Sažetak
Dubrovnik-Neretva County is a small Croatian region stretching between Bosnia & Herzegovina and Montenegro, along the coastal part of southeastern Dalmatia. Historically it was one of the most often visited areas by many leading entomologists of the 19th and 20th centuries. Aside from the historical records, new surveys of butterfly diversity of this area were almost non-existent. This represents a challenge for effective local management of protected species. During the last decade, we visited the area repeatedly to gather recent data about the butterfly diversity. In order to show how much the knowledge about the butterfly fauna in the mainland part of Dubrovnik-Neretva County improved in the last decade, historical observations from the litterature were compared with recent observations. A total of 43 published references contained 680 records of 99 different butterfly species, some of which were probably erroneous. All historical records were georefferenced, in order to compare the spatial distribution of historical and newly gathered data. A grid containing 33 10x10 km squares was used for the comparison. Three main centres of research were revealed in the County: Neretva river delta, Pelje#ac peninsula and the surroundings of Dubrovnik city. During the last decade, we have gathered more than 7500 species records for the area. In total we recorded 112 species, of which 28 new species for the first time. The previously known distribution in Croatia for species like Euphydryas aurinia, Parnassius mnemosynae, Papilio alexanor, Muschampia proto and Kirinia roxelana has been greatly expanded. With a surface area of only 1.781 km1 Dubrovnik-Neretva County is one of the smallest counties in Croatia. While its surface area is slightly more than 3% of the territory of Croatia, it contains 64% species of the Croatian butterfly fauna. In the future surveys, additional species may be recorded, but no large increase in the number is expected. Out of 127 species living in the County, 11 species are categorized as nearly threatened (NT) at the European level, 113 have conservation status of least concerned (LC), while for one species category is data deficient (DD). Habitat degradation, succession and a decrease of extensive livestock grazing are recognized as the highest threats for butterflies in the area.
