雄性交配的成功通常取决于领土所有权和与成功的领土防御相关的特征。经验研究表明，领地拥有者在与具有挑战性的雄性的战斗中赢得了大多数胜利。已经发现一些物理和生理特征与资源保持潜力相关。此外，在飞行昆虫中，翅膀的设计也可能对资源保持潜力有很大的影响，因为它决定了飞行过程中的效率和精度。然而，这种可能性还没有得到彻底的评估，使用现代技术的几何形态测量学分析形状。因此，本研究旨在探讨翅型是否会影响领地豆娘Calopteryx virgo（L.）（蜻蜓目：蜻蜓科）。翅膀形状和传统的飞行相关的形态措施进行了比较，27对赢家和输家从实验性的领土竞赛。与预期相反，在所有研究的机翼特征（形状，长度，宽度，总表面，展弦比和机翼载荷）中，赢家和输家之间没有差异。然而，非常显着的差异，在翅膀的形状和大小被检测到之间的前，后翅。目前尚不清楚这些差异与飞行性能的关系，因为以前的豆娘生物力学研究假设前翼和后翼具有相同的平面形状。
Male mating success is often determined by territory ownership and traits associated with successful territory defense. Empirical studies have shown that the territory owner wins the majority of fights with challenging males. Several physical and physiological traits have been found to correlate with resource holding potential. In addition, in aerial insects, wing design may also have a strong influence on resource holding potential, since it determines efficiency and precision during flight. However, this possibility has not yet been thoroughly evaluated using the modern technique of geometric morphometrics to analyze shape. Therefore, this study examined whether wing shape affects the outcome of male-male contests in the territorial damselfly, Calopteryx virgo (L.) (Odonata: Calopterygidae). Wing shape and also traditional flight-related morphological measures were compared between 27 pairs of winners and losers from experimental territorial contests. Contrary to expectations, there were no differences between winners and losers in all studied wing traits (shape, length, width, total surface, aspect ratio, and wing loading). However, highly significant differences in wing shape and size were detected between the fore- and hindwing. It is currently not known how these differences relate to flight performance, since previous biomechanical studies in damselflies assumed fore- and hindwings to have an identical planform.
