1.对凤蝶Pararge aegeria的最大加速能力与飞行形态的关系进行了实验研究。这种关系常常被假定，但很少被检验。在两种性别的加速能力呈正相关，总身体质量，胸部质量，前翼面积，前翼长度，翼负荷，展弦比和中心的前翼面积（质心）。与总身体质量，前翅面积，前翅长度和翼负荷的关系在男性更强。这可以通过不同的质量分配来解释：雄性将更多的质量分配给胸部，雌性将更多的质量分配给胸部.通过多变量分析，发现形态性状对加速能力的综合效应的证据。在男性和女性，更远的相对质心和更高的相对胸部质量与较高的飞行能力。此外，长径比与加速能力仅在男性中呈正相关.我们的研究结果支持背后的飞行形态和交配定位行为之间的关系假设的机制。
1. The relationship between maximal acceleration capacity and flight morphology was tested experimentally in the butterfly Pararge aegeria . Such relations are often assumed but seldom tested.2. In both sexes acceleration capacity was positively correlated with total body mass, thorax mass, forewing area, forewing length, wing loading, aspect ratio and centre of forewing area (centroid). Relationships with total body mass, forewing area, forewing length and wing loading were stronger in males. This can be explained by different mass allocation: males allocate proportionally more mass to the thorax, females more to the abdomen.3. Evidence for the combined effect of morphological traits on acceleration capacity was found by multivariate analysis. In males and females, a more distant relative centroid and higher relative thorax mass were related to a higher flight capacity. In addition, aspect ratio was positively related to acceleration capacity in males only.4. Our results support the assumed mechanism behind the relationship between flight morphology and mate-locating behaviour.
