Just when you think that you are the most intelligent species
in the land, along comes the Macroglossum Stellatarum?

device to detect icebergs.
UF researcher shows hawkmoths use ultrasound to combat
bats
WRONG.
Bats and many Moths have had sonar for centuries.
Bats and moths have engaged in an arms race for nearly
65 million years as bats evolve ways to hunt down moths and moths evolve ways
to escape bats.
French physicist Paul Langévin constructed the first
sonar set to detect submarines in 1915.
By 1918, Britain and the United States had built sonar
sets that could send out, as well as receive, sound signals.
In the 2000's, the U.S. Navy introduced a sonar system
to help clear military mines.
Hawkmoths are major pollinators
and some are
agricultural pests.
Researchers use the insects as model organisms for
genetic research due to their large size.
Previous research shows tiger moths use ultrasound as
a defense mechanism.
“While they produce the sound using tymbals, a
vibrating membrane located on the thorax, hawkmoths use a system located in the
genitals.
Scientists found at least three hawkmoth species
produce ultrasonic sound, including females.
Researchers believe hawkmoths may produce the sound as
a physical defense, to warn others or to jam the bats’ echolocation, which
confuses the predators so they may not identify an object or interpret where it
is located”, Kawahara said.
