As the calling males are nut informed aboul either variable. they can maintain only acoustic rather than absolute distances to their neighbours. Males in which the sound output is experimentally reduced. or which live within denser vegetation. move closer together than the controls (Dadour & Bailey, 1990). But, there is yet another and even more severe problem, namely to localize rather than only to detect the sound source. Due 10 multiple renection and scattering of sound in vegetation, the sound field around a listening insect might become ralher diffuse (Fig.

Some details 01 sonar systems should be dillerem in aquatic and terrestrial animals. For example. sounds of constant Irequency exhibit higher velocities and larger wavelengths in water than in air. Hence. the same accuracy 01 orientation (for data on toothed whales see Au. 1988; Wiirsig. t 989) requires that the echolocative sounds are 01 higher frequencies in aquatic than in terrestrial animals. This is indeed what occurs (Nachtigall & Moore. 1988). ~ :I: 2 M 0 17 24 26 35 H ,, 50 55 Best frequency (kHz) Fig.
