Field studies on the bushcricket Ephippiger ephippiger reveal that the males are highly mobile during their daily activity period. The distribution pattern of males is affected by the vegetation of the habitat. Males are clumped in areas with Sarothamnus scoparius (broom). The distribution implies the state of a fluid balance within the population. In the habitat the stridulatory period of males is influenced by climatic conditions. Singing is completely inhibited at a temperature below 17° C, during strong wind and rain. Thus, mating success and frequency is strongly affected by these biotic factors. Investigations in the laboratory show that constant ambient temperatures do not influence the daily stridulatory period; acoustically isolated females show a daily period of high locomotory activity nearly synchrone to the male stridulatory period.
对突灶螽（Ephippiger ephippiger）的野外研究表明，雄性突灶螽在其日常活动期间具有高度的移动性。雄性的分布模式受栖息地植被的影响。雄性聚集在有石南状棘豆（扫帚）的区域。这种分布意味着种群内部的流体平衡状态。在栖息地，雄性的鸣叫期受气候条件影响。在温度低于17摄氏度、强风和降雨期间，鸣叫完全受到抑制。因此，这些生物因素对交配成功率和频率有很大影响。实验室研究表明，恒定的环境温度不会影响每日鸣叫期；隔音环境中的雌性表现出几乎与雄性鸣叫期同步的每日高活动期。
