N2 - The population of the Freija fritillary Clossiana freija (Thunberg, 1791) was studied in the Kivach Nature Reserve (the Republic of Karelia), where the species inhabits several sphagnum bogs and prefers sites with pronounced hummocks covered by sparse shrublets and grasses. Observations of marked individuals showed the butterflies to be quite mobile: according to an exponential model, the local residence areas were on average about 0.4 km in diameter, and the mean distance between the capture points of males and females was estimated at 0.145 and 0.084 km, respectively. An overlapping of the areas outlined for the topographically isolated sites allowed some groups to be integrated; as a result, three local populations (subpopulations) were identified as a core of the spatial structure of the studied population. Sexual differentiation during dispersal was manifested in the prevalence of males among the migrants (3.5 : 1). The mean migration distance was 0.714 km, with the greatest recorded value of 2.8 km. The model-based estimate of the butterfly dispersal distance is as great as 3 km. Such a distance ensures integration of all the subpopulations within the studied territory and dispersal of the species beyond its population boundaries.
