  • Title: Thermal dependence of trap building in predatory antlion larvae (Neuroptera: Myrmeleontidae).
    Author: Antoł A, Rojek W, Miler K, Czarnoleski M.
    Journal: J Ethol; 2018; 36(2):199-203. PubMed ID: 29725155.
    Abstract:
    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.
