Trap-building predators remain under strong selection from thermal microenvironments. To address how soil temperature and body size affect trap building, we conducted a laboratory experiment using larvae of the antlion Myrmeleon bore at six ecologically relevant temperatures. Larger larvae built larger traps, and warmer soil led to more and larger traps. Body mass did not alter the dependence of trap building on temperature. Our results suggest that the physiological capacity of antlion larvae, which is affected by larval size and body temperature, is the major determinant of trap building. This effect should be considered when assessing interactions between antlions and prey.

捕食性蚁狮幼虫中陷阱构建的热依赖性（神经翅目：Myrmeleontidae）

陷阱建造捕食者仍然受到热微环境的强烈选择。为了解决土壤温度和体型如何影响陷阱构建，我们在六个生态相关温度下使用蚁狮 Myrmeleon 钻孔的幼虫进行了一项实验室实验。较大的幼虫建立更大的陷阱，温暖的土壤导致更多更大的陷阱。体重并没有改变陷阱建造对温度的依赖性。我们的研究结果表明，蚁狮幼虫的生理能力受幼虫大小和体温的影响，是陷阱构建的主要决定因素。在评估蚁狮和猎物之间的相互作用时，应考虑这种影响。
