16 Feb 2015 Using high-speed infrared cameras, researchers at Boise State University watched big brown bats hunt moths by means of echolocation.
How to play Choose one person to be a bat. This person wears the blindfold. Everyone else is a moth. The person who is a bat stands in the centre and calls out “bat” to those who are moths. When the bat calls, the moths reply “moth.” The bat has to try to catch the moths, and the moths should do

They collected two species of tiger moths: Pygarctia roseicapitis and Cisthene martini. the bat to simulate its weak sense of sight. In order to find the moth, the bat must use echolocation by saying “BAT.” Every time the bat speaks, its signal is hitting the moths and they must respond by saying “MOTH.” The bat blindly moves around the circle trying to catch its prey.
For nearly 65 million years, bats and tiger moths have been locked in an aerial arms race: Bats echolocate to detect and capture tiger moths, and tiger moths evade them with flight maneuvers and
Attempting to control bats with moth balls is ineffective, illegal and will just put you at risk. The moth sounds could also interfere with, or "jam," bat sonar, but evidence for such jamming has been inconclusive. Using ultrasonic recording and high-speed infrared videography of bat-moth interactions, we show that the palatable tiger moth Bertholdia trigona defends against attacking big brown bats (Eptesicus fuscus) using ultrasonic clicks that jam bat sonar.
For over 50 million years, bats and moths have been engaged in an evolutionary arms race. A study in the journal Science identifies another weapon in the moth arsenal: the ability to jam bat sonar.
1). Mixed-effects logistic regression revealed a moth without tails is 8.7 times [confidence interval (CI) = 2.1–35.3] more likely to be captured than a moth with tails. During each foraging session, we presented a bat with one intact luna moth, one luna moth with its tails ablated, and 1–2 pyralid moths as controls. Control For over 50 million years, bats and moths have been engaged in an evolutionary arms race.

2018-12-28 · A bat uses its larynx to produce ultrasonic waves that are emitted through its mouth or nose. Some bats also produce clicks using their tongues. The bat hears the echoes that are returned and compares the time between when the signal was sent and returned and the shift in the frequency of the sound to form a map of its surroundings. Moths Block Bats' Sonar. A hungry bat screeches out ultrasonic waves and listens as they echo off surrounding objects. One of those echoes sounds an awful lot like a tasty moth, so it swoops in
Moth clicks were played through a loudspeaker as bats tried to capture mealworms catapulted through the air. Moth clicks caused bats to veer away from the mealworms, but echolocation calls played through the speaker did not, causing the authors to conclude that the moth clicks themselves dissuaded the bats.

Three mechanisms have been proposed: (1) the phantom echo hypothesis, which states that bats misinterpret moth clicks as echoes; (2) the ranging interference hypothesis, which states that moth clicks degrade the bats' precision in determining target distance; and (3) the masking hypothesis, which states that moth clicks mask the moth echoes entirely, making the moth temporarily invisible.

Even more interesting, the predator-prey relationship of bats is co-evolutionary. Just as many moth families developed ears to detect bats over time, many bat species evolved over time to counter moth evasion.
