There are about 5,000 different kinds of ladybugs(瓢虫) in the world. They come in many different colours like blue, yellow, white, orange and black.
In many cultures, people think ladybugs can bring good luck. Most people like them because they are beautiful and not bad for people's health. But farmers love them because they eat plant-eating insects. One ladybug can eat up to 5,000 small insects in its lifetime!
Ladybugs are colourful for a reason. Their colours tell other animals, "Eat something else! I taste terrible."
Ladybugs are happy in many different habitats, such as forests, cities and along rivers. Ladybugs like to keep warm. When the weather turns cold, they look for a warm place to hibernate (冬眠), such as inside houses.
Here are some other facts about ladybugs:
● Though most ladybugs eat small insects, a few kinds eat plants.
● Ladybugs will clean themselves after a meal.
● There are more than 400 kinds of ladybugs in North America.
