Reduction of tympanal hearing organs is repeatedly found amongst insects and is associated with weakened selection for hearing. There is also an associated wing reduction, since flight is no longer required to evade bats. Wing reduction may also affect sound production. Here, the auditory system in four silent grasshopper species belonging to the Podismini is investigated. In this group, tympanal ears occur but sound signalling does not. The tympanal organs range from fully developed to… 
What does a butterfly hear? Physiological characterization of auditory afferents in Morpho peleides (Nymphalidae)
TLDR
It is proposed that the ears of butterflies, like those of many vertebrate prey such as some rabbits and lizards, function primarily in predator risk assessment and are capable of amplitude and frequency discrimination.
Hearing in the crepuscular owl butterfly (Caligo eurilochus, Nymphalidae)
TLDR
It is shown that the C. eurilochus ear responds to sound and is most sensitive to frequencies between 1 and 4 kHz, as confirmed by both the vibration of the tympanal membrane and the physiological response of the associated nerve branches.
Sensory evolution of hearing in tettigoniids with differing communication systems
TLDR
A significant reduction in auditory structures is shown, shaped by the differing sex roles during mate detection, in the Tettigoniidae genus Poecilimon.
Useless Hearing in Male Emblemasoma auditrix (Diptera, Sarcophagidae) – A Case of Intralocus Sexual Conflict during Evolution of a Complex Sense Organ?
TLDR
A first case is described, where a trait of an evolutionary novelty and a highly specialized hearing organ is adaptive in only one sex, and this unique hearing system might represent an intralocus sexual conflict.
Evolutionary and Phylogenetic Origins of Tympanal Hearing Organs in Insects
TLDR
Research on insect hearing is embeded in a phylogenetic framework to reconstruct the ancestral sensory situation in different taxa, and the series of morphological changes during the evolution of an ear.
Selective forces on origin, adaptation and reduction of tympanal ears in insects
TLDR
This review summarises what is known about the evolutionary origin of ears and the presumed precursor organs in the various insect groups, and focuses on selective forces for making and keeping an ear.
Neuronal Regression of Internal Leg Vibroreceptor Organs in a Cave-Dwelling Insect (Orthoptera: Rhaphidophoridae: Dolichopoda araneiformis)
TLDR
The anatomy of the most elaborate internal vibration detection system in orthopteroid insects, the scolopidial subgenual organ complex in the cave cricket Dolichopoda araneiformis, is investigated, showing for the first time that internal vibroreceptors can also be affected.
If a bird flies in the forest, does an insect hear it?†
TLDR
This is the first study to demonstrate that foraging birds generate flight sound cues that are detectable by eared insects, and it is shown that insects with both high and low frequency hearing can hear bird flight sounds.
Auditory sensitivity, spatial dynamics, and amplitude of courtship song in Drosophila melanogaster.
TLDR
It is shown that singing occurs primarily from positions resulting in direct stimulation of the female antenna, and it is established that the majority of song is louder than theoretically predicted and at these sound levels thefemale antenna should not amplify or be tuned into song.

Tympana, auditory thresholds, and projection areas of tympanal nerves in singing and silent grasshoppers (Insecta, Acridoidea)
TLDR
Findings support several authors who suggested that auditory organs evolved earlier than acoustic communication in singing and acoustically communicating grasshoppers.
Hearing in a diurnal, mute butterfly, Morpho peleides (Papilionoidea, Nymphalidae)
TLDR
It is hypothesize that Vogel's organs in butterflies such as M. peleides have evolved to detect flight sounds of predatory birds, and the evolution and taxonomic distribution of butterfly hearing organs are discussed.
Listening for males and bats: spectral processing in the hearing organ of Neoconocephalus bivocatus (Orthoptera: Tettigoniidae)
TLDR
The response properties of auditory receptor cells of Neoconocephalus bivocatus to different sound frequencies are studied, with a special focus on the frequency ranges representative of male calls and bat cries.
The Auditory System of an Atympanate Bushcricket Phasmodes Ranatriformes (Westwood) (Tettigoniidae: Orthoptera)
TLDR
The two possibilities either that this animal shows a secondary reduction of the auditory system or that it represents a primitive form are discussed, and developmental data from other tettigoniids seem to confirm the latter hypothesis.
Auditory interneurones in the metathoracic ganglion of the grasshopper Chorthippus biguttulus. I, Morphological and physiological characterization
TLDR
A comparison of branching patterns and physiological properties indicates that auditory interneurones of C. biguttulus are homologous with those described for the locust.

TLDR
Findings support the hypothesis that ultrasonic hearing in mantises is part of a defensive system against attack by echolocating bats.
How well are FREQUENCY SENSITIVITIES OF grasshopper ears tuned to species-specific song spectra?
  • Meyer, Elsner
  • Biology
    The Journal of experimental biology
  • 1996
TLDR
Hearing in acridid grasshoppers is quite well adjusted to the frequency spectra of the songs, partly because the tympanal membrane acts as a frequency filter in the low-frequency range.
Auditory characteristics and sexual dimorphism in the gypsy moth
TLDR
It is suggested that male L. dispar possess adaptively functional ears tuned to the frequencies in the echo‐location signals of bats but that the flightless females of this species are not exposed to bat predation and therefore possess ears in a state of evolutionary degeneration.
Evolutionarily conserved coding properties of auditory neurons across grasshopper species
TLDR
There must have been stabilizing selective forces at work that conserved coding characteristics and prevented an adaptation of the thoracic auditory pathway to the specific needs of acoustic communication, according to the ‘efficient coding’ hypothesis.
Evolution and function of auditory systems in insects
TLDR
Altogether, the many improvements opportunistically evolved at any stage of acoustic information-processing ultimately allow insects to come up with astonishing acoustic performances similar to those achieved by vertebrates.
