black-insect-landed

Observation - black-insect-landed. Description: I have seen these last week, in more than one places in Cambridge. Near edge of path/railway/hedge/grass, flying in small swamps, pitch black, about 2cm long. Looks nasty but not attacking me. They are not ants. Sorry not good photos.
