No, as far as I can see this is not Neria nigricornis. That species has dark 3. antennal segment and a mesonotum that is shining except for greyish pollinose anterior part and lateral stripes. I can't see these characters on the the photos. Beside that, N. nigricornis can hardly be expected to find in Denmark. In Sweden it is only found in the northern part of the country, especially in the mountains.
