Macroptery is common in many species of Orthoptera, but the causes are still discussed. Besides the assumption that macroptery is genetically determined, there is evidence that wing dimorphism is induced by environmental factors, particularly population density. However, most of the research is on pest species. In contrast, knowledge of wing dimorphism in species that occur at low population densites is still poor. Our study aims to test how density actually affects macroptery. As model…

Does wing dimorphism affect mobility in Metrioptera roeselii (Orthoptera: Tettigoniidae)?
The comparison of sexes showed that males were significantly more mobile than females, which suggests that sex-specific locomotory behaviour in M. roeselii might depend on a complex series of social interactions and physiological conditions.
Morphological variation and sex-biased frequency of wing dimorphism in the pygmy grasshopper Tetrix subulata (Orthoptera: Tetrigidae)
The results of the morphological study support the occurrence of two clearly distinct wing morphs in both sexes and demonstrate a variable frequency in the percentage of LW individuals, ranging from all-LW to all-SW populations, even if the LW morph is by far the most common morph in an area.
Spatial Variation in Body Size and Wing Dimorphism Correlates with Environmental Conditions in the Grasshopper Dichroplus vittatus (Orthoptera: Acrididae)
The spatial pattern of wing dimorphism and intraspecific morphometric variation in nine natural populations of the grasshopper Dichroplus vittatus in Argentina revealed geographic areas in which the species would experience greater dispersal capacity.
The role of macropters during range expansion of a wing-dimorphic insect species
This study is the first that quantifies the importance of macropters for the recent range expansion of a wing-dimorphic species and it provides for the first time detailed insights into the complex dispersal processes that take place at the expanding range margin.
Stable isotopes reveal dietary divergence between dispersal phenotypes in Tetrix subulata pygmy grasshoppers (Orthoptera: Tetrigidae)
It is likely that the dietary niches of the long winged and flightless individuals differ under natural conditions, which may reduce intra-specific competition, offset the expected trade-off between flight capacity and reproduction and promote ecological speciation.
Spatial sorting may explain evolutionary dynamics of wing polymorphism in pygmy grasshoppers
The findings suggest that the variable frequency of the long‐winged morph among and within pygmy grasshopper populations may reflect evolutionary modifications driven by spatial sorting due to phenotype‐ and habitat type–dependent emigration and immigration.
Asymmetric mate choice, hybridization, and hybrid fitness in two sympatric grasshopper species
The study suggests that hybridization between sympatric species might occur more often than assumed, and might affect the ecology and local distribution of animals in a similar way as competition does.
Morphological Variation Tracks Environmental Gradients in an Agricultural Pest, Phaulacridium vittatum (Orthoptera: Acrididae)
It is suggested that environmental and climatic conditions strongly influence the relative abundance and the distribution of morphotypes in P. vittatum, which is likely to affect dispersal and fitness in different landscapes.
Using citizen science data to reveal the role of ecological processes in range changes of grasshoppers and crickets in Britain
Climatic and land use changes are affecting the distributions of many species and habitats. A detailed understanding of these impacts is critical for conservation and adaptation planning, but much


Seasonal climate, followed by population density, and then their interaction with each other appear to be the three major determinants of wing morph frequencies in A. socius.
Variability in wing form of crickets
The genetic determination of the propensity for macropterism did not seem to be directly coupled to the mechanism performing the photoperiodic time-measurement, and crossing experiments indicated polygenic control of wing form as well asX-chromosomal and maternal effects.
Rapid range expansion of a wing-dimorphic bush-cricket after the 2003 climatic anomaly
It is demonstrated that macropters are of high significance for the range expansion of wing-dimorphic insects because a single-year climatic anomaly can induce strong dispersal processes.
Habitat persistence underlies intraspecific variation in the dispersal strategies of planthoppers
This study capitalized on existing intraspecific variation in the dispersal capability of Prokelisia planthoppers to examine the relationship between habitat persistence and dispersal, thereby minimizing possible phylogenetic effects and finding a highly significant negative relationship between dispersal capabilities and habitat persistence.

Control of seasonal wing dimorphism in the oriental mole cricket Gryllotalpa orientalis Brumeister (1839) from a wetland habitat in western Japan is described. The long-winged (LW) morph appeared
Density‐dependent accumulation of phase characteristics in a natural population of the desert locust Schistocerca gregaria
Investigation of phase characteristics of locusts from parents that experienced different population densities in Morocco provides more evidence for the dual roles of an individual locust's experience of crowding as well as that of its parents in density‐dependent phase change.
Changes in Dispersal during Species’ Range Expansions
The effect of population density on wing morphology differed between populations from the range core (no significant effect of density) and expanding range margins (negative density dependence), which it is proposed is part of the mechanism of the changes in dispersal.
Effects of crowding and photoperiod on wing morph and egg production in Eobiana engelhardti subtropica (Orthoptera: Tettigoniidae)
In both the morphs, reproductive traits were to some extent flexible and could be modified by photoperiodic conditions and this suggests that the SW morph is adapted to sedentary life and rapid reproduction and that the LW morph tends to migrate before or during reproduction.
Reduced flight capability in British Virgin Island populations of a wing‐dimorphic insect: the role of habitat isolation, persistence, and structure
