The greater wax moth
This little guy has the hearing crown, with a hearing frequency of up to 300 kiloherz, it can hear 150 times more than us and can even hear 100 herz above a bat. Many species of moth have evolved ultrasound-sensitive ears owing to the predation pressure of echo-locating bats - this system is one of the best known examples of an evolutionary 'arms-race' between predator and prey."
