New data on bioacoustics and courtship behaviour in grasshoppers (Orthoptera, Acrididae, Gomphocerinae) from Russia and adjacent countries [PDF]
ZooKeysThe songs of seven grasshopper species of subfamily Gomphocerinae from Russia, Ukraine, Georgia, and Kazakhstan were studied. We analysed not only the sound, but also the stridulatory movements of the hind legs to more entirely describe the songs.

Songs and morphology in three species of the Chorthippus biguttulus group (Orthoptera, Acrididae, Gomphocerinae) in Russia and adjacent countries [PDF]
ZooKeys, 2021 Songs and morphology are compared between Chorthippus miramae (Vorontsovsky, 1928) that was previously named as C. porphyropterus and two other closely related species, C. brunneus (Thunberg, 1815) and C. maritimus Mistshenko, 1951.

A new species of aposematic grasshopper of the genus Pseudoutanacris (Acrididae: Gomphocerinae) from the Andean cloud forest of the Ecuadorian Amazon basin [PDF]
PeerJWe have identified a new grasshopper species belonging to the genus Pseudoutanacris Jago, 1971, in the montane forests of the eastern Andes in Ecuador. This discovery expands the known distribution of the genus, previously limited to a single species in ...

Body Temperature Differences Between Green And Brown Grasshoppers Do Not Result From Thermal Physiology or Thermal Preferences. [PDF]
Ecol EvolColour morphs could represent different life‐history strategies, maximising their fitness locally in the trait space through trade‐offs between different biological functions. This mechanism could play a role in the maintenance of the green–brown polymorphism in Orthoptera.

Energy balance of food in a detrito-bryophagous groundhopper (Orthoptera: Tetrigidae) [PDF]
PeerJ, 2020 Detritus (decaying organic matter) and phyllodes of mosses are two main components in the diet of groundhoppers (Orthoptera: Tetrigidae). We studied the energy balance of consumed food under laboratory conditions in the detrito-bryophagous groundhopper ...

The Fast Evolution of the Stenobothrini Grasshoppers (Orthoptera, Acrididae, and Gomphocerinae) Revealed by an Analysis of the Control Region of mtDNA, with an Emphasis on the Stenobothrus eurasius Group [PDF]
InsectsThe two cryptic grasshopper species of the genus Stenobothrus, S. eurasius and S. hyalosuperficies, demonstrate different acoustic behavior despite a strong similarity in morphology.

Small Bugs, Big Data: Metagenomics for Arthropod Biodiversity Monitoring. [PDF]
Ecol EvolWe used metagenomic sequencing of 40 bulk arthropod samples collected across Sweden to classify taxa and compare results with metabarcoding from the same samples. While metabarcoding was more sensitive for detecting low‐abundance taxa, taxonomic overlap between methods was strongly influenced by reference database representation.

Ecology and abundance of a relict population of the bush cricket <i>Saga pedo</i> in the Northern Apennines, Italy. [PDF]
Ecol EvolOur study reveals that the expansion of forest cover and intensification of agriculture have led to the decline of Saga pedo, a species currently listed as Vulnerable. The population of Saga pedo in the study area is estimated to be 197 individuals, but detection is challenging due to the species' elusive behavior and the impact of environmental ...

Phenotypic plasticity, heritability, and genotype-by-environment interactions in an insect dispersal polymorphism [PDF]
BMC Ecology and EvolutionBackground Evolutionary fitness is determined by the match between an organism’s phenotype and its local environment. When mismatched, individuals may disperse to more suitable habitats.
