Flight period: I July - I September

It mostly occurs at ephemeral habitats and marshlands in the lowlands; dispersing individuals can be found also at higher elevations (a single record at Camaggiore fen, ca. 1160 m a.s.l.; G. Pirotta obs.). Most of the recent records likely refer to dispersing individuals, although breeding attempts are possible at the southern edge of Monza and Brianza Province, which is close to known breeding sites. Historical records from Pian di Spagna, northern Lake Como, Lake Segrino, Lake Annone, Lake Olginate and Adda River, suggest a much wider distribution in the study area at least until the 1990s. This is in accordance with other evidence elsewhere in Europe and northern Italy, reporting that, before the second half of the 20th century, the species was largely confined to temporary wetlands and wet meadows flooded by melting snow, such as the flood plains of mountain valleys. Subsequently, it almost disappeared together with these habitats and now it mostly occurs in artificial habitats with variable water levels and maintained at early successional stages ( Boudot and Kalkman 2015, Assandri 2020).
