Foraging diurnal lizards are well known for their use of visual and chemical cues to detect prey. We already showed that the Balearic lizard is able to detect prey using visual and chemical cues, even from airborne odors. In this study we carried out a field experiment to test if lizards can detect prey using acoustic cues. Our results show that Podarcis lilfordi is able to detect flies trapped inside opaque cups, only using acoustic cues. To our knowledge, this is the first known case of phonotaxis of a diurnal lizard. Thus, P. lilfordi can detect, from far away, current pollinators trapped inside floral chambers of the dead horse arum, Helicodiceros muscivorus. This is another behavioral trait displayed by the Balearic lizard during its complex interaction with the dead horse arum.

听起来像食物：昼行蜥蜴的趋声性

昼夜觅食的蜥蜴因其使用视觉和化学线索来检测猎物而闻名。我们已经证明巴利阿里蜥蜴能够使用视觉和化学线索来探测猎物，甚至可以通过空气中的气味来探测。在这项研究中，我们进行了一项实地实验，以测试蜥蜴是否可以使用声学线索检测猎物。我们的结果表明，Podarcis lilfordi 仅使用声学线索就能够检测到困在不透明杯子内的苍蝇。据我们所知，这是已知的第一个昼夜蜥蜴趋向性的案例。因此，P. lilfordi 可以从很远的地方检测到被困在死马 arum Helicodiceros muscivorus 花室中的当前传粉者。这是巴利阿里蜥蜴在与死马阿鲁姆的复杂互动过程中表现出的另一种行为特征。
