The Effects of Diet on the Expression of Male Dimorphic Colouration and Weaponry in a Species of Neotropical Katydid. [PDF]

Ecol Evol
Male alternative reproductive tactics are widespread, often involving distinct morphs influenced by genetics or the environment. This study confirms two male morphs in the bush cricket Satizabalus jorgevargasi—larger, more colourful majors and smaller, duller minors—and tests how diet affects their development.

Combining Time-Stamped Insect Sampling With eDNA-Metabarcoding of Guano to Reconstruct Community Interactions. [PDF]

Ecol Evol
ABSTRACT Understanding the temporal dynamics of predator–prey interactions is the basis for predicting behavioral responses to climate or other environmental changes. Bats, as generalist apex predators, can provide a holistic view on ecosystem health, because their diet integrates signals from diverse insect communities and rapidly reflects ...

Replicated Differential Expression Analysis in a Green-Brown Polymorphic Grasshopper Reveals Role of Beta-Carotene-Binding Protein in Body Coloration. [PDF]

Mol Ecol
ABSTRACT Orthoptera provide a well‐documented case of transspecies colour polymorphism, with green and brown morphs coexisting in many species. This colour polymorphism is likely under long‐term balancing selection, but the genetic and molecular mechanisms underlying the variation remain poorly understood.

Tribal affiliation of endemic Macaronesian bush-crickets similar to Tettigonia (Orthoptera: Tettigoniidae) based on their karyology and taxonomy

European Journal of Entomology, 2020
Two endemic genera of large tettigoniids are found in the Canary Islands and Madeira, which are morphologically similar to the genus Tettigonia. In this study, the karyotypes of representatives of the Glyphonotini genera Calliphona and Psalmatophanes are

Identifying Key Biodiversity Areas Based on Distinct Genetic Diversity. [PDF]

Mol Ecol Resour
ABSTRACT Key Biodiversity Areas (KBAs) are sites that contribute significantly to the global persistence of biodiversity. Distinct genetic diversity has been introduced as one of the metrics to estimate whether a site holds a threshold proportion of a species' global genetic diversity during the KBA identification process.

Hunting from the air: A new record of predation of Agelaia testacea (Fabricius, 1804) (Vespidae: Polistinae) on a katydid Parascudderia sp. (Orthoptera: Tettigoniidae: Phaneropterinae) in the Peruvian Amazon

Entomological Communications, 2022
Social wasps capture adult and/or immature insects to feed their larvae. Frequent observations indicate mainly small or immature insects as their prey. However, there are very few records of social wasps as predators of larger living insects. Herein, we

Increased copulation duration before ejaculate transfer is associated with larger spermatophores, and male genital titillators, across bushcricket taxa [PDF]

, 2011
Copulation duration varies considerably across species, but few comparative studies have examined factors that might underlie such variation. We examined the relationship between copulation duration (prior to spermatophore transfer), the complexity of ...

Comparison of the mating behaviour of a bush cricket in the laboratory and the field: Calling activity and mating frequency of a long-winged species, Phaneroptera falcata (Ensifera: Tettigoniidae)

European Journal of Entomology, 2014
Bush crickets are a model group for testing hypotheses in sexual selection, but much of the information is based on laboratory observations on wingless or short-winged species, which may restrict their generality.
