16. Somatochlora metallica (Vander Linden, 1825) Conservation and breeding status: LC (EU), LC (IT), NT (MED), B?

The congeneric euro-sibiric lentic S. metallica is a lowland species which was observed frequently in EXP in slow running water habitats (4,6); breeding was not confirmed, although it seems likely. Boano et al. (2007) reported it as the most common and widespread corduliid in Piedmont, though records from VCO were still missing at the time; S. metallica was later reported to be common also in north eastern Piedmont, mostly at low altitudes and in the central and southern part of the province, including one record from EXP (Clemente et al. 2011). All data collected in this survey represent new sites of occurrence for VGNP and VCO. S. metallica was the third most abundant species in the park.
