Why Do Fireflies Glow?

💡 The Answer

• Fireflies produce light through a chemical reaction called bioluminescence in their lower abdomen.
• The reaction involves luciferin, luciferase, oxygen, and ATP, emitting light with nearly 100% efficiency.
• Each species has a unique flash pattern that helps males and females identify mates.
• Some fireflies use light to lure prey or warn predators of their bitter taste.
