I saw something in the grass and quickly photographed it (head on). Sadly when I moved to try a different angle it flew off. Is it possible from this angle to say what it was (I don't even know if it was a fly but I've put this question here as that is my best guess).
Thanks. My guide to insects illustrates 8 different robber flies but all from above - so not much help. 55 years ago, when I was a young lad, I used to have an aircraft identification book which showed all the different aircraft from the side, above and front on. Shame my insect book doesn't do the same!
There is a very good book that covers Robberflies (British Soldierflies & their allies, by Stubbs & Drake) and, when compared to many fly groups, is quite accessible to novices. But it is still a group that frequently requires specimens and a microscope (or a series of excellent close-up photos from different angles) to be able to make a confident species-level ID
