摘要从植物分布、花蜜数量、花蜜的碳水化合物(和氨基酸)含量以及所利用和避免的植物的视觉格局等方面，研究了两种不同山地生态系统中Colias蝴蝶对花蜜的取食偏好。Colias，显然还有许多其他小型的，外热的，低能量需求的传粉者，“光顾”生产相对稀薄的蜜汁的植物，含有高比例的单糖和大量的极性，富氮的氨基酸。这些植物在紫外光和人类可见光下也会聚在一起形成一个共同的“目标”花朵图案。相比之下，高能量需求的吸热型授粉者似乎需要更高浓度的蜜汁和/或更高比例的二糖和低聚糖。根据不同传粉者的水分平衡和能量平衡需求对这些结果进行了讨论。还提出了有关传粉者寻找资源的行为方面的问题，以及这些数据与花拟态概念的相关性。
SummaryNectar foraging preferences of Colias butterflies in two different mountain ecosystems are examined with respect to plant distribution, nectar quantity, carbohydrate (and amino acid) content of nectar, and visual pattern of the plants utilized and avoided. Colias, and apparently numerous other small, ectothermic, low-energy-demand pollinators, “patronize” plants producing relatively dilute nectars containing a high proportion of monosaccharide sugars and significant amounts of polar, nitrogen-rich amino acids. These plants also converge on a common “target” flower pattern in ultraviolet and human-visible light. High-energy demand, endothermic pollinators, by contrast, appear to require higher concentration nectars and/or higher proportions of di- and oligosaccharide sugars. These results are discussed in the light of water balance and energy budget demands of different pollinator classes. Questions are also raised concerning behavioral aspects of pollinator search for resources and the pertinence of these data to the concept of floral mimicry.
