Tiger moths can foil attacks from bats by in effect crush the bats ' sonar , doing so by emitting sudden fit of ultrasound , scientists now detect . preceding research had revealed that many night - flee moths have evolve the ability to hearbat echo sounder . A number were even assure react with clicks of ultrasound . Other studies revealed that moth ultrasound could startle bats off . Research also show the outbursts could discourage bat that such moths had a nasty discernment , just as meretricious color on some animals can serve to guard off potential marauder . Still , there was the enticing hypothesis that some moths used sonography to actually cross bat echo sounder . To look for a case of sonar jamming , police detective engage ultrasonic recordings and high - speed infrared telecasting to analyse how self-aggrandising brown cricket bat ( Eptesicus fuscus ) interact with one particular species of ultrasound - utter Panthera tigris moth ( Bertholdia trigona ) over the trend of nine nights in enclosed elbow room . If the moth sounds were just meant to galvanise at-bat , chiropteran would finally get used to the outbursts and go on to catch the moth . If the insect clicks were just meant to warn bats they were unpalatable , the bat would have quit attack the moths after trying one first . However , the researcher view that bats neither increased nor diminish their odds of catching these moths , and instead their ability to get the moth remained consistently poor over time . This intimate the ultrasound bursts were not meant to startle the bats nor warn ofbad taste . As such , the insects might have evolved a genuine sonar - jamming defence mechanics to redeem them from bats . " This bring out that even a belittled moth can defeat the most sophisticated acoustical vulture known , " said researcher Aaron Corcoran , a biologist at Wake Forest University in Winston - Salem , N.C. " It ’s a terrific representative of an escalating arms race between predator and fair game , with each attempt to forever one - up the other . " Further depth psychology of the moth reveals it is well suited for disrupt sonar , have highly develop echography emitter . " These moths can make an unbelievable amount of strait , 450 mouse click in a tenth of a second , " Corcoran explained . " That ’s all-important , because a chiropteran ’s entire attack chronological succession can last just one second , maybe two second on the long terminal , and so the moths have to be speedy , listen to the bat echo sounding call and then figure out the good time to make the right sound to mob them . It ’s an inordinately loyal , dynamic response . " The researchers are now investigating how just about 20 species of chiropteran and 30 mintage of moths employ different attack and defense strategy in Arizona , using ultraviolet light to pull in the moth at Nox and high - hurrying cameras and microphones to memorialize their interactions . " Who are the winners and loser in these battles ? " Corcoran asked . " That ’s what we want to find out . " The scientists detailed their finding in the July 17 issue of the journalScience .
This tiger moth, Bertholdia trigona, is the first animal known to defend itself by jamming the sonar of its predator, bats.
