Entomology is key to understanding terrestrial and freshwater ecosystems at a time of unprecedented anthropogenic environmental change offers substantial untapped potential benefit humanity in variety ways, from improving agricultural practices managing vector-borne diseases inspiring technological advances.We identified high priority challenges for entomology using an inclusive, open, democratic four-stage prioritisation approach, conducted among the membership affiliates (hereafter...
Pollinator behavior is vital to plant-pollinator interactions, affecting the acquisition of floral rewards, patterns pollen transfer, and plant reproductive success. During buzz pollination, bees produce vibrations with their indirect flight muscles extract from tube-like flowers. Vibrations can be transmitted flower via mandibles, abdomen, legs, or thorax directly. Vibration amplitude at determines rate release should vary coupling bee flower. This often occurs through anther biting, but no...
Bees use thoracic vibrations produced by their indirect flight muscles for powering wingbeats in flight, but also during mating, pollination, defence and nest building. Previous work on non-flight has mostly focused acoustic (airborne vibrations) spectral properties (frequency domain). However, mechanical such as the vibration's acceleration amplitude are important some behaviours, e.g. buzz where higher remove more pollen from flowers. Bee have been studied only a handful of species we know...
Significance The katydid tympanal ears have outer, middle, and inner ear components analogous to mammalian ears. Unlike mammals, each has two tympana exposed sound both externally internally, with a delayed internal version arriving via the gas-filled canal (EC). combined inputs in play significant role directional hearing. Here, we demonstrate that major factor causing delay is EC geometry. bifurcates asymmetrically, producing additional paths impose different velocities for tympanum....
Hearing loss is not unique to humans and experienced by all animals in the face of wild eclectic differences ear morphology. Here, we exploited high throughput accessible tympanal desert locust, Schistocerca gregaria rigorously quantify changes auditory system due noise exposure age. In this exploratory study, analyzed displacements, morphology Müller's organ measured activity nerve, transduction current, electrophysiological properties individual receptors. This work shows that hearing...
Determining the acoustic ecology of extinct or rare species is challenging due to inability record their signals hearing thresholds. Katydids and relatives (Orthoptera: Ensifera) offer a model for inferring species, allometric parameters sound production organs. Here, bioacoustics orthopteran Prophalangopsis obscura are investigated. This one only eight remaining members an ancient family with over 90 that dominated landscape Jurassic. The known from single confirmed specimen–the...
The auditory system of the katydid is an established model for studies hearing, predator-prey interactions, and cochlea dynamics. components peripheral to ear substantially influence hearing threshold, with internal trachea tuned calling song conspecifics, external pinnae capable enhancing ultrasounds predator detection. trade-off between such pathways has been subject multiple discussions, but received little experimental validation. In most ultrasonic katydids (Pseudophyllinae...
Resilin is an extremely efficient elastic protein found in the moving parts of insects. Despite many years resilin research, we are still only just starting to understand its diversity, native structures, and functions. Understanding differences structure diversity could lead development bioinspired polymers, with broad applications materials science. Here, better structure, offer a novel methodology for identifying resilin-rich regions insect cuticle using non-invasive Raman spectroscopy...
Early predator detection is a key component of the predator-prey arms race and has driven evolution multiple animal hearing systems. Katydids (Insecta) have sophisticated ears, each consisting paired tympana on foreleg that receive sound both externally, through air, internally via narrowing ear canal running leg from an acoustic spiracle thorax. These ears are pressure-time difference receivers capable sensitive accurate directional across wide frequency range. Many katydid species...
Stridulation is used by male katydids to produce sound via the rubbing together of their specialised forewings, either sustained or interrupted sweeps file producing different tones and call structures. There are many species Orthoptera that remain undescribed acoustic signals unknown. This study aims measure quantify mechanics wing vibration, production properties hearing system in a new genus Pseudophyllinae with taxonomic descriptions two species. The calling behaviour males were measured...
Hearing has evolved independently many times in the animal kingdom and is prominent various insects vertebrates for conspecific communication predator detection. Among insects, katydid (Orthoptera: Tettigoniidae) ears are unique, as they have outer, middle, inner ear components, analogous their biophysical principles to mammalian ear. The consists of two paired tympana located each foreleg. These receive sound externally on tympanum surface (usually via pinnae) or internally an canal (EC)....
Abstract Host–parasite associations provide a benchmark for investigating evolutionary arms races and antagonistic coevolution. However, potential ecological mechanisms underlying such are difficult to unravel. In particular, local adaptations of hosts and/or parasites may hamper reliable inferences host–parasite relationships the specialist–generalist definitions parasite lineages, making it problematic understand on global scale. Phylogenetic methods were used investigate co-phylogenetic...
The use of acoustics in predator evasion is a widely reported phenomenon amongst invertebrate taxa, but the study ultrasonic anti-predator often limited to prey bats. Here, we describe acoustic function and morphology unique stridulatory structure - Ander's organ relict orthopteran Cyphoderris monstrosa (Ensifera, Hagloidea). This species one just eight remaining members family Prophalangopsidae, group with fossil record over 90 extinct widespread during Jurassic period. We reveal that sound...
Bush-crickets have dual-input, tympanal ears located in the tibia of their forelegs. The sound will first all reach external sides tympana, before arriving at internal through bush-cricket's ear canal, acoustic trachea (AT), with a phase lapse and pressure gain. It has been shown that for many bush-crickets, AT an exponential horn-shaped morphology function, producing significant gain above certain cut-off frequency. However, underlying mechanism different designs remains elusive. In this...
Transparency is a greatly advantageous form of camouflage, allowing species to passively avoid detection regardless the properties surface which they occupy. However, it uncommon and poorly understood in terrestrial species. In one tribe predacious katydids (Phlugidini), transparency paired with highly ultrasonic communication for increased predator evasion, yet little known about singing capabilities these species, only genus Phlugidini acoustically well described date. Here, we describe...
Ensiferan orthopterans offer a key study system for acoustic communication and the process of insect hearing. Cyphoderris monstrosa (Hagloidea) belongs to relict ensiferan family is often used evolutionary comparisons between bushcrickets (Tettigoniidae) their ancestors. Understanding how this species processes sound therefore vital reconstructing history Previous investigations have found mismatch in ear species, whereby neurophysiological tympanal tuning does not match conspecific...
Bush-crickets (or katydids) have sophisticated and ultrasonic ears located in the tibia of their forelegs, with a working mechanism analogous to mammalian auditory system. Their inner-ears are endowed an easily accessible hearing organ, crista acustica (CA), possessing spatial organisation that allows for different frequencies be processed at specific graded locations within structure. Similar basilar membrane ear, CA contains mechanosensory receptors which activated through frequency...
Derived from the respiratory tracheae, bush-crickets' acoustic tracheae (or ear canals) are hollow tubes evolved to transmit sounds external environment interior ear. Due location of ears in forelegs, trachea serves as a structural element that can withstand large stresses during locomotion.

Mammalian hearing operates on three basic steps: 1) sound capturing, 2) impedance conversion, and 3) frequency analysis. While these canonical steps are vital for acoustic communication survival in mammals, they not unique to them. An equivalent mechanism has been described katydids (Insecta), it is this group among invertebrates. The katydid inner ear resembles an uncoiled cochlea, a length less than 1 mm. Their ears contain organ, crista acustica , which holds tonotopically arranged...
Abstract Insect cuticle is an evolutionary-malleable exoskeleton that has specialised for various functions. Insects detect the pressure component of sound bear sound-capturing tympani evolved from cuticular thinning. Whilst outer layer insect composed non-living chitin, its mechanical properties change during development and aging. Here, we measured displacements tympanum desert Locust, Schistocerca gregaria , to understand biomechanical changes as a function age noise-exposure. We found...
Abstract Early predator detection is a key component of the predator-prey arms race, and has driven evolution multiple animal hearing systems. Katydids (Insecta) have sophisticated ears, each consisting paired tympana on foreleg that receive sound directly externally, internally via narrowing ear canal through acoustic spiracle. These ears are pressure-time difference receivers capable sensitive accurate directional across wide frequency range, despite small size katydids. Many katydid...
