Obs: Observation type (caged cicadas and katydids, playback of cicada song to caged katydids, or field observations). # Echemes: Number of song echemes in recording. # Cues: Number of echemes that cue female replies. # Replies: Number of katydid clicks in recording. # Correct: Number of katydid replies that follow a song cue. Tallies are not available for five anecdotal field observations; however in all cases except K. umbrimargo, for which only a brief interaction was observed, many katydid clicks followed song cues. * indicates cicada songs included in Figs. 5– 7. Temporary field nicknames for undescribed taxa are indicated by quotation marks. P-value shows a binomial test of association of katydid replies with cicada song cues (see Methods).
