FIGURE 2 in Taxonomic, bioacoustic and faunistic data on a collection of Tettigonioidea from Eastern Congo (Insecta: Orthoptera)

FIGURE 2. Oscillograms of stridulatory movements and song [synchronous registration of left tegmen movement (upward deflection represents opening, downward closing) and sound; 15 s sequence]. In the first half of the recording of H. leggei, the stridulatory movement is superimposed by a slight body movement, mimicking a continously increasing opening of the tegmina.

FIGURE 4. Frequency spectra of calling songs. In Horatosphaga leggei, the black line respresents the evaluation of a 50 ms part of the song during the production of microsyllables A, the solid part that of a 50 ms part during the production of macrosyllables (same scale).
