Leptophyes albovittata
The male calling song consists of single, short syllables presented at intervals of sev- eral seconds. The acoustic response behaviour of the female was first studied by Zhantiev and Korsunovskaya (1986, 1990, 2015). They showed that the female latency time is constant with reference to the beginning of the song. The females responded to song models independently of the duration of the model (tested from 10 ms up to 100 ms). Here we show that even very short signals (see L. punctatissima) are answered (Fig. 2C). It was therefore not surprising to see that calling songs of other species with the ap- propriate spectral properties were also answered (here Andreiniimon nuptialis; Fig. 2D). The female responses are produced during closing movements of the tegmina. However, during the re-opening of the tegmina soft impulses were sometimes observed (Fig. 2D). [1]
