Danish species per municipalities.

       
Keeled Skimmer (Orthetrum coerulescens)
Denmark
Status: Historically the species has probably been absent from Denmark. Around the beginning of the previous century there were only few records from the region between Varde and silkeborg, Jylland. And it was not until 2006 that the species was rediscovered - this also in Jylland. Since then it has been expanding steadily. Mainly northward through Jylland with the stronghold being the central and westcentral part of the peninsula. It has reached north of Limfjorden with a few records so far, and Fyn too. In 2023 a single male was found on Lolland giving promise to a further expansion up through the eastern part of the country. 2 undocumented records from respectively Helsingør and Høje-Taastrup listed in Danmarks Miljøportals Naturdatabase sound dubious (no evidence), as they occurred back in 2009 and 2011 before the species started the Danish expansion. This said, there have been a sound population in Sweden nearby, why, of course it can't be ruled out that animals have traveled from there to Sjælland.
