The study was conducted in the southern and eastern bufor zones of the Słowiński National Park. The re- search area belongs to the least lepidopterologically recognized places of the country. In a relatively small area there is a large mosaic of habitats, which may influence the diversity of the butterflies found here. The study is a result of 35-year regular and sporadic observations. Linear transects of 100 m and 50 m in length and 5 m and 10 m in width on both sides were used in the regular study. Results of butterfly observations on transects will be described in the future. The specimens were photographed. The specimens requiring unam- biguous identification were caught using an entomological net and compared with the patterns contained in manuals for identification. A part of the specimens has been release into the environment or left as evidence, excluding protected species. The Latin nomenclature of butterflies and the layout of species were adopted from the publication of Karshlot and Razowski (1996). Polish names were used from the “Atlas motyli Pol- ski” (“The Atlas of the Polish butterflies” Buszko and Masłowski, 2008). In total 65 species of butterflies were found, including 4 protected species: Lycaena dispar, Vacciniina optilete, Boloria aquilonaris and Co- enonympha tullia and 3 mentioned in “Czerwona lista zwierząt ginących i zagrożonych”: Papilio machaon, Melitaea diamine and Apatura ilia. In the presentation of the sites, a Cartographic systems of UTM grid of 10 km per 10 km and GPS coordinates were used in the presentation of the sites. The study confirmed the presence of butterflies exchanged from this area or its neighbourhood in the early 20th century (Urbahn   and Urbahn, 1939). Many of them are related to wetlands that are characteristic of this part of the Pobrzeże Słowinskie, i.e. the outskirts of the Łebsko Lake, the areas of the Bagna Izbickie (Izbic Marshes), the Tor- fowisko Połbockie (the Pobłockie Peat Bogs) and the peatbogs of the Krakulice area. After several decades of lack of information, the Aporia crataegi (L.) appearance has been reported in the area. Diversity of habitats and low anthropopressure create good conditions for the development of many species of butterflies.
