What kind of beetle is this?
As @Ilan wrote, this is a Cantharidae but most probably Cantharis fusca, which is very common species in northern Europe. Cantharis rustica is similar but has reddish femurs and the black spot is more centered on the pronotum. It is not C. lecontei, which is a North American species. 

If you go looking at flowers of Anthriscus sylvestris for an hour or two, you will most likely see at least Cantharis fusca, Cantharis rustica and Cantharis obscura - they are all very common in Scandinavia during early spring/summer. The larvae of all these species live on the ground/in plant litter as predators.
