The diversity of diurnal Lepidoptera of Sereflikochisar District (located on the edge of the Tuz Lake, Turkey) was surveyed. In total 102 species belonging to 12 families were identified from the area. These species were recorded from six types of habitats: halophilous areas, stony and rocky slopes, agricultural lands, forest gaps, steppe areas and plantations. Preferred habitat types were evaluated and compared using Jaccard analysis. The highest species diversity was observed in steppe habitats (with 65 species). The pine plantations and stony and rocky areas had the lowest species diversity. Based on the results for the Jaccard Index, we found the least similarity between stony and rocky areas and halophilous areas. Halophilous lands and agricultural areas had the highest similarity.
