翅膀干涉图是昆虫透明翅膀的稳定结构色反射。机翼的颜色是薄膜干涉的结果，并根据机翼厚度和其他机翼特性而变化。这些图案被认为在求偶过程中起着展示的作用。最近的实证研究得出结论，WIPs影响雄性果蝇的吸引力，果蝇的进化是由性选择驱动的。然而，这些研究并没有考虑到身体大小的变化，一个变量，已被证明是性别选择，这可能与翅膀厚度和羽毛颜色。我在这里考虑的可能性，身体大小可能是在这些研究中被选择的性状，而不是WIPs，后者是间接选择的。考虑这一备择假设的第一步是证明WIPs和体型之间的相关性。我分析了这种相关性是否存在通过系统发育树的genusConiceromyia（双翅目：Phoridae）通过比较进化模型假设依赖和独立的两个特征的进化。我还调查了WIPs是否与本属的两个物种内的身体大小。强有力的证据被发现有利于在分析的树和两个物种之一的WIPs和身体大小之间的相关性。如果这些结果被证实为一般模式，WIPs的信号作用及其与性选择的直接关系可能会受到最近研究实验中身体大小可能是性选择特征的替代假设的质疑。
Wing interference patterns (WIPs) are stable structural color reflections of insect transparent wings. The WIP colors are the result of thin‐film interference and vary according to wing thickness and other wing characteristics. These patterns have been thought to play a display role during courtship. Recent empirical studies concluded that WIPs affect male drosophilid attractiveness and that WIP evolution is driven by sexual selection. However, these studies did not account for body size variation, a variable that has been demonstrated to be sexually selected and that may be related to wing thickness and WIP color. I consider herein the possibility that body size could be the trait being selected in these studies, and not the WIPs, with the latter being indirectly selected. A first step to consider this alternative hypothesis would be to demonstrate the correlation between WIPs and body size. I analyzed whether such correlation exists through the phylogenetic tree of the genusConiceromyia(Diptera: Phoridae) by comparing evolutionary models assuming dependent and independent evolution of both traits. I also investigated whether WIPs are correlated to body size within two species of this genus. Strong evidence was found in favor of the correlation between WIPs and body size in the tree analyzed and within one of the two species. If these results are confirmed as a general pattern, the signaling role of WIPs and their direct relation to sexual selection may be questioned by the alternative hypothesis that body size could be the sexually selected trait in recent studies' experiments.
