Question

  There are about 5，000 different kinds of lady-bugs in the world. They come in many different colours. Their bright colours warn other animals and insects not to eat them. Ladybugs taste bad. A bird or a frog that eats a ladybug will remember the bright colours and it will not eat another ladybug with the same colours again. When ladybugs are in danger,they will give out a fluid(液体) that tastes terrible.

In many cultures,the ladybug is considered to be a symbol of good luck. Most ladybugs are kind to humans. They eat other insects which destroy crops. One ladybug can eat up to 5,000 insects in its lifetime.

Ladybugs have six short legs. They live in many different places， including green lands,forests，cities，the countryside and along rivers. Different ladybugs have different spots (点) . Some of them don’t have spots at all. The most common kind in North America is the 7-spotted ladybug. The 7-spotted ladybugs are the most active from spring to autumn. When the weather turns cold，they look for a warm place to sleep,such as under stones or in houses.
