bug facts:įireflies are beetles. Not all fireflies contain these steroids. Lucibufagins are toxic chemicals that some animals release when they are in danger.įireflies having lucibufagins usually build a powerful defense against several predators, including bats, mice, and spiders.
So are lightning bugs poisonous? Yes, fireflies can be poisonous to their predators. Some species of fireflies can also release defensive steroids known as lucibufagins. These are usually used in cancer, cystic fibrosis, and cardiac disease research. Lightning bugs contain two special chemicals, luciferase and luciferin. In some species, adults can also be predatory. Larvae of some species also feed on earthworms. They attack other insects, such as snails and slugs, and their larvae to survive. They don't fly as fast as other flies or insects. These insects don't transfer any disease to humans and are harmless. Lightning bugs don't have pincers, so they can't bite. There is no specific habitat for fireflies as they are scattered everywhere. They can be found in parks, gardens, wooded areas, and meadows in the evening and night. Lightning bugs usually live in temperate and tropical areas in every corner of the world except Antarctica. Male fireflies use flashes to signal females for mating. You can easily identify males and females due to these flashes.
Some species may also flash at the same time. The light intensity and pattern may vary from one species to another. They produce cold light as there is no heat produced in the process. These light-producing organs are present under their abdomens.
Male and female fireflies create reddish-orange to greenish-yellow light. People more commonly call them glow worms due to their highly-efficient glowing ability. Lightning bugs are luminous flies with wings, but some female fireflies are wingless. Some surprisingly don't eat anything at all. Adult fireflies eat pollen, other lightning bugs, or nectar to survive. Their larvae feed on slugs, worms, and snails by injecting their chemicals into their prey. The larvae stay in the ground throughout winter and then pupate in spring. Female fireflies mostly lay eggs in damp places in the soil. The adult lightning bugs rest in the daytime and come out around dusk or midnight. These flying insects don't have hard forewings (elytra) like many beetles. In the U.S., fireflies are usually rare west of Kansas. They can be present in tropical as well as subtropical areas. North America hosts around 23 genera and 200 species of lightning bugs. Firefly is a common name used for these luminous insects. Lightning bugs are not actually bugs or flies, but they are beetles from the Lampyridae family. They generally don't bite humans, so these bugs are harmless. Lightning bugs are found primarily in moderate and tropical regions. These bugs are seen as a sign of romanticism. Wisconsin sees a massive light show of fireflies in June, July, and August. The Great Lakes area alone has about two dozen lightning bug species. These bugs have 2,000 about species worldwide, with more than 150 present in the United States. Lightning bugs, more commonly known as fireflies, are winged beetles that produce luminous effects.
