<P> More than 900 species of crickets are described ; the Gryllidae are distributed all around the world except at latitudes 55 ° or higher , with the greatest diversity being in the tropics . They occur in varied habitats from grassland , bushes , and forests to marshes , beaches , and caves . Crickets are mainly nocturnal , and are best known for the loud , persistent , chirping song of males trying to attract females , although some species are mute . The singing species have good hearing , via the tympana ( eardrums ) on the tibiae of the front legs . </P>
