Sexual pair-formation in a cicada mediated by acoustic behaviour of females and positive phonotaxis of males

Abstract The functions of female song found in a few cicadas have rarely been studied. In the cicada Subpsaltria yangi we investigated the acoustic behaviour and signal structure of songs produced by females, the phonotaxis of males, and mate choice, as well as the selective pressure imposed on this...
