在瑞典中部的一个种群中，Leptidea sinapis L.利用不同的区域产卵和取食。大部分卵（90.4%）产在生长在草地上的植物上，而大部分花（96.0%）则生长在邻近的树林中。除了被专门化，以利用空间上分离的地区为“繁殖”和“觅食栖息地”，蝴蝶种群表现出专业化的资源利用在这两种栖息地类型。在14种蝶形花科植物中，只有6种产卵，其中87.3%的卵产在一种植物（草地山豌豆）上。同样地，在60朵可利用的花中，只有13朵被成虫取食，88.8%的访花者是山莴苣，紫花堇菜和犬弧菌V.canina L.成年人和幼虫喂养专业化的进化方面进行了讨论，特别是参考“资源的可预测性”和昆虫和植物之间的共同进化关系。
In a central Swedish population of Leptidea sinapis L. different areas were utilized for ovipositing and feeding. The majority of the eggs (90.4 %) were laid on plants growing in a meadow, whereas the greater part of the flowers visited for feeding (96.0 %) were growing in the adjacent woods. In addition to being specialized so as to utilizing spatially separate areas for "breeding" and "foraging habitats", the butterfly population exhibited specializations with respect to resource utilization in both habitat types. Thus, only six out of fourteen available papilionaceous plants were oviposited on, 87.3 % of the eggs being laid on one species (Lathyrus pratensis L.). Likewise, only thirteen out of some sixty available flowers were fed on by the adults, 88.8 % of the flower visits being made to Lathyrus montanus Bernh., Viola riviniana Rchb. and V. canina L. The evolutionary aspects of adult and larval feeding specializations are discussed with particular reference to "resource predictability" and the coevolutionary relationship between insects and plants.
