Bats and moths have been engaged in aerial warfare for nearly 65 Myr. [] Key Result Preliminary data indicate that females also produce ultrasound to touch and playback of echolocation attack, but they do so with an entirely different mechanism. The anti-bat function of these sounds is unknown but might include startling, cross-family acoustic mimicry, warning of unprofitability or physical defence and/or jamming of echolocation. Hawkmoths present a novel and tractable system to study both the function and…

Anti-Bat Ultrasound Production in Moths is Globally and Phylogenetically Widespread
A long-term study across the globe, assaying moth response to playback of bat echolocation, finds preliminary evidence of independent origins of sonar jamming in at least six subfamilies, and suggests that jamming and warning are not mutually exclusive strategies.
Convergent Evolution of Wingbeat-Powered Anti-Bat Ultrasound in the Microlepidoptera
It is demonstrated that wingbeat-powered ultrasound production, likely providing an anti-bat function, appears to indeed be spread widely in the microlepidoptera; showing that acoustically active structures (aeroelastic tymbals, ATs) have evolved in at least three, and likely four different regions of the wing.
Deaf moths employ acoustic Müllerian mimicry against bats using wingbeat-powered tymbals
It is revealed how Yponomeuta moths acquire sophisticated acoustic protection despite being deaf themselves and hence unable to respond to bat attacks, and is concluded that both moth taxa are mutual Müllerian acoustic mimics.
Early erratic flight response of the lucerne moth to the quiet echolocation calls of distant bats
The crambid moth Nomophila nearctica never performed passive dives in response to frequent and loud ultrasonic pulses of >60 dB sound pressure level (SPL) that simulated the attacking echolocation call sequence of the predominant sympatric insectivorous bat Eptesicus fuscus, but rather turned away or flew erratically, regardless of the temporal structure of the stimulus.
Evolutionary escalation: the bat–moth arms race
The evolutionary history of bats and eared insects, focusing on the insect order Lepidoptera, is reviewed, and the evidence for antipredator adaptations and predator counter-adaptations are considered.
Sensing in a noisy world: lessons from auditory specialists, echolocating bats
Researchers use echolocating bats – with their adaptations for sound production and reception – as models for understanding how animals sense and communicate in noisy environments.
Simple ears - flexible behavior: Information processing in the moth auditory pathway
It is argued that Galleriinae which show negative and positive phonotaxis, are an interesting model species for future electrophysiological studies of the auditory pathway and multimodal sensory integration, and so are ideally suited for the study of the evolution of behavioral mechanisms given a few receptors.
From Understory to Canopy: In situ Behavior of Neotropical Forest Katydids in Response to Bat Echolocation Calls
Predator-prey interactions take place in complex environments, and research on the sensory ecology of predator-detection relies on understanding when, where, and how prey experience and respond to
Fuelling on the wing: sensory ecology of hawkmoth foraging
It is suggested that more experiments on hawkmoth behaviour in natural settings are needed to fully appreciate their sensory capabilities and what is presently known about the sensory organs and sensory-guided behaviour that control feeding behaviour of this fascinating pollinator taxon.
The unique sound production of the Death’s-head hawkmoth (Acherontia atropos (Linnaeus, 1758)) revisited
It is hypothesised that the uptake of viscous honey facilitated the evolution of an efficient valve at the opening of the pharynx (i.e. a modified epipharynx), and that sound production could relatively easily have evolved based on this morphological pre-adaptation.


Tiger Moth Jams Bat Sonar
Using ultrasonic recording and high-speed infrared videography of bat-moth interactions, it is shown that the palatable tiger moth Bertholdia trigona defends against attacking big brown bats (Eptesicus fuscus) using ultrasonic clicks that jam bat sonar.
Sound strategy: acoustic aposematism in the bat–tiger moth arms race
It is found that the bats only respond to the sounds of arctiids when they are paired with defensive chemistry, and the sounds are in essence a warning to the bats that the moth is unpalatable—an aposematic signal.
Tiger moth responses to a simulated bat attack: timing and duty cycle
No relationship exists between the duty cycle of a tiger moth's call (and thus the call's probability of jamming the bat) and its temporal response to bat attack, calling into doubt the assumptions behind the jamming hypothesis.
How Some Insects Detect and Avoid Being Eaten by Bats: Tactics and Countertactics of Prey and Predator
The aim with this review is to present the complex interactions between echolocating bats and insects with bat-detecting ears and show how these interactions may be advantageous for predator or prey.
Behavioral response to ultrasound by the tiger beetle Cicindela marutha dow combines aerodynamic changes and sound production.
Physiological audiograms from the auditory afferents show substantially greater sensitivity and sharper tuning than the behavioral response, which suggests that tiger beetles may use their hearing in other contexts as well as during flight.

Hearing with the mouthparts: behavioural responses and the structural basis of ultrasound perception in acherontiine hawkmoths
Structural differences suggest a convergent evolution of hearing in hawkmoths: in the place of the swollen palps of Choerocampina, acherontiine species capable of hearing possess a scale-plate of the palps that interacts with an articulating pilifer, while this modification is absent in closely related non-hearing species.

An overview of insect peripheral auditory systems focusing on tympanate ears (pressure detectors) and emphasizing research during the last 15 years is provided, suggesting that the many appearances of hearing could arise from changes in a small number of developmental modules.
The mechanics of flight in the hawkmoth Manduca sexta. I. Kinematics of hovering and forward flight.
The clearest kinematic trends accompanying increases in forward speed were an increase in stroke plane angle and a decrease in body angle and the latter may have resulted from a slight dorsal shift in the area swept by the wings as the supination position became less ventral with increasing speed.
Preliminary observations on sound production in South African hawk moths (Lepidoptera : Sphingidae)
Sound production in sphingid moths is a widespread phenomenon, but has never been investigated in the African members of the family, of which adults of both sexes are capable of producing a loud squeaking noise when in distress.
