Sympetrum danae (Sulzer, 1776)

Native status

Re

Conservation status

erl: LC; irl: LC

Notes

Flight period: III June - III September

The species occurred in the past, until at least the 1970s, at the Piani di Nesso and Pian del Tivano fens (located a few km apart). Despite ad hoc research conducted in 2022, that population has to be considered nowadays extinct. In the past, it should have been much more abundant and occurring at lower elevations, as was the case in Trentino ( Assandri 2019, Assandri 2020). Two records in the Pian di Spagna and Lake Mezzola area (27/06/1985 and 17/07/1986), one at Lake Pusiano (21/09/1972) ( Balestrazzi and Pavesi 2008) and one more recent observation (11/08/2015) at Monte Muggio, Casargo LC (ca. 1540 m a.s.l.; G. Bazzi obs., Fig. 3 g) are probably attributable to the individual moving from nearby populations.
