在雌性羽化时间随机波动的环境下，分析了单线蝶雄性羽化时间的进化稳定性。利用突变不可达性标准计算的ESS出现曲线显示，在其占主导地位的种群中，它是使平均对数终身交配成功率最大化的曲线。如果雄性对雌性每年的羽化时间表有准确的信息，它们的羽化曲线将进化到一个确定性博弈模型所预测的曲线。然后雄性的出现曲线会在年份之间发生变化，与雌性出现模式的年复一年的变化密切相关。相反，如果雄性对雌性羽化时间表存在不确定性，则ESS雄性羽化曲线比确定性博弈模型预测的曲线更宽，并且不能很好地跟踪雌性羽化的年间波动。在一个特殊情况下，我们展示了平均羽化日期的年际变化、羽化日期的方差、平均羽化日期的性别差异（亲代）和两性平均羽化日期的年际相关性如何随着雄性可获得信息的准确性而变化。
The evolutionarily stable (or ESS) emergence schedule for males of univoltine butterflies is analysed in an environment in which the female emergence schedule fluctuates stochastically between years. The ESS emergence curve, computed using the mutant invadability criterion, is shown to be the one that maximizes mean logarithmic lifetime mating success in the population in which it dominates. If males have accurate information about the female emergence schedule within each year, their emergence curve would evolve to the one predicted by a deterministic game model. The male emergence curve would then shift between years, closely following year to year changes in the female emergence pattern. If, instead, males have uncertainty about the female emergence schedule, the ESS male emergence curve becomes broader than the one predicted by the deterministic game model and will not track the between-year fluctuation of female emergence well. In a special case, we show how the between-year variation of mean emergence date, the variance of emergence date, the sexual difference in mean emergence dates (protandry) and the between-year correlation of mean emergence dates of both sexes should change with the degree of accuracy of information available to males.
