Com app and favorite K. an extensive and news radio choose a program from our archives when a tiger moth in the vicinity it produces this scientists think that it may be a kind of insect battlecry to help ward off the predator this is the pulse of the planet this high frequency calls can slow down thirty times so that we can hear it one zero two lines of defenses the first is that they have wonderful years they can hear the bats come is a professor of biology at Wake Forest University in North Carolina they go through a series of evasive maneuvers loops spirals and power dives designed to evade the back but some models do more than just the V. bats some modest talk back to bats they produce high frequency clicks in response to the echo location cries of bands and there are two theories about what these high frequency clicks are for one is that they are jamming vehicle location sonar in this case the class would be perceived as multiple echoes which we back multiple acoustic images you will be able to tell which one is in fact the month so with their way the sound might also be a message to the cats doing well to find dinner elsewhere tiger moths feed on toxic plants which gives them an unpleasant taste this works the same way that the bright coloration works in these markets and they can produce the high frequency sounds the bats can hear them and then learned that these insects are in fact poisonous.
