Notes

Flight period: I April - III July

The species is rather localised in the study area, occurring in the belt between the south of Lake Como and north to the heavily urbanised area of the Monza and Brianza. There, it is mainly found in mature and well-preserved marshlands and along small streams, covered by rich aquatic vegetation, up to ca. 400 m a.s.l. Historical records at higher elevation (i.e. between ca. 400 m a.s.l. and ca. 1000 m a.s.l., at Piani di Nesso and Lake Segrino; Balestrazzi and Pavesi (2008)) were not confirmed in recent years.
