物种形成是一个重要的进化过程，当基因流动障碍在以前的泛型种群之间进化时发生。尽管基因流动的个体屏障已经被广泛研究，但我们对隔离物种的屏障数量或这些屏障在物种内是否具有多态性知之甚少。在此，我们通过一系列的野外和实验室实验来量化Lycaeides idas和Lycaeides melissa蝴蝶之间的表型差异，并确定可能的基因流动障碍。我们发现了L. idas和L. melissa沿多个表型轴分化的证据。具体而言，我们确定了雌性产卵偏好和滞育起始的主要表型差异，以及更温和的配偶偏好差异。多表型差异可能成为基因流动的障碍，遗传距离与表型分化的相关性以及杂交羊足草群体的表型变异模式表明了这一点。虽然其中一些性状主要在物种之间存在差异（例如，滞育起始），但一些性状在同种种群之间也存在差异（例如，雄性择偶偏好和产卵偏好）。
Speciation is an important evolutionary process that occurs when barriers to gene flow evolve between previously panmictic populations. Although individual barriers to gene flow have been studied extensively, we know relatively little regarding the number of barriers that isolate species or whether these barriers are polymorphic within species. Herein, we use a series of field and lab experiments to quantify phenotypic divergence and identify possible barriers to gene flow between the butterfly species Lycaeides idas and Lycaeides melissa. We found evidence that L. idas and L. melissa have diverged along multiple phenotypic axes. Specifically, we identified major phenotypic differences in female oviposition preference and diapause initiation, and more moderate divergence in mate preference. Multiple phenotypic differences might operate as barriers to gene flow, as shown by correlations between genetic distance and phenotypic divergence and patterns of phenotypic variation in admixed Lycaeides populations. Although some of these traits differed primarily between species (e.g., diapause initiation), several traits also varied among conspecific populations (e.g., male mate preference and oviposition preference).
