“…In accordance with previous observations (Bitner-Mathé and Klaczko, 1999;Gilchrist et al, 2000;Gidaszewski et al, 2009;de Camargo et al, 2015;Siomava et al, 2016;Pieterse et al, 2017;Lemic et al, 2020;Rohner, 2020;Cortés-Suarez et al, 2021), we detected a clear sexual dimorphism in wing size and shape in all three species, which was most pronounced in C. capitata. Sexual dimorphism in wing shape is most likely functionally relevant because it is widespread in insects (Cowley et al, 1986;Pretorius, 2005;Bogdanović et al, 2009;Gidaszewski et al, 2009;Ribak et al, 2009;Allen et al, 2011;Benítez et al, 2011;de Camargo et al, 2015;Gallesi et al, 2015;Virginio et al, 2015;Lorenz et al, 2017;Rodríguez and Liria, 2017;Pajač Živković et al, 2018).…”

“…In addition to sexual wing size dimorphism (Siomava et al, 2016), D. melanogaster exhibits a clear wing shape dimorphism with male wings being broader than female wings (Bitner-Mathé and Klaczko, 1999;Gilchrist et al, 2000;Gidaszewski et al, 2009). Given that males of C. capitata produce courtship songs like D. melanogaster, it is not surprising that similar trends in wing size and shape have been observed in this species (Siomava et al, 2016;Pieterse et al, 2017;Lemic et al, 2020). Wing size (Siomava et al, 2016;Cortés-Suarez et al, 2021) and shape (Rohner, 2020;Cortés-Suarez et al, 2021) are also sexually dimorphic in M. domestica.…”

Conserved and Divergent Aspects of Plasticity and Sexual Dimorphism in Wing Size and Shape in Three Diptera

The ability of powered flight in insects facilitated their great evolutionary success allowing them to occupy various ecological niches. Beyond this primary task, wings are often involved in various premating behaviors, such as the generation of courtship songs and the initiation of mating in flight. These specific functions imply special adaptations of wing morphology, as well as sex-specific wing morphologies. Although wing morphology has been extensively studied in Drosophila melanogaster (Meigen, 1830), a comprehensive understanding of developmental plasticity and the impact of sex on wing size and shape plasticity is missing for other Diptera. Therefore, we raised flies of the three Diptera species Drosophila melanogaster, Ceratitis capitata (Wiedemann, 1824) and Musca domestica (Linnaeus, 1758) at different environmental conditions and applied geometric morphometrics to analyze wing shape. Our data showed extensive interspecific differences in wing shape, as well as a clear sexual wing shape dimorphism in all three species. We revealed an impact of different rearing temperatures on wing shape in all three species, which was mostly explained by plasticity in wing size in D. melanogaster. Rearing densities had significant effects on allometric wing shape in D. melanogaster, while no obvious effects were observed for the other two species. Additionally, we did not find evidence for sex-specific response to different rearing conditions in D. melanogaster and C. capitata, while a male-specific impact of different rearing conditions was observed on non-allometric wing shape in M. domestica. Overall, our data strongly suggests that many aspects of wing morphology underly species-specific adaptations and we discuss potential developmental and functional implications of our results.

“…As discussed in Mikac et al [ 49 ] for coleopteran species and in Lemic et al [ 42 ] for dipteran species, it is thought that bigger wings are probably more aerodynamic and may also be useful for mated females that are known to engage in migratory flights. Considering presented results and based on literature review [ 43 , 49 , 50 , 51 , 52 ], this study provides opposite morphological evidence than shown in Hernández et al [ 21 ] that the migration in T. infestans can be attributed to the females of this species.…”

“…Results showed that females are larger than males (discussed in Djuradin et al [ 9 ]). In species like insects, a sexual dimorphism observed in smaller size and shape of males is often revealed in many species of Diptera, Lepidoptera, Hymenoptera and Coleoptera [ 37 , 38 , 39 , 40 , 41 , 42 , 43 ]. After further analyses, this survey found that sexual dimorphism depends on geographic region.…”

Morphometrics has been used on Triatomines, a well-known phenotypically variable insect, to understand the process of morphological plasticity and infer the changes of this phenomenon. The following research was carried out in two regions of the inter-Andean valleys and two Chaco regions of Chuquisaca-Bolivia. Triatoma infestans adults were collected from the peridomestic (pens and chicken coops) along a geographic gradient in order to evaluate the morphological differentiation between groups and their pattern of sexual shape dimorphism. Geometric morphometric methods were applied on the wings and heads of T. infestans. The main findings include that we proved sexual dimorphism in heads and wings, determined the impact of environmental factors on size and shape and validated the impact of nutrition on head shape variation. These results show that geometric morphometric procedures can be used to provide key insight into the biological adaptation of T. infestans on different biotic (nutrition) and abiotic (environment) conditions, which could serve in understanding and evaluating infestation processes and further vector control programs.

“…This tool provides data by measuring the distance between well-defined specific points (markers) placed at the intersections of veins on the wings. Since geometric morphometrics has been frequently and successfully used in the last decade to study various body parts of many insect species, particularly the wings [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 ], it is an ideal tool for describing the phenotypic plasticity of H . axyridis .…”

The Asian ladybird (Harmonia axyridis Pallas), native to Asia, is one of the 100 most invasive species in the world and has spread worldwide. This study aimed to characterize color forms of H. axyridis in Croatia and to analyze the variability of wing shape between populations and indicated forms. Geometric morphometric methods were used to analyze a total of 129 left and right wings in males and 126 left and right wings in females of H. axyridis collected from four different sites in Croatia. The results show a significant difference in wing shapes between the studied forms. Each form had its own specific morphotype that likely originated under the influence of genetic changes in the species. This study demonstrates that the use of geometric morphometric analysis is effective in studying the variability in H. axyridis populations. As this study is the first of its kind, for further clarity, it is necessary to conduct additional studies on a larger number of sites and an equal number of individuals of all forms.
