New species of caddisflies (Insecta: Trichoptera) for Croatian fauna from the Kopački rit Nature Park

Adult Tularis (Trichoptera) were collected in the period from 2010 to 2012 in the area of the Kopački rit Nature Park at a total of 8 stations. These are the first studies of the fauna and ecology of the tular in the area of the park, which included different types of freshwater habitats. Sampling was done using a light trap (UV lamp BLB 15 W) once a month, except for May when sampling was done twice. Two species recorded in this research are new to the fauna of Croatia: Oecetis furva and Ortotrichia tragetti. Both species were recorded in different types of habitats (river course, lake, canals). The species Oecetis furva was recorded on the lower reaches of the Drava River, then on a eutrophic lake (Sakadaška jezera), an occasional watercourse with small pools (Vemeljski Dunavac) and a canal with an occasional flow (Čarna canal). The species Ortotrichia tragetti was recorded in a eutrophic lake (Lake Sakada) and a canal with intermittent flow (Čarna canal). These data represent a significant contribution to the knowledge of the tular fauna of Croatia in general, and in particular to the insufficiently researched wetland and lake habitats of the continental part of Croatia.
