Abstract
Caddisflies were collected in the Plitvice Lakes NP during 2008 using
emergence traps at 3 locations at tufa barriers. A total of 2217 specimens, belonging to 44 species, 27 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 for the majority of species at tufa barriers were recorded in the summer. The longest emergence period of seven months was recorded for Rhyacophila dorsalis plitvicensis and Wormaldia subnigra. Emergence patterns of the most abundant
species are in accordance with results of previous studies in the Plitvice Lakes NP. However, discrepancies in emergence patterns compared to their typical emergence patterns could be linked with the specific composition of caddisfly communities at tufa barriers.
