SummarySexual dimorphism of the ear of an undescribed species of zaprochiline tettigoniid is described. The internal trachea, dedicated to hearing in other tettigoniids, is unmodified in the male but fully developed in the female. The external auditory spiracle is also lost in the male. In contrast, there is no difference between the sexes in the number of sensilla within the hearing organ. The male is 10 dB less sensitive than the female. The characteristic frequency of the hearing organ at 35… 
Functional basis of the sexual dimorphism in the auditory fovea of the duetting bushcricket Ancylecha fenestrata
TLDR
Evidence is demonstrated of a pronounced auditory fovea as a sex-specific adaptation of an insect hearing organ for intraspecific acoustic communication in the duetting bushcricket Ancylecha fenestrata.
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.
Sex-specific spectral tuning for the partner's song in the duetting bushcricket Ancistrura nigrovittata (Orthoptera: Phaneropteridae)
The song of the male bushcricket Ancistrura nigrovittata consists of a sequence of verses. Each verse comprises a syllable group, plus, after about 400 ms a single syllable serving as a trigger for
What determines the tuning of hearing organs and the frequency of calls? A comparative study in the katydid genus Neoconocephalus (Orthoptera, Tettigoniidae)
TLDR
It is discussed that the frequency of male calls is strongly influenced by bat predation and by the transmission properties of the habitat but is not strongly influencedBy the tuning of the female hearing system, call frequencies of approximately 9-10kHz should be most effective as communication signals in this group of insects.
Sexual dimorphism in auditory mechanics: tympanal vibrations of Cicada orni
TLDR
Using microscanning laser Doppler vibrometry, the tympanal mechanics of Cicada orni can be characterized in controlled acoustical conditions and the small female tympa appears to be mechanically sensitive to the dominant frequency of the male calling song and to high-frequency sound, a capacity never suspected before in these insects.
The auditory system of non-calling grasshoppers (Melanoplinae: Podismini) and the evolutionary regression of their tympanal ears
TLDR
It is concluded that the auditory sensitivity of all four silent grasshopper species may be maintained by stabilising selective forces, such as predation.
What determines the number of auditory sensilla in the tympanal hearing organs of Tettigoniidae? Perspectives from comparative neuroanatomy and evolutionary forces

TLDR
Diversity in the auditory sensilla can be best addressed by comparative studies reconstructing adaptive or regressive changes in the crista acustica, and sexual and natural selection as well as allometric relationships have been identified as key factors influencing the number of sensilla.
Auditory mechanics in the grig (Cyphoderris monstrosa): tympanal travelling waves and frequency discrimination as a precursor to inner ear tonotopy
TLDR
Using laser Doppler vibrometry, micro-CT imaging of the ear and the presented data suggest that this tonotopy of the tympana drive the tonotopic mechanotransduction of the crista acustica (CA).
The tympanal hearing organ of the parasitoid fly Ormia ochracea (Diptera, Tachinidae, Ormiini)
TLDR
The similarity of the cellular organization and tympanal morphology of the ormiine ear to the ears of other tympAnate insects suggests that there are potent constraints in the design features of tyMPanal hearing organs, which must function to detect high frequency auditory signals over long distances.

Male-male behavior and sexual dimorphism of the ear of a zaprochiline tettigoniid (Orthoptera: Tettigoniidae)
TLDR
The external anatomy of the auditory system of an undescribed zaprochiline tettigoniid shows sexual dimorphism: the male appears to have no auditory spiracle equivalent to that seen in the female.
Sexual dimorphism of auditory function and structure in praying mantises (Mantodea; Dictyoptera)
TLDR
Findings support the hypothesis that ultrasonic hearing in mantises is part of a defensive system against attack by echolocating bats.

TLDR
The auditory system of C. monstrosa is a pressure receiver, adapted to low frequency sensitivity, which suggests an auditory system adapted to another function in addition to intraspecific communication.
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.
Insect hearing in the field
TLDR
The ability of the bushcricket to perceive the temporal characteristic of the call was tested with the auditory interneuron over increasing distances from a signaller and the temporal integrity of the song was found to be maintained over the whole broadcasting area.
Structure and function of the auditory system of the cicada,Cystosoma saundersii
TLDR
It is concluded that the auditory system of C. saundersii is finely adapted to the requirements of intraspecific acoustic communication with low frequency sound.
Auditory function in tettigoniidae (Orthoptera:Ensifera)
TLDR
The frequency sensitivity and the directional sensitivity of the auditory organs, for sound frequencies higher than 8–10 kHz and at threshold and suprathreshold levels, were found to be independent of pressure-gradient effects at the auditory tympana.
Bilateral coding of sound direction in the CNS of the bushcricketTettigonia viridissima L. (Orthoptera, Tettigoniidae)
TLDR
From recordings of unilaterally activated interneurons it can be inferred that the directional sensitivity of the single tympanic organ is as well tuned to this stimulus frequency of about 20 kHz, and frequency dependence of directional hearing could be confirmed on the level of the CNS.
Mating System, Mate Choice and Ultrasonic Calling in a Zaprochiline Katydid (Orthoptera: Tettigoniidae)
TLDR
Sexual communication and the mating system of an undescribed genus of zaprochiline katydid is described and it is suggested that females do not prefer calls of large males because only in the early part of the season does male song give information on the size of the male and his spermatophore glands.
An auditory giant neuron in the ventral cord ofDecticus verrucivorus (Tettigoniidae)
TLDR
The response of the neuron is unchanged along the axon stem within the thoracic and the head region of the CNS, and the cell is strongly excited on stimulation with air puffs; under these conditions responses to airborne-sound signals can be masked.
