Among grasshoppers the Saltatoria emit "complex and highly specific songs." The hind legs
are rubbed against
the wings and the sounds produced are perceived by tympanal organs on the legs. Such
activity is a clear mating
display. Above a certain temperature the males of the species may sing spontaneously,
sounding a number of
notes followed by a pause. A receptive female answers with a softer call. The male and female
then call
alternately, the male now with a newly modified song. In threat displays two males may sing at
each other.
Perdeck has shown ("The Isolating Value of Specific Song Patterns in Two Sibling Species of
Grasshoppers -
Chorthippus brunneus Thumb and C. biggutulus L." "Behaviour", Vol. 12, pp.
1-75) that grasshopper songs are
sexually stimulating to both sexes. In fact females get so excited that they even try to mate
with silent males of
the wrong species; and males speed up their locomotion and their efforts to copulate.
