Do you know why fireflies glow in the dark of night? How to make your own light..

After the summer evenings, when the darkness of night starts setting in, small fireflies are seen twinkling in the fields, gardens, or on the banks of rivers. This sight looks very magical, as if stars have scattered on the earth. But have you ever wondered why these small insects glow only at night?

How do fireflies produce light inside themselves, due to which they appear to twinkle? Actually, nature and science are behind this. Let us know the reason behind this.

How do fireflies glow?

This phenomenon of fireflies glowing is called "Bioluminescence" in the language of science. It means producing light through a chemical process in a living creature. There is a special organ in the lower part of the firefly's stomach. Two important chemicals are found in this organ: luciferin and luciferase.

When the firefly breathes, oxygen mixes with these chemicals, and a chemical reaction occurs. This reaction releases energy, which appears in the form of light. Surprisingly, very little heat is produced in this process, so it is also called "cold light".

Why do fireflies glow?

Now the question arises, why is this light visible only at night? The most important goal of the firefly's life is hidden behind this - reproduction and communication.

Attracting a partner - The darkness of night is like a perfect stage for fireflies. Different species of fireflies have their own glow. Male fireflies fly and send light signals in this rhythm. Female fireflies sitting far away recognize this 'code' and respond in the same pattern. In this way, they find each other even in the dark. Their light is not visible in daylight, so this entire process is possible only at night.

Self-defense- This glow of fireflies also serves the purpose of protection. This glowing signal is a warning to predators. Fireflies have certain chemicals in their body that make them poisonous or tasteless. Predators, such as birds or frogs, stay away from them after seeing this glow.
