“…For males, signalling and flying were equally risky but walking was safe. Flight is a rare event for both sexes [31]. Within trees, males mainly walk following the substrate vibration once they receive female reply signals [19,32], decreasing their risk of bat predation by minimizing the time spent in high-risk acoustic signalling.…”

Duetting is a behaviour observed in some animal species, in which both males and females participate in signalling to find mates. It may have evolved as an adaptation to reduce the costs associated with mate-finding behaviours, such as predation risk. Duetting systems allow estimation of sex-specific predation risks of signalling and searching in the same species, giving insights into the selective forces acting on these behaviours. Using an acoustic–vibratory duetting katydid, Onomarchus uninotatus , and its bat predator, Megaderma spasma , we estimated the sex-specific predation costs of different mate-finding behaviours, such as walking, flying and signalling, by conducting experiments with untethered live katydids and bats. We found that acoustic–vibratory duetting benefits both the sexes as a low-risk mate-finding strategy.
