Sažetak
Caddisflies were collected in the Plitvice Lakes NP during 2008 using emergence traps at 6 locations at tufa barriers and lakes. A total of 2265 specimens, belonging to 44 species, 25 genera and 12 families were recorded during this study. Six species, Hydroptila cognata, Hydroptila occulta, Ecnomus tenellus, Potamophylax luctuosus, Beraeodes minutus and Ceraclea annulicornis are new to the caddisfly fauna of the Plitvice Lakes NP. The highest number of species and individuals were collected at Labudovac barrier and diversity was highest at Labudovac and Novakovića Brod barriers. Emergence peaks were recorded in the summer and in the late spring and summer at tufa barriers and lakes, respectively. Emergence patterns of the most abundant species are in accordance with results of previous studies in the Plitvice Lakes NP. At tufa barriers, trichopteran community was dominated by collectors filterers, and at lakes by predators – collectors filterers, shredders – predators – scrapers and scrapers – xylophagous.
