Orthoptera Research and Taxonomy

A million orthopteran singers from a year of continuously operating field recorders detected, tracked and organized by song

This paper describes an unsupervised method to detect, track, and organize insect songs from continuous field recordings, identifying 10.9 million singers and 45 song types across 13 months of data.

A feedback between dispersal and hybridization may facilitate the repeated emergence of flight in field crickets

The paper investigates how dispersal and hybridization feedback loops may explain the repeated evolution of flight in Gryllus field crickets using genomic data.

Spy Crickets: Use (or not) of heterospecific acoustic cues for anti-predator responses

This study tests if crickets respond to predator vocalizations by measuring their behavior, finding they do not distinguish between predator and non-predator sounds.

Passive acoustic monitoring of Ensiferan calling diversity in a sub-tropical forest of Northeast India.

This study uses passive acoustic monitoring to analyze Ensiferan calling diversity and seasonal patterns in a subtropical forest, identifying 33 distinct call types and stable composition across seasons.

Rearing, dissection, and temporal transcriptomic profiling protocols to study density-dependent phenotypic plasticity in Schistocerca (Insecta: Orthoptera)

Comparative analysis of morphological and acoustic correlates of bush-cricket tympanic membranes

This study examines how tympanal structure, body size, and acoustic traits relate in bush-crickets, finding that surface area scales with body size while thickness is size-independent.

Husbandry and Maintenance of Carausius morosus Laboratory Populations

This paper provides standardized laboratory protocols for maintaining Carausius morosus, including husbandry, egg care, and colony sustainability.

First high-fidelity scaled 3D-printed models of insect tympanic membrane and acoustic trachea preserving their acoustic function

The paper creates high-fidelity 3D-printed models of insect tympanic membranes and acoustic trachea that replicate their acoustic function, validated through vibration and pressure mapping.

Opponent-flipping tactics in aggressive interactions of the cricket Gryllus bimaculatus

This study analyzes the kinematics of aggressive interactions in male crickets to understand how they flip opponents during fights.

Sex mosaic and a rare male in the parthenogenetic stick insect Neohirasea japonica (Phasmatodea, Lonchodidae)

This study identifies and characterizes rare male and sexual mosaic individuals in the parthenogenetic stick insect Neohirasea japonica, providing morphological and quantitative data on sexual traits.

Genomic data confirms phenotypic predictions of hybridization between cryptic Hawaiian cricket species

The paper confirms hybridization between cryptic Hawaiian cricket species using genomic data, showing genomic ancestry predicts acoustic phenotypes.

Sexual isolation maintains species boundaries between Hawaiian crickets in sympatry despite weak habitat isolation

This study shows sexual isolation, not habitat isolation, maintains species boundaries between sympatric Hawaiian crickets despite ecological overlap.

Reliable reconstruction of cricket song from biophysical models and preserved specimens

The paper tests and refines methods for reconstructing cricket song acoustics using finite element modeling and preserved specimens, finding that rehydration and parameter optimization improve reliability.

Molecular phylogenetics illuminates the evolutionary history and hidden diversity of Australian cave crickets (Orthoptera: Rhaphidophoridae)

This study uses phylogenetic analysis of mitochondrial and nuclear markers to reveal the evolutionary history and hidden diversity of Australian cave crickets, finding the fauna to be polyphyletic and identifying potential undescribed species.

Acoustic monitoring for tropical insect conservation

This paper reviews acoustic monitoring techniques for tropical insect conservation, highlighting challenges and opportunities for using insect sounds to assess biodiversity and ecosystem health.

Rthoptera: standardised insect bioacoustics in R

Rthoptera provides an open-source R package for analyzing insect acoustic signals with standardized metrics and interactive tools, improving efficiency and accessibility for researchers.

Syntopic call diversity among morphologically similar calling morphs ofthe paleotropical katydid of genus Mecopoda (Tettigoniidae) from an Indo-Burma biodiversity hotspot.

The paper describes five new syntopic calling morphs of Mecopoda katydids, finding morphological similarity but acoustic and genetic divergence.

Comparative forewing ultrastructure of high-frequency singing crickets (Eneopterinae)

This study examines the ultrastructural diversity of the harp region in Eneopterinae crickets, linking surface features to song frequency differences.

Plio-Pleistocene decline of mesic forest underpins diversification in a clade of Australian Panesthia cockroaches

This study uses phylogenetic analysis to show that Plio-Pleistocene aridification drove speciation and niche shifts in Australian Panesthia cockroaches.

Genomic evidence of speciation by fusion linked to trophic niche expansion in a recent radiation of grasshoppers

The paper uses genomic and phenotypic data to show that a grasshopper species originated from hybridization between two sister species, leading to a broader trophic niche.

The draft genome of the invasive walking stick, Medauroidea extradendata, reveals extensive lineage-specific gene family expansions of cell wall degrading enzymes in Phasmatodea

The paper reports the genome of Medauroidea extradentata, revealing lineage-specific expansions of pectinase gene families in Phasmatodea.
