摘要：The mainland of northern Dalmatia has been surprisingly omitted from recent faunistic studies of butterfly fauna in the Croatian coastal region. In order to fill this gap we summarized our observations made in the regionduring the last two decades. Altogether 81 species were recorded, including several rare and potentially threatened species. Among these the distribution of the following species is discussed in detail: Carcharodus orientalis, Gegenes pumilio, Euchloe ausonia, Cacyreus marshalli, Tarucus balkanica, Polyommatus thersites, Euphydryas aurinia, Hyponephele lupina, and Proterebia afra. Although the butterfly diversity and conservation value of the region are not exceptionally high, some locations, in particular valleys of the Bijelina and Karišnica, could be designated as micro-reserves for conservation of high butterfly diversity including the majority of the threatened species in the region. Abandonment and subsequent overgrowing together with habitat destruction due to building of infrastructure and extensions of urban areas have been recognised as the most important factors causing butterfly declines in the region.
