“…in these two species (Cavicchi et al, 1985;Partridge et al, 1994a;James et al, 1995;van't Land et al, 1999;Zwaan et al, 2000;Navarro-Campos et al, 2011) and the general trend that insects develop larger body sizes and wings in at lower temperatures (Bergmann, 1847;Ray, 1960). A previous study of natural M. domestica populations in South America found a positive correlation between latitude and wing size in females (Alves and Bélo, 2002). Since such latitudinal clines are often related to variable temperatures, the complete lack of association between wing size and rearing temperature in our work is a bit surprising.…”

“…In line with these different behaviors, our interspecific PCA separated C. capitata and D. melanogaster (courtship songs) from M. domestica (mating strike) along PC2 that explained about 20% of the shape variation and captured differences in the ratio of wing width and wing length. Hence, the longer and narrower wings of M. domestica might be under selection for better flight performance (Alves and Bélo, 2002;Shyy et al, 2013), while the shorter and rounder wings of D. melanogaster and C. capitata seem to be better suited to displace more air for repeated buzzing (Burk and Webb, 1983;Webb et al, 1983;Wheeler et al, 1988;Talyn and Dowse, 2004;de Souza et al, 2015). Despite this potential link between interspecific wing shape differences and mating behavior, our data revealed that all three species were equally separated along PC1 that captured wing width along the proximal-distal axis and explained about 77% of the variation.…”

“…Flying helps insects to surmount long distances in a relatively short time, facilitating basic tasks, such as finding mating partners and food resources. In line with these crucial functions, wing size has been shown to be highly variable between (Houle et al, 2003;Salcedo et al, 2019) and within species (Coyne and Beecham, 1987;Imasheva et al, 1994;James et al, 1995James et al, , 1997van't Land et al, 1999;Zwaan et al, 2000;Alves and Bélo, 2002;Hoffmann and Shirriffs, 2002;Bai et al, 2016;Rohner et al, 2019). Most of our current understanding of intraspecific variation in wing size is based on extensive work in Drosophila melanogaster (Meigen, 1830).…”

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.

“…This confirms earlier studies concerning other insects (Gaston and O’Neill 2004). In Diptera, the wing measurements were used successfully for the quantification of both within and between species variations (Brown 1980; Klingenberg et al 1998; Alves and Bélo 2002; Hall et al 2014; Siomava et al 2016). The wing venation differs markedly between Diptera species, and it can be used for identification of mosquitoes (Dujardin 2011; Sumruayphol et al 2016), tephritid flies (Van Cann et al 2015), tsetse flies (Kaba et al 2016), screwworm flies (Lyra et al 2010), and stable flies (Changbunjong et al 2016).…”

Identification of Muscidae (Diptera) of medico-legal importance by means of wing measurements

Cadavers attract numerous species and genera of Muscidae, both regular elements of carrion insect assemblages, and accidental visitors. Identification of adult Muscidae may be considered difficult, particularly by non-experts. Since species identification is a vital first step in the analysis of entomological material in any forensic entomology orientated experiment and real cases, various alternative methods of species identification have been proposed. We investigated possibility of semiautomated identification by means of wing measurements as an alternative for classic morphology and DNA-based approaches. We examined genus-level identification success for 790 specimens representing 13 genera of the most common European cadavers visiting Muscidae. We found 99.8% of examined specimens correctly identified to the genus-level. Without error, the following were identified: Azelia, Eudasyphora, Graphomya, Hydrotaea, Musca, Muscina, Mydaea, Neomyia, Polietes, Stomoxys and Thricops. Genus-level misidentifications were found only in Helina and Phaonia. Discrimination of examined material on the species level within Hydrotaea (318 specimens representing eight species) and Muscina (163 specimens representing four species) showed lower, yet still high average identification success, 97.2 and 98.8%, respectively. Our results revealed relatively high success in both genus and species identification of Muscidae of medico-legal importance. Semiautomated identification by means of wing measurements can be used by non-experts and does not require sophisticated equipment. This method will facilitate the identification of forensically relevant muscids in comparison to more difficult and more time-consuming identification approaches based on taxonomic keys or DNA-based methods. However, for unambiguous identification of some taxa, we recommend complementary use of identification keys.

“…We also observed that male M. domestica wings were slightly elongated compared to female wings, additionally increasing the moment of inertia and required inertial power. Therefore, in accordance with the “mating strike” behavior in flight, M. domestica wings may be less suited for buzzing, but their wing shape might be under selection for better flight performance, that is facilitated by long and narrow wings (Alves and Bélo, 2002).…”

20The ability to powered flight facilitated a great evolutionary success of insects and allowed them to occupy 21 various ecological niches. In addition to primary tasks, wings are often involved in various premating 22 behaviors, such as courtship songs and initiation of mating in flight. These specific implications require certain 23 wing morphology, size, and shape. Although wing properties have been extensively studied in Drosophila, a 24 comprehensive understanding of sexual shape dimorphisms and developmental plasticity in wing morphology 25 is missing for other Diptera. To acquire this knowledge, we applied geometric morphometrics and analyzed 26 wing shape in three dipteran species (Drosophila, Ceratitis, and Musca) raised in different environmental 27 conditions. We extensively studied sexual dimorphism and impact of sex and environment on the adult wing 28 morphology. We present allometric and non-allometric shape differences between males and females and 29 show that wing shape is influenced by rearing conditions in a sex dependent manner. We determine common 30 trends in shape alterations and show that the anterior and posterior crossveins are likely to be plastic regions 31 changing substantially at different environmental conditions. We discuss our data in the light of vein 32 development and hypothesize that the observed shape differences might recapitulate different mating 33 behaviors and flight capabilities.
