Insects have evolved a diversity of hearing organs specialized to detect sounds critical for survival. We report on a unique structure on butterfly wings that enhances hearing. The Satyrini are a diverse group of butterflies occurring throughout the world. One of their distinguishing features is a conspicuous swelling of their forewing vein, but the functional significance of this structure is unknown. Here, we show that wing vein inflations function in hearing. Using the common wood nymph, , as a model, we show that (i) these butterflies have ears on their forewings that are most sensitive to low frequency sounds (less than 5 kHz); (ii) inflated wing veins are directly connected to the ears; and (iii) when vein inflations are ablated, sensitivity to low frequency sounds is impaired. We propose that inflated veins contribute to low frequency hearing by impedance matching.
昆虫进化出了多种多样的听觉器官，专门用于探测对生存至关重要的声音。我们报告了蝴蝶翅膀上一种增强听力的独特结构。眼蝶科是一个分布于世界各地的多样化蝴蝶群体。它们的一个显著特征是前翅翅脉明显膨胀，但该结构的功能意义尚不清楚。在这里，我们展示了翅膀脉膨胀在听觉中的作用。我们以常见的木樨蝉为模型，发现（i）这些蝴蝶的前翅上有耳朵，对低频声音（小于 5 kHz）最敏感；（ii）膨胀的翅脉直接与耳朵相连；（iii）当翅脉膨胀被切除时，对低频声音的敏感性受损。我们提出，膨胀的翅脉通过阻抗匹配有助于低频听力。
