Why Do Fireflies Light Up?

💡 The Answer

• Fireflies produce light through a chemical reaction called bioluminescence in their lower abdomen.
• This light is primarily used for communication, especially in attracting mates through flashing patterns.
• Different firefly species have unique flash patterns that help them identify their own kind.
• The light they produce is cold light, meaning nearly 100% of the energy is converted to light, not heat.
