“…Geometric morphometric variation in wings has been attributed to environmental heterogeneity in a number of butterfly species (Vandewoestijne & Van Dyck 2011; Bai et al 2015). We found that the forewings of S. diana females from high elevations were narrower than those of females from lower elevations.…”

A quantitative analysis of wing variation in grasshoppers can help us to understand how environmental heterogeneity affects the phenotypic patterns of insects. In this study, geometric morphometric methods were used to measure the differences in wing shape and size of Trilophidia annulata among 39 geographical populations in China, and a regression analysis was applied to identify the major environmental factors contributing to the observed morphological variations. The results showed that the size of the forewing and hindwing were significantly different among populations; the shape of the forewing among populations can be divided into geographical groups, however hindwing shape are geographical overlapped, and populations cannot be divided into geographical groups. Environmental PCA and thin-plate spline analysis suggested that smaller individuals with shorter and blunter-tip forewings were mainly distributed in the lower latitudes and mountainous areas, where they have higher temperatures and more precipitation. Correspondingly, the larger-bodied grasshoppers, those that have longer forewings with a longer radial sector, are distributed in contrary circumstances. We conclude that the size variations in body, forewing and hindwing of T. annulata apparently follow the Bergmann clines. The importance of climatic variables in influencing morphological variation among populations, forewing shape of T. annulata varies along an environmental gradient.Environmental heterogeneity and ecological gradients can generate phenotypic variation in many organisms [1][2][3] . Understanding how environmental heterogeneity affects phenotypic patterns in organisms is a major focus in evolutionary ecology [4][5][6][7] . Under certain environment, phenotype changes can increase fitness in organisms [8][9][10][11] . Phenotypic clinal patterns associated with environmental gradients are often described as ecogeographical rules known as Bergmann's rule or converse-Bergmann' s rule [12][13][14][15] . Bergmann's rule was initially used to explain the relationship between changes in the body size of endotherms and changes in latitude and altitude; it described a positive relationship between body size and latitude, in which smaller individuals are typically found at lower latitudes where climates are generally warmer. A number of studies have shown that the body size of insects along environmental gradients fit Bergmann clines or converse-Bergmann clines, but other studies have suggested that Bergmann's rule might not work in insects 16,17 . These ecogeographical rules have been extensively examined and convincingly demonstrated in insects 18 . However, morphological variations within insect species might reflect different patterns of dispersal and habitat availability coupled with different life-history types (e.g., hemimetabolism or holometamorphosis). The adaptive significance of these clines in insects has been fiercely debated 19,20 . Shelomi claimed that researches on these ecogeographical rules in insects should focus on widesprea...

“…Recent study on dimorphism in the shape of the wings in Lucilia sericata using geometric morphometric methods showed that the variations observed could be genetic or could be mere reflections of the existence of high phenotypic plasticity due to environmental changes during growth and development of the larvae [19]. Similar study was conducted on the body size and wing shape of Pieris rapae [20] and Lymantria dispar [21]. The study on the molecular protein chaperone Hsp90 was used to analyze the effects on the variations on the individuals and fluctuating asymmetry of wing shape of Drosophila melanogaster and showed that mutations were observed [22].…”

The present investigation attempted to evaluate the genotoxicity effect of ecdysone agonist, on the wing architecture using the land mark based shape analysis through geometric morphometrics. The study revealed that the fore and hind wings of treated male and female showed significant variation in shape. High significance in shape was observed in male fore and hind wings. But, variation in size was not affected. The analysis of symmetry and asymmetry between left and right wings, suggests that the untreated male exhibit shape difference between left and right forewings and similar variation was also found in forewings of treated female. These findings demonstrate that, chromafenozide treated on the egg masses produced genotoxic effect on the adult wing architecture of C. cephalonica. Both the male and female forewing showed high significant shape decomposition at P = 0.0001 level exposed to 1/5 EC50 of chromafenozide. The morphological alteration in wing shape suggests that, it affects the aerodynamics pattern of the insect. In the present study, species diagnosis was performed in laboratory reared F1 generation using multilocus barcoding technique and obtained a sequence of 658bp (CO I) and 563bp (18s) in length.
