Attract wide range of insects with positive phototaxis (wil- liams 1939 ; blanton et al. 1955 ; hartstack et al. jr 1968 ; szentkirályi 2002 ) e.g. species of lepidoptera (baker and sadovy 1978 ; maelzer et al. 1996 ; jonason et al. 2014 tikoca et al. 2016 ), coleoptera (kádár and szél 1995 ; jár- fás and tóth 1977 ) and trichoptera (waringer 1989 , 1991 schmera 2003 ; stanić-koštroman et al. 2012 ; larsson et al. 2020 ). the order of trichoptera is the most species rich taxa of primarily aquatic insects (adler and foottit 2017 ; morse ) and they play essential role in food webs both of freshwater and neighbouring terrestrial ecosystems provid- ing food source for many predatory taxa (e.g., fish, crayfish, birds, bats) (jackson and resh ). consid- ering these features, they are commonly used indicators of water quality, which are sensitive especially for high sedi- ment and nutrient concentrations (resh and unzicker 1975 lenat 1993 ; resh ; barbour et al. 1999 ; dohet jehamalar et al. 2010 ). depending on targeted insect taxa, aim of the given
