Fig. 1. Phonotactic path of ten female M. elongata towards two speakers
broadcasting either synchronous chirps with a time delay of 140 ms of the
follower (A), chirps regularly alternating after 1 s (B), or chirps presented
in perfect synchrony with no time delay at all (C). Females prefer the leader
of two identical chirps (left speaker in A), and approach both alternating
signals and those in perfect synchrony with no preference.
