Sexual selection and predation drive the repeated evolution of stridulation in Heteroptera and other arthropods

open access: yesBiological Reviews, Volume 98, Issue 3, Page 942-981, June 2023., 2023
ABSTRACT Acoustic and substrate‐borne vibrations are among the most widely used signalling modalities in animals.
