A recent publication describes how certain moths have evolved highly efficient acoustic camouflage in their arms race against echo-locating bats - see T R Neil et al., Proc. Natl. Acad. Sci. USA, 2020, 117, 31134 (link below). The discovery may have useful practical applications: the paper describes how the resulting ultra-thin sound-absorbing materials provide "enticing ways to design high-performance noise mitigation devices".
