First record of Oecetis furva (Rambur, 1842) and Orthotrichia tragetti (Mosely, 1930) (Insecta, Trichoptera) for the Croatian fauna. Nat. Croat., Vol. 25, No. 1, 109–118, 2016, Zagreb

Two species, Oecetis furva and Orthotrichia tragetti, are recorded for the first time in Croatia. Moreover, O. tragetti is recorded for the first time in the limno-ecoregion Hungarian Lowlands (ER11). Adult caddisflies were collected from 2010 to 2012 in Kopački rit Nature Park. Sampling was conducted using light traps (15 W UV lamp) that were operated monthly, with the exception of May when two light trap samples were taken. Both species were collected at various habitats, from both perennial and ephemeral bodies of water (river course, lake, channels). O. furva was collected on the lower reach of the Drava River, in the eutrophic Lake Sakadaš and in two different channels ; Vemeljski dunavac (intermittent channel) and Čarna (perennial reclamation channel). O. tragetti was collected in the eutrophic Lake Sakadaš and the Čarna channel. These data represent a significant contribution to the general knowledge of caddisflies in Croatia, and particularly of insufficiently investigated wetlands and lakes in the continental region.
