Prey vibrations on webs of Latrodectus hesperus and Tegenaria agrestis . Oscillograms depicting velocity [mm/s] over time [s] (upper panels) and frequency [Hz] (lower panels) of cricket and house fly vibrations recorded on empty webs of Latrodectus hesperus and Tegenaria agrestis. “a.e.” refers to root mean square amplitude envelope of the vibration and “a.m.f” refers to amplitude modulation factor measured between the lowest and the highest point of the amplitude envelope (in this example, a.m.f. = 120).
