Danish species per municipalities.

       
Broad Scarlet (Crocothemis erythraea)
Denmark
Status: Wide expansion into N Europe. First observation in Denmark was in Jylland in 2015. It is still a rare visitor but with increasing numbers each year. Breeding has been confirmed during the last couple of years in various places, why the species is to be considered an expanding Danish breeding species from now on. Being an opportunist adapted to a variety of habitats, I'm sure the species is more widespread than what's indicated by the map - at least in the southen part of the country.
