研究了被拴系的、飞行的成年雌性海洋蟋蟀（Teleogryllus oceanicus）对声刺激的转向反应。蟋蟀对定向声音刺激的定向反应是将触角和后腿向一侧弯曲。这个回答是一种试图扭转。当刺激与同种呼叫歌曲的模型，从3-9 kHz的载波频率，蟋蟀转向声源。这表明一个积极的phonotactic响应飞行女性呼吁，同种男性。当提供一个选择之间的consepcific歌曲和歌曲的另一个物种，女性转向专门对同种歌曲，表明反应是物种特异性的。响应的方向取决于歌曲的载波频率，它表现出频率歧视。雌性转向呼叫歌曲时，它是在3-9千赫的载波频率播放，但从相同的歌曲模式从30-70千赫播放转身离开。这种对超声波刺激的负趋声性表明，蟋蟀和其他一些夜间飞行的昆虫一样，可以通过声音探测来躲避蝙蝠。
The steering responses of tethered, flying adult female crickets (Teleogryllus oceanicus) to acoustic stimulation were investigated. Crickets responded directionally to directional sound stimulation by bending their abdomens and hind legs to one side. This response was an attempt to turn. When stimulated with a model of conspecific calling song with a carrier frequency of from 3-9 kHz, crickets turned toward the sound source. This indicates a positive phonotactic response of flying females to calling, conspecific males. When offered a choice between consepcific song and the song of another species, females turned exclusively toward conspecific song, demonstrating that the response is species specific. The direction of the response is dependent on the carrier frequency of the song, and it demonstrates frequency discrimination. Females turned toward calling song when it was played at carrier frequencies from 3-9 kHz, but turned away from the same song pattern played at carrier frequencies from 30-70 kHz. This negative phonotaxis to ultrasonic stimuli suggests that crickets, like some other nocturnal flying insects, can evade bats by acoustic detection.
