The authors detail a survey of macromoths carried out from 2015 to 2020 in the area of Torrion Quartara of the municipality of Novara (Piedmont, NW Italy). The site still retains many of the original vegetation characteristics of Po Valley, a factor which enabled the survival of numerous species linked to humid and subhumid environments that are greatly threatened nowadays by extensive farming, urban developments, and global warming, thus highlighting the need to carefully preserve the environmental integrity of such rare lowland remnant of primeval habitats once widespread in the area.
