One of the more unusual notions about stridulation arose in 1995 when Flavio Roces and Bert Holldobler of the University of Wurzburg in Germany reported that leaf-cutting ants tend to stridulate as they slice off snippets of tender leaves.
However, offering ants both prime leaves and chemically tainted ones revealed that workers stridulate more on desirable than less-favored leaves, regardless of any differences in the toughness of the cutting task.
gorgonensis, this chirp pattern does not occur, males
stridulate continuously for several minutes, and the frequency of the calls is nearly 23 kHz (see bioacoustics section, Figs 2-4).
During sunny conditions, almost every male
stridulates, which makes it possible to get reliable estimates of adult population size just by walking through a patch in straight lines spaced at 4 m and counting each male.

7), the male obviously
stridulates first with the few large teeth at the distal part of the file and uses the long dense part of the file only during the second half of the song.

stridulates defensively, the Triatominae (Reduviidae) (Schilman et al.
