Sažetak
True flies (Diptera, Insecta) are regarding number of families and abundance one of the most important group of aquatic insects. The goals of this study were to determine emergence patterns and main ecological factors that influence composition and abundance of specimens and emergence of families on tufa barriers in Plitvice lakes NP. Also correlations between abundance of predator families and amount of their prey 51 were explored, as well as differences in abundance on longitudinal scale and on various microhabitats. Sampling was conducted monthly on 3 tufa barriers during 2007/2008 with 6 traps placed at each site. During both years site Barijera Novakovida Brod had highest diversity and number of families. Sampling site Barijera Novakovida Brod had the highest total catch during 2007, and site Barijera Labudovac during 2008. Overall, families Simuliidae and Chironomidae were the most abundant during the investigated period. Temperature had influence on start of emergence and duration of flight period. For families Empididae, Chironomidae and Simuliidae statistically significant correlation between abundance and current velocity was observed. Diptera families preferred all substrates except silt. Microhabitats with more prey had greater predator abundance.
