Moth Mimicry: Using Ultrasound to Avoid Bats | HHMI BioInteractive Video

- 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.
Jesse Barber of Boise State University headed to Gorongosa National Park with two graduate students to study bat-moth, predator-prey interactions. They design several experiments to determine the strategies that have evolved in these Gorongosa moths to avoid being eaten by bats. The strategies involve the use of ultrasound to either jam bats’ sonars or to signal to bats that they taste bad. Some of the moth species are Batesian mimics in that they don’t truly taste bad but mimic the ultrasound of moths that do.

Utterly fascinating, and damn near incredible in the literal sense of the word. I was just reading about Jesse and his studies in the book An Immense World by Ed Yong (I HIGHLY recommend it). Mimicry is so interesting to me to begin with, so hearing that moths engage in an acoustic form of it is so amazing. It makes complete sense, of course, but the fact that this form of mimicry exists in a sensory space that isn't naturally accessible to us makes it that much more alluring to learn about. These were really cool experiments, and the way they are weaved into the narrative of the video makes this a truly enjoyable watch. Great job, as always, biointeractive!
This video is put together really well! Thank you for sharing
Amazing work. I think that moths can be a great food source, but in riparian areas you may see strong selection for hunting over water such as ponds and the moths in riparian habitats may not see as high of predation in comparison to other insects.
Excellent! A very nice experiment. Good luck!
3:57 LOL acoustic warrior
3:49 I thought I was the only one who does that!
very informative.
Thank you very much for the very useful information.
I watched this video at night and the windows in my room were all closed, but there were two moths that suddenly flew randomly and approached me several times while I was watching the video. when I turn on the video, the ultrasonic sound attracts them? 😮
Awesome experiment :D
I love your documentary about flying mammal, the 🦇bat
8:30 homie got punished for his dishonesty
very interesting! could be possible to replicate the Moth Mimicry Ultrasound artificially ?
moth chan x bat kun
Wow! this stuff is pretty damn interesting!
Amazing
I’ve never seen an ultrasonic microphone …a “ bunch” of them must be costly. What are they called? Where can I find one?
video finalïsta en los science media awards (boston 2016)
Maybe it's the sound of the light that they are attracted to
These are only mammalian order which can fly
Really nice and intresting video
Glad you think so!
Good day, is there a published paper on this experiment?
Some bats used dear ears to catch moths
7:55 on is great.
What is the name of that moth's species at 1:54? Looks gorgeous
It appears to be a burnet moth there very colorful!
I love bats
In my research I see a connection to frequencies and the holy spirit, spirituality and magic. If anyone would like to comment on this subject, I would very much like to listen.
what research?
@Perfect Fresco ha, those are not real. Spirits are real and magic. Not literally magic but natural abilities like telekenisis
Such complex design your are kiddıng evolution
responsible for it
Rat off the bat pushing evolutionary theory wow
"Rat off the bat" made me think of that Ramones song.
hola vengo dde la miss susy xd no me hagan caso
Your scientific way of torturing insects in the name of science really has a bad taste ;)
