  author={Reinhard Lakes-Harlan and Kirsten Jacobs and Geoff R. Allen},
The dipteran parasitoids Therobia leonidei and Homotrixa alleni (Tachinidae) use acoustic cues to locate their calling tettigoniid (Ensifera, Orthoptera) hosts. The sexually dimorphic tympanal organs of both fly species are located at the prosternum. For comparison a homologous chordotonal organ in the non-hearing fly Phormia regina, Meigen (Phoridae) is also described. The scolopidial sense organs of the ears have approximately 180 sensory cells in Th. leonidei and 250 cells in H. alleni… 

The evolutionary origin of auditory receptors in Tettigonioidea: the complex tibial organ of Schizodactylidae

This first investigation of the neuroanatomy of Schizodactylidae suggests a non-auditory chordotonal organ as the precursor for auditory receptors of related tympanate taxa and adds evidence for the phylogenetic position of the group.

The Auditory System of the Dipteran Parasitoid Emblemasoma auditrix (Sarcophagidae)

The anatomy and physiology of the ear at the ventral prothorax of the sarcophagid fly, Emblemasoma auditrix (Soper), using micro-computed tomography to analyze the ear and its tracheal air space in relation to the body morphology is analyzed.

Evolutionary and Phylogenetic Origins of Tympanal Hearing Organs in Insects

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.

Adaptive Strategies in Life-History of Bushcrickets (Orthoptera) and Cicadas (Homoptera) to Parasitoids Pressure on Their Acoustic Communication Systems—A Case for Sociality?

This mini-review reflects on consequences for host’s acoustic signaling in choruses using the examples of cicadas and bushcrickets and concludes that despite antagonistic selection pressure by parasitoids, singing in Choruses might select for increased, not reduced signaling in males.

Selective forces on origin, adaptation and reduction of tympanal ears in insects

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.

Auditory Parasitoid Flies Exploiting Acoustic Communication of Insects

Directional hearing relies on the mechanical coupling between the hemilateral tympana, a purely mechanical process that exploits minute interaural time differences in tympanic vibrations and enhances bilateral oscillation differences to generate a highly directional sensitivity.

Parasitoid flies exploiting acoustic communication of insects—comparative aspects of independent functional adaptations

Functional adaptations in both groups of parasitoids, Ormiini and Emblemasomatini, are reviewed and compared, indicating that their neuronal filter for the temporal patterns of the calling songs are broader than those found in intraspecific communication.



The tympanal hearing organ of the parasitoid fly Ormia ochracea (Diptera, Tachinidae, Ormiini)

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.

Tympanal hearing in tachinid flies (Diptera, Tachinidae, Ormiini): the comparative morphology of an innovation

It is proposed that, given the degree of similarity between the ormiine hearing organs, the Ormiine tribe is monophyletic, whereby all members of this tribe evolved from a common ancestor, an acoustic parasitoid of a singing orthopteran insect.

The tympanal hearing organ of a fly: phylogenetic analysis of its morphological origins

A suite of characters that define the ormiine ear are uncovered in the prothorax of Diptera, including a pair of prosternal tympanal membranes, a Pair of chordotonal sensory organs, and modifications of the tracheal system.

The histological architecture of the auditory organs in the parasitoid fly Ormia ochracea

The present results show that intersexual differences in the histoarchitecture of the sensory organs are small and are compared with some other insect auditory systems and are also discussed in terms of their significance for frequency sensitivity.

Hearing and frequency dependence of auditory interneurons in the parasitoid fly Homotrixa alleni (Tachinidae: Ormiini)

The parasitoid tachinid fly Homotrixa alleni detects its hosts by their acoustic signals, and contains auditory interneurons reacting in a wide range of temporal patterns from strictly phasic to tonic and with clear differences in frequency responses.

SummaryThis study of the ultrastructure of the auditory sensilla of the New Zealand weta, Hemideina crassidens, is the first such study on a member of the orthopteran Superfamily Gryllacridoidea.

The biology of the phonotactic parasitoid, Homotrixa sp. (Diptera: Tachinidae), and its impact on the survival of male Sciarasaga quadrata (Orthoptera: Tettigoniidae) in the field

Abstract. 1 Unlike most parasitoids, tachinid flies of the tribe Ormiini use sound to locate their hosts. Although thought to exert selection pressure on their host's calling behaviour, little is

Review of Biogeography, Host Range and Evolution of Acoustic Hunting in Ormiini (Insecta, Diptera, Tachinidae), Parasitoids of Night-calling Bushcrickets and Crickets (Insecta, Orthoptera, Ensifera)

The exploitation of cricket songs appears to be a derived pattern that evolved as a host switch some time after the Eocene, and Hypotheses concerning fly-host coevolution and the reasons for the development of hearing are discussed, and include the question of mate finding and avoidance of bats as predators.

Auditory interneurons in a hearing fly (Therobia leonidei, Ormiini, Tachinidae, Diptera)

The physiology and morphology of auditory interneurons of a fly, the parasitoid Therobia leonidei, are described for the first time and this broad hearing range matches with the peak frequencies of the song spectra of host bushcricket species.

Phonotaxis in femaleOrmia ochracea (Diptera: Tachinidae), a parasitoid of field crickets

Gravid females of Ormia ochracealocate their hosts by homing on their hosts' calling songs, proving that chirping (producing pulses in brief groups) is no safeguard from call-seeking O. och racea.
