Jul 29, 2019 · Fireflies produce light in special organs in their abdomens by combining a chemical called luciferin, enzymes called luciferases, oxygen and the fuel for cellular work, ATP. Entomologists...
Sep 5, 2005 · Fireflies appear to light up for a variety of reasons. The larvae produce short glows and are primarily active at night, even though many species are subterranean or semi-aquatic.

Fireflies produce light in special organs in their abdomens by combining a chemical called luciferin, enzymes called luciferases, oxygen and the fuel for cellular work, ATP. Entomologists think they control their flashing by regulating how much oxygen goes to their light-producing organs. Fireflies probably originally evolved the ability to light u...
Many fireflies protect themselves from predators with chemicals called lucibufagins. These are molecules the insects synthesize from other chemicals they eat in their diet. Lucibufagins are chemically very similar to the toxins toads exude on their skins, and while they are toxic in the right doses, they are also extremely distasteful. Birds and ot...
Most fireflies are habitat specialists, using woodlands, meadows and marshes. They rely on that habitat remaining undisturbed for the year or more it takes them to complete their lifecycles. These insects spend most of their lives as larvaepreying on earthworms and other animals in the soil or leaf litter – most adults don’t feed at all. If that ha...
Jul 7, 2021 · But when the swarm reaches a certain density, the fireflies begin to blink in unison. “Above that threshold, it is almost perfect synchronization,” with rhythmic, coordinated waves of light ...

Jun 8, 2022 · The light of a firefly is a chemical reaction caused by an organic compound – luciferin – in their abdomens. As air rushes into a firefly’s abdomen, it reacts with the luciferin.
