.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 meta‐population 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.
