... of their effectiveness as a defence against echolocating bats. Neuroptera Insect hearing Bioacoustics Bat echolocation Desert The ability to hear airborne sound has evolved independently at least 18–20 times (see Yager, 1999 ; Yack, 2004 ; Strauß and Lakes-Harlan, 2014 ) across seven insect orders...

.... Published by The Company of Biologists Ltd 2016 Summary: Field recordings of Eptesicus fuscus reveal highly intense source levels and stereotypic flight behaviour, potentially as a strategy to optimize foraging efficiency by minimizing sensory processing load. Bat echolocation Source level...

... composition of calls. We examined the effects of broadband-filtered noise on the spectro-temporal composition of horseshoe bat echolocation calls, which consist of a constant-frequency component and initial and terminal frequency-modulated components. We found that the frequency-modulated components became...

... broadcasts are brief, ultrasonic frequency-modulated (FM) chirps consisting of several harmonic frequency sweeps that collectively cover frequencies from about 20 to 100 kHz. The operating range of the big brown bat's echolocation system is limited, by spherical spreading and atmospheric attenuation...

... is assumed to arise from its ability to listen for the bats' echolocation calls and take evasive action; however, the auditory characteristics of this moth or any tropically distributed Australian moth have never been examined. We investigated the ears of S. spectans and determined that they are among...

... produced by attacking versus searching bats, suggesting that it either recognizes some acoustic feature of this phase of the bat's echolocation calls or that it simply reacts to their increased power as the bat closes. Here, we used a habituation/generalization paradigm to demonstrate that C. tenera...
