1. 研究了一种单食蝴蝶——沼泽贝母（Proclossiana eunomia）在一个由云杉人工林或施肥的牧场分隔开的适宜生境斑块上的种群结构。通过标记-释放-再捕获技术，发现了栖息地斑块之间意想不到的高水平成虫运动。当地种群通过跨越不适宜栖息地的成年迁移而联系在一起，导致了一种超种群结构。这种专业蝴蝶的超种群结构的证据挑战了栖息地专业化与封闭、孤立种群之间的假定关系。雄性和雌性的空间行为存在差异；与男性相比，女性更有可能移居海外并分散得更远。这些空间行为的差异与交配系统有关。
1. The structure of local populations of a monophagous butterfly, the bog fritillary Proclossiana eunomia, was studied in a complex of suitable habitat patches separated by spruce plantations or fertilized pasture.2. An unexpected high level of adult movements between habitat patches was detected by a mark-release-recapture technique. Local populations were connected by adult movements across unsuitable habitats, leading to a metapopulation structure.3. This evidence of the metapopulation structure of a specialist butterfly challenges the supposed relationship between habitat specialization and closed, isolated populations.4. Males and females of P.eunomia exhibited different spatial behaviours; females were more likely to emigrate and dispersed further than males. These differences in spatial behaviour are related to the mating system.
