"Most cricket species are musical, sound-producing insects that have long been part of human life and lore. For instance, according to Polynesian creed, crickets are embodiments of the souls of loved ones, and in many countries a cricket singing at the hearth is thought to bring luck and protect the home against evil spirits. The fierce rivalry behavior of male crickets was well known in ancient China; games were organized and bets were waged on the outcome of their battles. But it is the elaborate behavior of crickets, and especially their acoustic communication, which has always drawn the most attention from biologists and the general public."
