Why Do Fireflies Glow?

šŸ’” 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.
