Blowflies have forensic, sanitary and veterinary importance, as well as being pollinators, parasitoids and ecological bioindicators. There is still little work with real data and from experiments assessing the relationship between blowflies' morphologic features and environmental and demographic factors. The present work tests whether the variation, in the shape and size, of Chrysomya albiceps (Wiedemann, 1819) wings is influenced by the following factors: 1) time; 2) temperature; 3) sex and; 4) different types of carcasses (pig, dog/cat and whale). Male and female wings from four different sites collected in six different years were used to obtain wing size and shape of C. albiceps. Analyses between wing shape and the variables tested had low explanatory power, even though they had statistical support. However, it was possible to identify differences in wing shape between males and females, with good returns in sex identification. The comparison between wing size and the variables tested showed that wing size has a negative relationship with temperature, significant differences between sexes, slight variation over time and no influence by carcass types. Furthermore, wing size influenced wing shape. Understanding population-specific characteristics of C. albiceps provide important insights about how the species reacts under specific conditions.
丽蝇具有法医、卫生和兽医方面的重要性，同时也是传粉者、寄生蜂和生态生物指示物种。目前，利用实际数据和实验来评估丽蝇形态特征与环境及人口统计学因素之间关系的研究仍然很少。本研究旨在测试白纹伊蚊（Chrysomya albiceps，维德曼，1819年）翅膀的形状和大小变化是否受以下因素影响：1）时间；2）温度；3）性别；4）不同类型的尸体（猪、狗/猫和鲸鱼）。研究使用了在六个不同年份从四个不同地点采集的雄性和雌性翅膀，以获取白纹伊蚊翅膀的大小和形状。尽管在统计学上有支持，但翅膀形状与所测试变量之间的分析解释力较低。然而，有可能识别出雄性和雌性翅膀形状的差异，在性别鉴定方面有良好的效果。翅膀大小与所测试变量的比较表明，翅膀大小与温度呈负相关，两性之间存在显著差异，随时间略有变化，且不受尸体类型的影响。此外，翅膀大小影响翅膀形状。了解白纹伊蚊特定种群的特征，有助于深入了解该物种在特定条件下的反应。
