Kladarić, Lidija, Popijač, Aleksandar, Hlebec, Dora, Previšić, Ana, Ćuk, Renata, Vučković, Ivan & Kučinić, Mladen, 2021, A surprising finding of Ecclisopteryx asterix Malicky, 1979 (Insecta, Trichoptera) in Croatia with notes to DNA barcoding and new distributional data of the subfamily Drusinae, Ecologica Montenegrina 48, pp. 71-85 : 78

2.3. New data on the distribution of Drusus schmidi in Croatia

The third species, D. schmidi Botosaneanui, 1953 , was recorded during this research at four localities in the area of the Papuk Mt. and at one locality in the area of the Krndija Mt. in the continental-lowland part of Croatia ( Figure 4 ). Previous research has recorded this species in the Papuk Mt. area at two locations, the Dubočanka Stream and the Jankovac Spring ( Previšić et al. 2013), and our research has significantly expanded its distributional range in Croatia ( Figure 4 ). Morphological identification of larvae was also confirmed by DNA barcoding ( Table 2 ). Analysis of DNA barcoding data indicated an association of larvae and adults of D. schmidi , which has not been done so far. Adult forms of both males and females are well known ( Malicky 2004), and for morphological characteristics of larva there are only preliminary data ( Waringer et al. 2015) because the description of the larva has only recently been completed (Kučinić et al. in prep.). D. schmidi belongs to the group of so-called "yellow" caddisflies (at the adult stage). Unlike the "black" caddisflies from the Drusus bosnicus Group, which are active during the day and have smaller distributions ( Kučinić et al. 2014), “yellow” caddisflies have a more pronounced flight and are active at night. In a certain number of “yellow” caddisfly species, significantly larger distributional areas have been recorded (Marinković- Gospodnetić 1979; Pauls et al. 2006; Previšić et al. 2009) compared to microendemics of the Drusus bosnicus Group ( Kučinić et al. 2014; Marinković- Gospodnetić 1979).
