Most bio-sonar studies have focused on the reception of single target-echoes by echolocating bats. However, under natural conditions insect-targets often occur in swarms. Boonman et al. constructed life-like avatars of mosquitoes and placed them in constellations following natural statistics representing different densities and group sizes. Using a virtual acoustic paradigm they calculated the echoes received for 100 realizations of the swarm. To assess the contribution of insect-shape, they compared the responses to echoes of virtual clouds of point-targets. The authors found that, especially for dense clouds, modulating the emitted narrowband-signal by several kHz greatly enhances detection probability.
