Danish species per municipalities.

       
Dark Bluet (Coenagrion armatum)
Denmark
Status: Fragmented populations in Denmark are probably declining because of eutrophication and poor ability to disperse. Currently present in Jylland and Bornholm. Disappeared from Sjælland in year? There is a record from Hvidovre in arter.dk from 2012, but as always with observations imported from "Danmarks Miljøportals Naturdatabase" there are no documentation, why I exclude it from the DK-map. Probably same declining tendency in EU in general. Extinct UK.

Not seen: Endelave, Rømø, Anholt.
Single record, 2003, Holmegaards Mose (Næstved).
Few records Utterslev Mose, 1906, (København).
Few records near Hillerød, 1910-11.
