  Cicadas (Homoptera:Cicadidae) are insects able to produce loudly songs and it
is known that the mechanism to produce sound of tymballing cicadas works as a
Helmholtz resonator. In this work we offer evidence on the participation of the
wings in a high quality resonating process which defines the details of the
acoustic properties of the calling song. The study is carry on \textit{Quesada
gigas} species and it is dividied in three stages: (i) the acoustical
characterization of the abdominal cavity, (ii) the record and calculation of
frequency spectrum of the calling song, and (iii) the measurement of the
vibration modes of the wings. The comparison between all the results
unequivocally show the dramatic influence of the wings in the moment in which
the insect emits its calling song.
