Trithemis annulata (Palisot de Beauvais, 1807)

Native status

R

Conservation status

erl: LC; irl: LC

Notes

Flight period: III June - III October

This species colonised the study area in 2019, following a general tendency to expand northwards, which led to the colonisation of Lombardy the year before ( Gheza et al. 2019). All the reported records are localised south of Lake Como and below 380 m a.s.l., except for an individual record at Lake Piano (Fig. 3 h). Repeated observations at some localities (Lakes Sartirana, Annone and Alserio) suggest that the species have started to breed in the study area.
