What are the characteristics of fireflies’ light?

The characteristics of firefly light are: the light is cold light, that is, there is light but no heat. The colors are mostly yellow and green.

Firefly (English: Firefly) is also known as luminous, sedum, radiant, night light, flowing firefly, night candle, dazzling night, etc. It belongs to the family Coleoptera and is a small beetle because its tail can emit fluorescence. , hence the name firefly. There are nearly 2,000 species of insects with luminous tails. The more common ones in my country include the black firefly, the red firefly, and the window-breasted firefly.

Fireflies undergo complete metamorphosis. They go through four stages in their life: egg, larvae and pupa. Aquatic fireflies usually complete one generation in four months, and there are two generations in one year. Terrestrial fireflies, on the other hand, only complete one generation in one year. The larvae need to molt six times from egg to pupa. The pupa period varies depending on the species, and the longest can reach more than 40 days. The life span of adults in the wild is generally 3-7 days, but some can last as long as 20-30 days.

The glow of fireflies is a type of bioluminescence. The light-emitting principle of fireflies is: fireflies have specialized luminescent cells. There are two types of chemical substances in the luminescent cells. One type is called luciferin (called firefly luciferin in fireflies), and the other type is called luciferin. called luciferase.

Luciferin can consume ATP under the catalysis of luciferase and react with oxygen. The reaction produces oxidized luciferin in the excited state. When oxidized luciferin returns to the ground state from the excited state, it releases photons. .
