Answer:

The conspicuous colors of ladybugs contrast sharply with the green foliage they inhabit, and they're hard to overlook. These little round beetles are mostly predators, eating aphids and other harmful insects. The U.S. contains over 500 species of ladybugs, and there are over 4,500 kinds worldwide. They're used as biological control agents, and some species have been introduced from other countries for this purpose.
