周期性蝉（Magicicada spp.）有性配对的形成发生在密集的聚集体中，并且涉及激烈的雄性与雄性对有限的交配机会的竞争。由于对性交流的了解有限，人们对这些物种的配对行为知之甚少。我们发现，具有性接受能力的雌性“魔蝉”会在听到雄性个体合唱时适时地用翅膀做出反应。这种以前未被识别的雌性反应在下文中被称为“拍翼”信号。我们记录了这种信号的性质、时间和物种特异性，以及它在未成熟和交配雌性中的缺失。我们还记录了雄性响应振翼信号的合唱和搜索行为的变化，以及雄性对信号视觉和听觉成分的反应。我们测试了这样的假设：女性感官心理学通过偏爱调频的男性叫声来塑造十进制叫声的进化，这些男性叫声在激烈的后轮合唱中更容易区分。在交配群体中，雄性魔蝉试图侵占正在进行的求爱，并通过在声音上掩盖潜在闯入者的叫声来参与干扰竞争，从而降低雌性做出反应的可能性。
Periodical cicada (Magicicada spp.) sexual pair formation takes place in dense aggregations and involves intense male-male competition for limited mating opportunities. Pair-forming behavior in these species has been poorly understood because of limited knowledge of sexual communication. We have found that sexually receptive female Magicicada Rick their wings in timed response to an individual chorusing male; this previously unrecognized female response is hereafter referred to as a 'wing-flick' signal. We document the nature, timing, and species-specificity of this signal as well as its absence in both immature and mated females. We also document changes in male chorusing and searching behavior in response to wing-flick signals and male responses to the signals' visual and acoustical components. We test the hypothesis that female sensory psychology has shaped the evolution of -decim calls by favoring frequency-modulated male calls that are more readily distinguishable in an intense back.-round chorus. Within mating aggregations, male Magicicada attempt to usurp ongoing courtships and also engage in interference competition by acoustically obscuring the calls of potential interlopers, reducing the likelihood of a female response.
