在裸翅目丛林蟋蟀Ancistrura nigrovittata中寻找配偶是通过二重唱来实现的，雌性蟋蟀用简短的声音回应雄性的歌声。在人造歌曲模型的实验中，我们分析了引发女性反应所需的参数。男歌的一节由一组5-9个音节组成，在大约400毫秒的间隔后，紧随其后的是最后一个音节。女性的反应依赖于两个过程：(I)识别音节组属于同一特定的男性；(Ii)感知最后一个音节作为触发。识别过程的关键参数是音节和音节停顿的持续时间，以及组中的音节数量。然而，即使有最优的音节组，响应概率仍然取决于音节组和最后一个音节之间的间隔。只有当男性歌曲的最后一个音节在250毫秒长的时间窗口内出现时，女性才会做出反应，该时间窗口从男性音节组结束后大约250毫秒开始。她的回答只有一个滴答声，紧跟在雄性的最后一个音节后面，等待时间只有25ms。
Mate finding in the phaneropterid bushcricket Ancistrura nigrovittata is achieved by a duet, where the female replies with a short sound to the male song. In experiments with artificial song models we analysed the parameters necessary for eliciting a female response. A verse of the male song consists of a group of 5-9 syllables which after an interval of about 400 ms is followed by a final syllable. The female response was shown to depend on two processes: (i) recognition of the syllable group as belonging to a conspecific male and (ii) perception of the final syllable as a trigger. Critical parameters for the recognition process are the duration of syllables and syllable pauses, as well as the number of syllables in a group. However, even with an optimal syllable group, the response probability still depends on the interval between the syllable group and the final syllable. The female only responds when the final syllable of the male song occurs within a 250 ms long time window beginning approximately 250 ms after the end of the male's syllable group. Her reply consists of a single tick, which follows the male's final syllable with a latency of only 25 ms.
