Ormia ochracea: Female parasitoid flies acoustically stalk and lay their larvae on and around the signalling cricket. The larvae burrow inside the cricket. A week later the larval fly burrows out of the host, killing the cricket. Acoustic signalling is, therefore, beneficial as it enhances mating success, and yet costly as it increases the chances of dying young.
