Advertisement songs play an important role on species recognition and mate choice in cicadas. Males generate complex species-specific calling songs to attract conspecific females. In central Korea, Cryptotympana atrata, Meimuna mongolica and Hyalessa fuscata are widely distributed, yet their songs have not been described. We analyzed acoustic characteristics of these cicadas’ advertisement songs in temporal and spectral domains. In sum, C. atrata’s songs followed the pulse-echeme pattern, in which each echeme consisted of groups of pulses with the peak frequency of 6423 ± 589 Hz. In M. mongolica, the calling song had the pulse-echeme-combined echeme-phrase structure. A group of three echemes formed one combined echeme, and one full phrase comprised hundreds of combined echemes. Lastly, the calling song of H. fuscata was constructed of the pulseecheme- phrase structure, in which one full phrase included a train of low and high-frequency echemes and the ending echeme at the end of the phrase. The carrier frequency of low frequency echeme was 4576 ± 151 Hz and that of high frequency one was 14089 ± 628 Hz.
