New data on the distribution of Drusus discolor in Croatia The second recorded species from the genus Drusus in this study was D. discolor at the spring site of the Čabranka River ( Figure 4 ). This finding only confirmed the presence of this species at the investigated site, as it was recorded in previous research ( Previšić & Popijač 2010 ). Apart from the spring area of the Čabranka River, D. discolor was first found in Croatian fauna in the larval stage in the Mrežnica River ( Habdija 1979 ) and in the adult stage at the spring of the Dobra River ( Cerjanec et al. 2020 ). According to the distribution, D. discolor most probably has the widest distribution ( Graf et al. 2021 ) among all species of the genus Drusus . The larva is characterized by a very pronounced area with small, thick, yellow hairs on the head in which it collects some organic matter and small invertebrates which it "removes" with especially adapted forelegs with large and strong hairs. According to the feeding type , it belongs to the carnivorous caddisflies ( Vitecek et al . 2015a ). Both sexes of the adult stage, as well as the larva, are well known and described ( Malicky 2004 ; Vitecek et al . 2015a ; Waringer & Graf 2011 ).
