Robber fly

thank you mjgierke and KarenL. I have added the name asilidae for now. and also have added a new pic from slightly different angle from the last. Hope it helps in identification.

Great shot! You are right, it is some species of robber fly. As it is unlikely you will be able to get down to exact species level with this view I suggest you add the genus name - Asilidae in the scientific name box for now & them update it if you are able to get a match. http://en.wikipedia.org/wiki/Asilidae

it is a robber fly but its harder to ID it further
