[The current flow of migrants and its contribution to Rhopalocera lepidopteran (Lepidoptera, Rhopalocera) fauna on marine islands with young allochthonous biotas].

The concept that the mechanisms limiting immigration of new Lepidoptera species are analogous for islands with different ages and degrees of endemism of their biotas is discussed. Specific features of individual species play a key role in establishment of the fauna and population on small islands rather than competitive interactions between these species. It is most likely that the species stably coexisting on an island will display similar ecological characteristics and life cycles, which complies with the concepts of the neutral theory of biodiversity and biogeography.
