First data on caddisfly (Insecta, Trichoptera) fauna of peatlands in Croatia

Peatlands in Croatia are rare, small in size and isolated habitats. Due to the abandonment of traditional land-management practices, and particularly to the progressive vegetation succession, they are critically endangered. Caddisfly faunistics and ecology of peatlands in Croatia were never studied. A total of seven caddisfly taxa were collected in this study at three different peatlands ; the Dubravica bog, the Đon močvar bog and the Jarak fen. Collection of Adicella reducta (McLachlan, 1865) represents a new record for the Croatian caddisfly fauna. Additionally, two tyrphophilous species, Hagenella clathrata (Kolenati, 1848) and Rhadicoleptus alpestris (Kolenati, 1848), were recorded for the first time in Croatia after an imprecise literature record from 1935 and the single finding in 1929, respectively. Caddisfly larvae were also collected at two peatlands, belonging to the genera Beraea Stephens, 1836 and Ernodes Wallengren, 1891, which are often collected at peatbogs in larval stages.
