Night-Lights

Sorry, no night light facts but here is a similiar night light...Lightning bugs or Fireflies!
Why do these creatures glow? The summer evening light shows that you see are performed by male fireflies. They flash patterns of light to females. The females signal in response from perches in or near the ground. When the male sees the female’s flash he continues to signal and moves closer. Eventually, through a series of flashes, they find each other and mate. Each species of firefly sends different mating signals. The light given off by fireflies during their abdominal flashes is called bioluminescence. It happens when oxygen and the organic compound luciferin react together in the presence of the enzyme, lucifereace. This creates light!
