Daddy longlegs prey on small insects.
They also eat dead insects and fallen fruit. When disturbed, many species of daddy longlegs can give off a bad odor, but they do not bite. In the tropics, some species gather in great enough numbers to cover a small bush. If disturbed, all the daddy longlegs will shake violently, causing the entire bush to move. In England, the crane fly is called daddy longlegs.
