The Japanese lacertid lizard Takydromus tachydromoides and the praying mantis Tenodera aridifolia are sympatric generalist predators feeding on similar prey. To confirm reciprocal predation between them, we observed the behavioural interactions between the lizards and the mantises of different sizes in a laboratory condition. The lizards caught small mantises (from first to fifth instars), but sometimes escaped from large mantises (from sixth instar to adult). Large mantises occasionally showed catch responses to the lizards. The lizards sometimes caught the mantis without a tongue-flick response (sampling of chemical cues), and they sometimes did not catch the small mantises showing immobile or cryptic responses that prevent visual detection. These results suggested the primary role of vision on recognition of the mantis as a prey. The lizards spent a longer time to approach larger mantises. The time from orienting to catch was longer when the lizards showed tongue-flick responses. The lizard also spent a longer time before deciding to escape from the mantis than to catch it. Biological significance of these differences in timing was discussed.

蜥蜴 Takydromus tachydromoides 和螳螂 Tenodera aridifolia 之间的行为相互作用表明它们之间存在相互捕食
日本蜘蛛蜥蜴 Takydromus tachydromoides 和螳螂 Tenodera aridifolia 是同域通才掠食者,以类似的猎物为食。为了证实它们之间的相互捕食,我们在实验室条件下观察了蜥蜴和不同大小的螳螂之间的行为相互作用。蜥蜴捕捉小螳螂(从一龄到五龄),但有时会从大型螳螂(从六龄到成年)逃脱。大型螳螂偶尔会表现出对蜥蜴的捕捉反应。蜥蜴有时在没有甩舌反应(化学线索采样)的情况下捕捉到螳螂,有时它们也没有捕捉到表现出无法移动或隐蔽反应的小型螳螂,这些反应阻止了视觉检测。这些结果表明视觉在识别螳螂为猎物方面的主要作用。蜥蜴花了更长的时间来接近更大的螳螂。当蜥蜴表现出弹舌反应时,从定向到捕获的时间更长。蜥蜴也花了更长的时间才决定逃离螳螂而不是抓住它。讨论了这些时间差异的生物学意义。
