The best known crickets are the house cricket of Europe and the common black, or field cricket of the United States. Tree crickets are white or pale green. The tree cricket lives in a tree and shrubs. They feed off of small insects called aphids.
Aphids are a pest that live on shrubs, plants and garden vegetables.
Birds, cats, frogs, toads and other animals eat the cricket. Crickets are known for their songs. Each kind of cricket has a different song. Their songs help male and female crickets find each other in order to reproduce. Crickets produce sound by rubbing their two front wings together.
