Moth Mimicry: Using Ultrasound to Avoid Bats
This video follows scientists as they uncover the ways in which moth species in Gorongosa National Park use ultrasound to avoid being eaten by bats.
Biologist Jesse Barber of Boise State University was joined by two graduate students in Gorongosa National Park to study bat-moth, predator-prey interactions. They designed several experiments to determine the strategies used by Gorongosa moths to avoid being eaten by bats. Some moths use ultrasound to either jam bats’ sonars or to signal to bats that they taste bad. Barber explains that some of these species are Batesian mimics, because they don’t truly taste bad but mimic the ultrasound of other moths that do, tricking the bats into avoiding them as food.
