Danish species per municipalities.

       
Beautiful Demoiselle (Calopteryx virgo)
Denmark
Status: Main distribution range in Denmark is the southern part of Jylland north to Limfjorden. Also relatively common in Nordjylland and on Bornholm. Rare elsewhere. Many observations in the citizen portals away from Jylland and Bornholm are, or very likely are, erroneous. Municipalities not housing any confirmed observations are excluded from the dk-map. These are mainly from Sjælland. Rather common and widespread in Sweden and Finland, less so in Norway.
