The ubiquitous greater wax moth is ordinary in every fashion but one : It has the power to discover the highest - known sound frequency .
The greater wax moth ’s hearing goes up to about 300 kilohertz , intimately 100 kHz higher than the hearing of some bat .
The greater wax moth can hear the highest-known sound frequency.
" This is the creature with the highest frequency predisposition yet register , there ’s no other animal that can hear such a gamey frequency , " said study co - generator James Windmill , a bioacoustician at the University of Strathclyde in Scotland .
The moth’sultrasonichearing range of a function , which was line Tuesday ( May 7 ) in the daybook Biology Letters , could help the creature hear the sonar communicating of their piranha , bats , Windmill say . [ Flying Mammals : Gallery of Amazing Bats ]
Humble moth
The characterless brownmoth species , Galleria mellonella , populate in North America , Europe and Asia and has a 1.1 inch ( 3 centimeter ) wingspan . Its tiny ear is just 0.02 inches ( 0.5 millimeters ) across .
Other researchers had screen the hearing of the greater wax moth , but gift up at about 100 kHz . But the moth ’s pinna was so sensitive at that frequency that Windmill and his colleagues wondered just how high-pitched they could get wind . ( By comparing , the human ear can listen sounds up to just 20 kHz )
The research team used a laser vibrometer to measure the quiver of the ear in response to intelligent waves . They also appraise electric signals in the ear boldness .
They then watched the spike as they prove the sound absolute frequency eminent and higher .
The researchers plant that the moth ’s hearing go to an stupefying 300 kHtz .
Bat versus moth
The squad hypothesizes that the moth ’s ultrasonic hearing could avail it evade their predators in many environment .
The moth " would probably be the food for thought for many different bat using many different frequency , " Windmill told LiveScience .
Bat echo sounding callscan go as high as 212 kHz , so the eminent - oftenness auditory sense could help the greater wax moth hear a different piranha coinage ' claim and evade them , Windmill said .
The other possibility is that their ears help females get a line the mating calls of Male .
Though male sexual union calls are at a lower pitch ( about 80 kHz ) , they are fantastically short pulses . Because of how hearing works , an ear tuned to the lower delivery of the union calls would still be moving in reply to one pulse when the 2nd was made . Being tune up to a higher frequency ambit could allow the female to separate the private pulses , Windmill say .
