Male field cricket, Teleogryllus taiwanemma, is singing toward another cricket in the same case. The song seems to be the courtship song. The cricket who is loitering without emitting sound approaches the male who is singing the courtship song. Usually, cricket¡Çs mating behavior is performed after the female has ridden on the male back. The cricket who has been loitering tries to approach the singing male from the back of him, and tries to ride on his back. This is the beginning of action of a series seen in usual copulation. But, the cricket who was going to ride on the back is a male in fact. By emitting sound of the cricket on the back, the male who was singing courtship song has noticed it suddenly. He changed the courtship song into aggressive song, and dispersed the cricket.
