The responses of Tettigonia cantans to species-specific song and substrate conducted vibration have been tested under three experimental regimes. When directional cues are adequate the sound source can be located by audition alone; where such cues fail to provide sufficient information then vibration signals become of value. In two-choice experiments vibrating substrates are preferred by both males and females moving towards the sound source. In multiple-choice experiments Tettigoniids may either detect and follow vibration gradients or the direction of the bending waves coming from the vibration source to orientate towards a conspecific.
已在三种实验条件下测试了纺织娘对物种特异性鸣声以及基质传导振动的反应。当定向线索充足时，声源仅通过听觉就能被定位；当这些线索无法提供足够信息时，振动信号就变得有价值了。在双选实验中，向声源移动的雄性和雌性纺织娘都更喜欢振动的基质。在多选实验中，纺织娘可能会检测并跟随振动梯度，或者来自振动源的弯曲波方向，以朝向同种个体定向。
