雄性Saitis Michaelseni Simon(蜘蛛目：跳蛛科)在求爱时发出声音，几米外都能听到。求爱的雄鸟在枯叶上发出刺耳的响声，位于叶子的另一边，与雌鸟相对。求爱展示包含视觉和听觉元素。求爱由三个阶段组成。在前两个阶段，雄性发声，在第三个阶段，它与雌性进行触觉接触，它交替发出阵阵响声和敲击声，在这两个阶段中，第一对腿撞击底层。突起明显是由于腹部前部短毛的加厚根部移过甲壳后部的两根绒毛造成的。这种发声机制以前还没有关于盐渍蜘蛛的报道。给出了由敲击和敲击产生的声音的频谱和调幅模式。
Male Saitis michaelseni Simon (Araneae: Salticidae) produce sounds during courtship which can be heard several metres away. Courting males stridulate on dead leaves and are positioned on the opposite side of the leaf from the female. The courtship display contains both visual and acoustic elements. Courtship consists of three phases. In the first two phases, the male stridulates, and in the third phase, in which he makes tactile contact with the female, he alternates bursts of stridulatory sound with bouts of percussive sound in which the first pair of legs strikes the substratum. Stridulation apparently results from the thickened bases of short hairs on the anterior part of the abdomen moving over two files on the posterior part of the carapace. This stridulatory mechanism has not been previously reported for salticid spiders. The frequency spectra and amplitude modulation patterns of sounds produced by stridulation and percussion are presented.
