声学行为的进化和调节其产生的形态特征的进化往往是耦合的。信号特征的基本形态缺乏变异有可能限制信号的进化。这种关系在田野蟋蟀中尤其可能，雄性蟋蟀通过前翼上的特殊结构发出声学广告信号来吸引雌性蟋蟀。在这项研究中，我们描述了来自六个已知具有不同广告叫声的异地黑野蟋蟀种群的雄性前翼的大小和几何形状。我们使用野生捕获的和普通花园饲养的队列从这些种群中抽取样本，使我们能够测试翅膀形态和叫声结构之间的多变量关系。我们表明，形状的异速生长在不同种群之间存在差异。然而，令人惊讶的是，在种群内，翅膀形状和叫声结构之间存在少量的协变。考虑到雄性体型对蟋蟀性别选择的重要性，我们观察到的种群间的差异可能会影响该物种的广告叫声的进化。
The evolution of acoustic behaviour and that of the morphological traits mediating its production are often coupled. Lack of variation in the underlying morphology of signalling traits has the potential to constrain signal evolution. This relationship is particularly likely in field crickets, where males produce acoustic advertisement signals to attract females by stridulating with specialized structures on their forewings. In this study, we characterise the size and geometric shape of the forewings of males from six allopatric populations of the black field cricket (Teleogryllus commodus) known to have divergent advertisement calls. We sample from each of these populations using both wild-caught and common-garden reared cohorts, allowing us to test for multivariate relationships between wing morphology and call structure. We show that the allometry of shape has diverged across populations. However, there was a surprisingly small amount of covariation between wing shape and call structure within populations. Given the importance of male size for sexual selection in crickets, the divergence we observe among populations has the potential to influence the evolution of advertisement calls in this species.
