From: A meal or a male: the ‘whispers’ of black widow males do not trigger a predatory response in females
Response of female Latrodectus hesperus to playback of high- and low-amplitude prey and male vibrations. (a) Proportion of Latrodectus hesperus females responding aggressively to vibrations produced by house fly prey or conspecific males played back at high or low amplitude at a distance of 15 cm (n = 16 for each treatment). Whiskers = standard error; (b) Time [s] elapsed before females initiated a predatory response (number of responding females: n = 5 for prey/low, n = 7 for male/low, n = 14 for both prey/high and male/high).
