FIGURE 5. Hyalessa maculaticollis (De Motschulsky, 1866). Calling song. A, Power frequency spectrum represented with overlay of 176 spectra computed in the middle of the signal showing dominant frequencies marked by F1, F2 and F3, spectrogram and oscillogram (from top to bottom) of a sequence with the three parts of the calling song. B, Detailed oscillogram of the end of A showing two phrases. C, Detailed spectrogram and oscillogram of a part of B showing three of the two different echeme types with their amplitude variation.
