Passage 1 The Secret of Fireflies
Fireflies are not flies—they are beetles. They can make light in their bodies. This light is cold and does not burn. Fireflies use the light to talk to each other. Male fireflies fly and flash light to find mates. Female fireflies on the ground flash back if they like the message.
Most fireflies live in warm and wet places, like forests and riversides. Their light is one of the most amazing sights in nature. At night, thousands of fireflies look like little stars falling to the ground.
Some people think fireflies’ light is magic, but it is a kind of chemical light called bioluminescence. Now many fireflies are in danger because of light pollution and habitat loss. We need to protect these wonderful natural lights.
