Chalk fluorescents are the ancestors of fireflies, how is their purpose of emitting light different

Fireflies glow for the purpose of courtship, whereas chalk fluorites emit light to scare creatures that want to attack them for the purpose of protecting themselves.

As the most primitive fireflies 100 million years ago, they glow to defend themselves against predator attacks and self-protection, unlike today's fireflies that glow for courtship.

Also daylight insects, they glow in order to defend themselves against predators. The purpose of fireflies to glow is for courtship and reproduction of offspring.

Chalk fluorescent insects are the ancestors of fireflies, and the purpose of their glow is to frighten the creatures that approach them and achieve the purpose of protecting themselves, because they live in an extremely harsh environment and have many large carnivores, but these carnivores instinctively have a fear of light, and they will not want to get close when they see them glowing. And fireflies glow to attract the attention of the opposite sex, mainly to reproduce.

Fireflies rely on phosphorus-containing luminescent matter and luminescent enzymes in light-emitting cells to emit light, and phosphorus-containing luminescent matter and luminescent enzymes produce a chemical reaction, which has a very high luminescence efficiency of up to 95%.

There is a luminescent device at the end of the firefly's abdomen, which is filled with phosphorus-containing luminescent matter and luminescent enzymes, and when the firefly breathes, the fluorescein is oxidized and synthesized luciferase by inhalation, and the firefly emits light. Fireflies have a very high luminescence efficiency, which can convert almost all chemical energy into visible light, and it is a cold light with almost no thermal radiation and no magnetic field.

The purpose of fireflies to glowThe bright light emitted by fireflies is not only for lighting, but mainly for signaling, and the signal emitted by each purpose is different. Different species of fireflies emit different frequencies, brightness, ways and colors of light, and most of the fireflies we usually come into contact with are yellow-yellow or green-green glowing. It can be said that this is the language of fireflies, just like the sos** of humans, such as courtship, vigilance, trapping, and communication with their own kind, all of which are communicated in this way.

1.Firefly.

It is characterized by a relatively small, semi-spherical shape of the head, and it also emits light.

2.Fireflies are carnivorous and often prey on snails and slugs.

and other mollusks and earthworms.

After obtaining the prey, the secretion is injected into the prey with the upper jaw, digested in vitro, and then inhaled into the body.

3.Fireflies are divided into two categories, terrestrial and aquatic, according to their living environment, with the former accounting for the majority.

4.Terrestrial firefly larvae mostly inhabit places with high shading, lush herbaceous vegetation and high relative humidity, and each insect state of aquatic fireflies has different ecological habitats.

5.The pupal stage is spent next to the water.

Fireflies rely on chemical reactions in light-emitting cells to emit light, and this reaction has a very high luminescence efficiency of up to 95%. In other words, almost all of the energy released in the reaction is converted into light energy, and only a very small part is released in the form of heat energy.

Therefore, the temperature of fireflies is very low, and it is a natural and efficient cold light source. In stark contrast, only about 10% of the energy of incandescent lamps used by humans is converted into light, and the remaining energy is wasted as heat, as are other halogen tungsten lamps and arc lamps.

Firefly luminescence principle

In nature, many plants and animals have the ability to emit light, and this phenomenon of biological luminescence is also known as "bioluminescence". Bioluminescence is mainly divided into two types, one is that the organism itself has a luminescent device and can control the luminescence independently, and the other is that the organism does not have a specialized luminaire and needs to live in symbiosis with luminescent bacteria or be parasitic and emit light, and does not have the ability to control.

Except for some diurnal species of fireflies that cannot emit light, most firefly eggs, larvae, pupae and adults can emit dazzling light. Due to the different growth stages of fireflies, the location of the luminaires is also different, the luminaires of the larvae are located on both sides of the 8th segment of the abdomen, and the luminaires of the pupal are very similar to those of the adults, both at the end of the abdomen 1 2 segments.

The reason why fireflies emit light is because it has a protein that is fluorescent. This thing loses ().
